What Is the Science Behind a Refrigerators?

To make it high efficiency all the components have to be good. So a refrigerator is an insulated box with a door. In the box are pipes to carry a cooling liquid to the outside where the heat it picks up is transfered to the outside air. To move the cooling liquid is a pump. This is controlled by computer or thermostat and there might be other things such as a light inside and outside. So simple things: Lights - make them energy efficient types such as LEDs rather than traditional incadnescant types (which will heat up the fridge when they are on as well) Insulated box - use the best insulation that yuo can and as thick as you can get away with Door - use a similar idea, thick and as good as you can insulation, and make the door seals as good as they can be to prevent draughts into it Cooling liquid and pump need to get the heat out of the fridge with as little energy use as possible, So highly efficient motor and a cooling liquid that transfers heat as well as possible (this is why fridges used to use CFC's - a more efficient heat transfer than say, water) Hope that gives you a start

2. working function of hand pump?

to pump water or air is the flippant answer I am going to assume you mean one of those old fashioned hand pumps for water. There is a hollow tube. There is a circular piece of metal that fits very closely the size of the tube. This is attached to the rod that is attached to the handle. When you push down on the handle, the circular piece moves up. When you pull up the piece moves down. Now when you push the handle fast enough the piece of metal moves up so quickly it leaves an area of considerable low pressure. Now all the air and water will be pulled to this area of low pressure to fill the gap. This will be enough force to combat gravity, and water will be pulled up. Then the pump is designed so this water will trickled out of the pump. A hand air pump does the same thing with the tube and the circle and the rod. High pressure forces the air out, low pressure draws the air in all pumps should work on this premise. The powered ones just use a motor instead of hand power. (I came to this conclusion by myself. Google or wikipedia, or howstuffworks.com to get a more informed source)

3. Help with fuel pump issue?

Your 1986 Sammi was equipped with a carbureted 1.3L inline 4 cylinder engine as stock equipment. If it's still got its original equipment, it will have a mechanical fuel pump located at the top, rear corner of the engine on the passenger side. It's located on the cylinder head, just under the valve cover mounting flange, not the block itself. You should be able to remove the air filter housing from the carburetor and, using your hand, follow the fuel line from the carb back to the pump. A stock replacement pump is about $50 or so at most auto parts stores today.

5. Is a breast pump completely necessary?

I was always AROUND to feed my first baby, and did not bother to get a pump... Then I broke my knee and needed surgery, and needed to run right out, buy a pump, and suddenly leave Dad with the 5 month old who had never in her life had a bottle before... It worked, but was really stressful for all of us! So with the next two, I made sure to pump occasionally and practice, just so the babies knew how it worked and I knew if it's necessary, it wo not be a disaster again. The other thing pumps are really helpful for is if you get a clogged duct when the baby's teeny and not a very strong feeder yet- saved me from antibiotics two times when I had the beginnings of mastitis. A cheapo pump will work just fine, and then you can always see if you need a better one. (And check craigslist/ebay for used ones and then just buy new tubing, etc...) Best of luck to you!

Where Is the Fuse for the Fuel Pump on a 1999 Chevy Subruban?
Where is the Fuse for the fuel pump on a 1999 Chevy Subruban?i am not 100% sure on this but you can call your local chevy dealers service center to double check. the fuse box inside the vehicle is not the location of the fuse. there is a fuse box located under the hood on the drivers side and the fuse for the fuel pump is not always labeled as "fuel pump". you will notice there are several ecm fuses (ecm-b, ecm-a, ecm-i). i do not recall exactly which ecm fuse it is, but its one of those— — — — — —How easy is it to replace a fuel pump?you can A) take the bed of the truck off and access the pump from there B) remove the tank straps, drop the tank (usually after being emptied), and then pull the pump. takes a few hours— — — — — —Fuel pumpA fuel pump is a component in motor vehicles that transfers liquid from the fuel tank to the carburetor of the internal combustion engine. Carbureted engines often use low pressure mechanical pumps that are mounted outside the fuel tank, whereas fuel injected engines often use electric fuel pumps that are mounted inside the fuel tank (and some fuel injected engines have two fuel pumps: one low pressure/high volume supply pump in the tank and one high pressure/low volume pump on or near the engine). Fuel pressure needs to be within certain specifications for the engine to run correctly. If the fuel pressure is too high, the engine will run rough and rich, not combusting all of the fuel being pumped making the engine inefficient and a pollutant. If the pressure is too low, the engine may run lean, misfire, or stall. Many engines (older motorcycle engines in particular) do not require any fuel pump at all, requiring only gravity to feed fuel from the fuel tank or under high pressure to the fuel injection system.— — — — — —how do you turn the fuel pump on and off on a 1989 ford f250?I believe there are two electrical pins on the EEC-IV connector under the hood that you connect together to force the fuel pump to run. The connector should be on top of the driver's side fender wall inside the hood compartment. Read the Motors and Chiltons manuals at your library for the EEC-IV connector pin-out functions.— — — — — —Tips to Keep Your Truckee Auto's Fuel Pump HealthyA friend of mine in Truckee has a Toyota that just sputtered and the engine died while driving on Interstate 80 over Donner Summit. She was a Red Check Club member at Quality Automotive Servicing so she received a free tow to our Truckee auto repair shop. Turns out she needed a new fuel pump. We were happy to help her out and get her back on the road safely. I can already hear you saying "How do I know if I need to replace my fuel pump? I Do not want to be stranded in snowstorm." Unlike other maintenance items on your Toyota, the manufacturer gives no suggestion for when to change the fuel pump. Since it is located inside the fuel tank, you can not inspect it without removing the tank. There are some things you can do to give your fuel pump longer life. First, avoid running your fuel tank empty. This causes a fuel starvation scenario that puts stress on the fuel pump. Second, be sure to change the fuel filter as recommended, The fuel filter will filter dirt and rust from the gas tank before it gets to the engine so replacing a clogged fuel filter will reduce stress on the fuel pump. Third, you can not go wrong spending a little extra and using "top tier" fuels with higher levels of detergents than the cheaper alternatives. This better fuel prevents build up of gunk and varnish. Lastly, a system cleaning, such as Motorvac, will clean fuel injectors and help remove the deposits and gunk from the valves and combustion chamber. Here's a bonus, all these things will also improve your Truckee fuel economy and vehicle performance. That's a real bonus when you are climbing Donner Summit or Northwoods Boulevard. Quality Automotive Servicing are Truckee and Lake Tahoe auto repair specialists. Ask them about symptoms that might be an indication of a failing fuel pump like sputtering and the engine dying unexpectedly.
1997 Toyota Rav4 Timing Belt and Water Pump?
1997 Toyota Rav4 Timing Belt and Water Pump?
"Do not use Water...Anti-Freeze & Clean Water=Coolant" At 200,000 and Overheating it Sounds like "Rebuild Time"1. Solar powered water pump for sprinkler?This project may be very poorly considered. Solar power is costly on a capital cost per watt basis. You would want to use that costly power to do things for you all year round, not just when your garden needs water. For any pumping role, your solar panels will not provide good starting ability, particularly when the sun comes up. You will need battery power to build up some charge to start the motor under pumping load. Your system then has to be designed not to try to start the pump when there is not enough charge. Late in the day, or when the sun wanes, you also need to have the pump stop running if the voltage drops too low. It just waits for the battery to regain charge, You will get more water delivered in drip mode than via sprinkler, and with less sunlight. Sprinklers will waste at least 30% of the water and 45% of the energy. If you use an inverter between battery and pump, you can use cheap ac pumping motors, but additionally you can use the power in your house. If your only application of power is pumping, and you are far from neighbours, you might want to consider using a wind turbine, as it will give more kwh per dollar. But in the village, and powering household uses, solar is a good alternative.2. Replace the water pump on a 1992 Pontiac Sunbird LE?The best thing you could do is maybe run to a library and they might have a Chiltons or Haynes repair manual you can make some copies of, check it out and decide for yourself, but a timing belt is a pretty involved process, not so much for a water pump3. Can a car water pump work at partial capicity or is a matter of it pumps or doesn't pump?You got one of the money making shops. If you go for this they will give you a BIG bill and you will have the same water pump. Water pumps go bad when the mechanical seal fails and they leak. No other reason ---if it ai not leakin it ai not bad. The only way you could have a "weak' pump would be a slipping belt and that would create an overheat problem. I do not know if you have a heating problem but if you ever do go to a RADIATOR SHOP not a rip off auto repair. Do not fall for the thermostat thing either--same scenario big bill--- same thermostat. Water pumps and thermostats do not cause overheat problems except in extremely rare situations4. Air Locked Water Pump?If you are using a standard well pump, then there should be a check valve in the pipe between the holding tank and the pump. In a well it will be a foot valve, but may also have been a simple check valve. The work on your mains may have introduced dirt into the valve and prevents if from sealing and maintaining the pressure in the system when the pump stops. Someone also suggested that the pressure tank (not the holding tank) associated with the pump has become water logged. If that is the case then a small volume of water coming out of the pressure tank will cause a large enough pressure change to keep the pump working. Last possibility, there has to be a sensor that determines that the level of the water in the holding tank is low and will turn on the mains supply and when the level gets high enough that the mains supply is turned off. This can be a pressure switch or a mercury switch similar to one with a sump pump, etc. So my suggestions are: Check to make sure that the holding tank is clean and there is no sediment in it. Check to make sure that the holding tank fills when the water level drops, (it appears to stop when it is full). If you do this next procedure, make sure that you know how to prime your pump. I would also turn off the hot water tank. If it is a foot valve, remove the foot valve by removing the clamp and then back wash it to clean out the dirt. If it is an in-line check valve then remove the pipe. between the pump and the holding tank and invert it, and run water through it to clean out any sediment, then replace the pipe. Drain the pressure tank, and if you can pump some air into it. Then make sure that everything is connected, prime the pump and turn it on. Make sure that everything is working, then at each tap, especially the hot water taps, turn them on and leave running until the water flows smoothly. When all of the air is out of the system then turn on the hot water tank.

This happens in non-diabetics too when they are exercising or have not eaten in several hours. It's the same thing that happens if you have an emergency low and use your glucagon kit. I get very disoriented from being low, so I keep a bowl full of Skittles in my bedstand drawer so I can just grab them when I feel it come on. Have you done some fasting basal tests recently? Your basal needs may have changed, and I wonder if you have dawn phenomenon that might be causing the morning high. Eat a low-fat dinner around 6pm and nothing more for the rest of the evening, then test your BG every hour on the hour starting at 9pm. That means you will have to set an alarm clock to go off every hour during the night and keep your meter right by the bed to test so you can go right back to sleep. It will be a sketchy night's sleep, so maybe do this on a Friday evening/Saturday morning so you can get a good nap in the next day.

I can shower with it, and though the edges start to peel back (at times) the dressing stays covered and dry. It can last for up to 7 days without needing changed (under the right circumstances). I am not sure how often you change your needle, but I am sure something along the lines of a Tegaderm covering would be beneficial to you. Most hospitals and doctor clinics have access to these, and provide them at little to no cost. I would ask your diabetic doc about it.

Where are the ac relay and the fuel pump relay located in a 2000 Blazer?They are located in the fuse box thats under the hood. or sometimes is labeled relays2. Where is a fuel pump relay on a 1990 camaro?Cant exactly tell you on that car but your best source would be going into a part store and picking up a HAYES book on your year and it will tell you all about location of the fuel pump relay and show you pictures. Then after you looked at it go to the counter and ask if they have it and see how much it is3. where is the fuel pump relay located 2002 ford windstar?it should be in the engine bay fuse box. i would look in the book for the exact location and then also look up info on the inertia switch. that could be the problem there4. how can you tell if the fuel pump relay is out on youre 1993 dodge spirit?If you touch or feel it or listen to it as someone turns the ignition the relay should buzz or vibrate etc and that tell you it seems to be working , otherwise try another less vital relay switch them bec that vehicle probably has a few relays with the exact same part number on them. Basically one of the relays socket connectors should give out a positive 12 volts at all times , then as the ignition is turned to the start position another relay socket connector should give you a positive 12volt reading , so if you had a 12 volt test probe grounded it lead wire to the battery's negative post , then popped out the starter relay the socket should have one life pin then another when the key is tuned , and when the relay is in the socket the relay switches on and sends the 12 volts to the fuel pump.I've stripped some wire and wrapped it tightly around a relays leg or pin then made sure that wire is not shorting out against any other pins etc , test it with the probe , do this with the ignition in the run position and you should find 3 of the relays pins do light up the test probe and that say it's working. Hope that helps and best of luck.By the way that method is the easiest method if you can not gain access to the pump or it's wiring etc but remember that if the relay is working and the 3 points are live trace the wiring bec it could be a bad wire or bad ground.5. I've got a car problem........?You need to take the gas cap off and put your ear towards the filler neck and then have someone turn the key to the on position, not start.If you hear a little noise like a pump running, then your pump is probably working.If the car will not start you can also have some one try to start it and you take a broom handle and hit the fuel tank several times while cranking the car. that will some time jar the fuel pump to work. Now it may not be your fuel pump, you can replace fuel pump relay, usually under the hood.in a black box full of fuses. But you can have a bad fuel pressure regulator also, I believe some of the ford product have had this problem..also it could be the computer It may not be a fuel problem, it could be a ignition problem and that is a whole different story. Over all there is so many things it could be, you would probably save money and time and take it to a good automotive repair shop, with a ase master technician and let him run the proper test to pin point the problem. before you spend your money on things that may not fix the problem.6. where is the fuel pump relay located on 530i bmw 1995?Just had the fuel pump replaced on a 1994 BMW 325i and it was $500 with labor.

Heat Pump Problems? Heres What You Need to Know.
Heat Pump Problems? Heres What You Need to Know.
Heat Pump Problems? Here’s What You Need To Know.The temperature drops and your heat pump fails. Go figure. But is the issue serious enough to call a professional? What is normal and what is not when it comes to performance? If you think your heat pump may need maintenance, read on to learn about common issues that affect them and what you can do. One of the most common heat pump problems is that it's simply not running. The culprit may be easy to spot: the thermostat. Make sure that your thermostat is set correctly - to "Heat" and on the appropriate temperature - before doing anything else. If the issue is not resolved, there may have been a malfunction with the wiring of your thermostat. An electrician or residential heating repair technician can diagnose the issue and reconnect the heat pump and thermostat correctly. If your heat pump is not running, it could also be a sign that it has lost power. This may be due to a tripped circuit breaker or blown fuse in the heat pump's air handler cabinet. If you are used to oil or gas furnaces, be aware that the air circulated by heat pumps will not feel as hot as what you may have previously experienced. However, if the air blowing from your heat pump is not raising the temperature of your home to the temperature set on the thermostat, there is a problem. One way to tell if there's an issue is to monitor your vents over a period of time. While your heat pump does go through a defrost cycle during which it blows cooler air, these cycles should only last about 10-15 minutes. If your pump is blowing cold air for longer than that, then it's time to call in a professional. The coils of your heat pump might need to be cleaned, or the reverse valve may be stuck. Some rattling can be normal when a heat pump is running, especially if yours is a few years old. Squealing, popping, grinding, and ringing noises, however, are signs that there is an internal issue with the heat pump. This could range from faulty motor bearings to a loose flap of metal inside the pump. A professional can examine the heat pump and even install insulation in your metal ductwork to help lessen unavoidable, but bothersome, noises. A little bit of frost or very thin ice is a normal sight on most heat pumps, especially during the winter. The pump's defrost cycle ensures that there is not too much build-up on the machine. However, if you've noticed a considerable amount of ice on your heat pump - especially on the top - there could be an issue with the pump's performance. Whether it turns out that the defrost is not functioning correctly, the refrigerant is low, or the unit has a broken fan, it needs to be examined by a professional. Do not try to remove the ice yourself; you could end up doing serious damage to the pump. "I am cold. but my energy bill is increasing." Maybe your heat pump seems to be running normally, but it's just not heating your home like it used to, and your bills have inexplicably increased as well. These are common warning signs that your heat pump is underperforming due to its age. When a heat pump gets older, it stops running efficiently. After years of use, heat pumps cannot function at the same level as when they were new, and this dip in performance costs more money as the pump works overtime to heat your home. Simply turning up your thermostat to try and make up for the difference in performance will only increase your bills even more. Energy Star recommends replacing your heat pump at least every 10 years. If you've noticed these issues and think it's time for a replacement, call a residential heating professional and be sure to choose a new heat pump that has a high Seasonal Energy Efficiency Ratio (SEER) and Heating Seasonal Performance Factor (HSPF). The SEER/HSPF ratings reflect the efficiency of the heat pump's performance; they take into account how much energy the pump needs in order to run versus how much heating and cooling power it produces for your home. An easy way to make sure that your heat pump has a high SEER/HSPF rating is to choose a model that has been certified by Energy Star. If you are experiencing any of these issues, call a heating technician to make sure that your heat pump is functioning properly. The residential heating professionals at IT Landes can diagnose any issue your heat pump may have and help you find a solution to keep your home comfortable during the winter months.

Have the refrigerant level checked. open the doors in the furthest rooms to increase circulation. do your ducts need to be cleaned? Are the filters clean? Is the outdoor unit clean and free of obstructions with good air flow?— — — — — —How Does a Heat Pump Work?Heat pumps are a great alternative to a traditional HVAC system, but how does a heat pump work? Find out in this guide from the HVAC installation and repair experts at Eyman. A heat pump functions as an alternative to the traditional HVAC system; It's not an air conditioner. However, both air conditioners and heat pumps collect heat from inside your home through a compressed refrigerant. As air passes over a coil within its air handler, the collected heat is subsequently transferred outside. Heat pumps are not furnaces either, they are an all-in-one temperature regulator. This means it heats your house during cold months and cools your house during warm months. While air conditioners necessitate the use of an accompanying furnace, a heat pump requires no such thing. Heat pumps can act both as a heater or a dehumidifier, depending on the circumstances. Also, instead of installing two separate systems to heat and cool your home, heat pumps provide heating and cooling within the same system by extracting heat and moving it throughout the ductwork outside your home. Heat pumps do not generate hot or cold air. Heat is always present, even in the air that seems cold. Even the ground itself contains some element of heat, which allows heat pumps to warm homes on cold days. Simply-put, a heat pump can extract heat from the air and transfer it to another area. When the weather outside is warm, heat pumps extract heat from indoors and push it out. The compressor then moves the refrigerant between the indoor evaporator and outdoor condensing units. The warm air is moved through the air handler along with the refrigerant moving from the exterior condenser coil to the interior evaporator coil. The heat absorbed by the refrigerant causes air to cool, which is finally pushed throughout the ductwork, cooling your home. When it's cold outside, heat pumps reverse. They behave like an air conditioner, using the outside coil as an evaporator and the indoor coil as a condenser to extract the heat from outside and transfer it inside. From there, the refrigerant travels through a closed system between the indoor and outdoor units. The heat pump produces heat and uses a furnace to blow warm air throughout the ductwork in your home. A heat pump is made up of both an indoor and outdoor unit The outdoor unit consists primarily of a condensing coil and compressor. Within this compressor lies a reversing valve, fan, and motor. It also contains defrost controls and all of the system's main electrical components. The air handler must be matched appropriately to the outdoor unit. It consists of an evaporator coil, blower motor, and electric heater. The air handler is responsible for moving air efficiently throughout homes. If the heat pump is unable to effectively heat its particular home, an emergency electrical heater will power-on to assist. The electrical heater consists of all the elements also located within an air handler; the heater pack is the electric heat elements installed in that air handler. Refrigerant is the liquid that circulates through the heat pump system, absorbing or rejecting heat. Its primary purpose is facilitating the process of heat exchange, which enables a pump to warm your home. Refrigerant is a chemical compound that uses minimal energy to convert liquid to gas and back. The compressor pumps refrigerant between two exchanger coils. An indoor air handler consists of a coil and a fan. In cooling mode, the coil acts as an evaporator, evaporating refrigerant at low pressure and absorbing heat from its surroundings. In heating mode, the coil acts as a condenser. In both instances, the fan is responsible for transporting air across the coil and throughout homes. A reversing valve is an electromagnetic four-way valve that reverses the flow of refrigerant using a magnet. When connected to electricity, the reverse valve opens and enables airflow. When disconnected, it closes and flow stops. The reversing valve is responsible for the movement of air in-and-out of your home. A thermal expansion valve is a vital element of a heat pump; it's what makes air conditioning (cooling) possible. The expansion valve regulates the rate of refrigerant flow as it circulates throughout the heat pump system. This regulation occurs through the use of a temperature-sensing bulb. As temperature increases, the bulb opens a valve against the spring. The regulation provided by the thermal expansion valve allows for a reduction of pressure and temperature of the refrigerant. Heat pumps are meant for moderate climates, as opposed to those with extreme temperatures. It's recommended that heat pumps are not used in regions where temperatures fall below 30 degrees. In frigid temperatures, a heat pump can struggle to extract heat, and it becomes much less efficient. Whether you are replacing an existing HVAC system or installing one for the first time, there are a number of factors to consider. If you are not sure whether you should go with a heat pump or an air conditioner and furnace, call Eyman at (402) 731-2727. We will help you find the right system for your specific needs.

This problem prevents your home from receiving the heat it needs and has the potential to damage your heating system. We share tips on thawing a heat pump so you are prepared to take action if this issue occurs. Why Do Heat Pumps Ice Up? In a nutshell, it's all about the water vapor. Even the cold, dry air outside your Cincinnati home contains small amounts of water vapor. When it reaches its dew point, the water vapor undergoes a phase change into liquid form. Now consider your heat pump's refrigerant runs up to 20 degrees colder than the air outdoors. If the cold weather is just right - around 20 to 40 degrees with a relative humidity above 70 percent - there's a good chance that frost will form all over the condenser coils. To prevent frost formation, a heat pump occasionally undergoes a defrost cycle. This essentially takes all of the heat that's being transferred inside your home and instead sends it back outdoors through the condenser coils, thus melting the ice that forms around the unit. Unfortunately, this may not be enough to remove severe ice formation. In some cases, an underlying problem may prevent the defrost cycle from working. As such, it is important you know the steps to thaw a heat pump manually to protect your unit. If your heat pump has visible ice accumulation, follow these steps for thawing a heat pump: • None Turn the heat pump off at the circuit breaker. You do not want it to suddenly energize while you are working on the problem. • None Next, grab a garden hose and spray the heat pump with water until the ice melts. Hammering or chipping away the ice could cause major damage. • None If it's warm enough, you can reactivate the heat pump and run it on "fan" mode until the ice melts. Once you've defrosted your heat pump, you need to determine if there is a clear and correctable source that caused your unit to freeze over. One common culprit is a leaking overhead gutter. Damage or improper pitch causes water to spill out of the gutter onto the heat pump below where ice forms. If you notice a gutter leak, make repairs right away to prevent further problems with your heat pump. All heat pumps, regardless of the age, have a built-in defrost cycle. This is the system's method for defrosting a heat pump. The older units have a mechanical timer that triggers the cycle, while newer units are controlled by a solid state control module and temperature sensors. Either way, the system itself works the same. A well-running heat pump should run in defrost mode at timed intervals and can run from 30 seconds to a few minutes. The defrost cycle helps rid the outdoor unit of frost and ice buildup to prevent the system from freezing over. The entire system is reversed as the air conditioning is turned on, which causes the refrigerant to heat up and run through the outdoor coil to melt ice. The outdoor fan is stopped to prevent it from cooling the outside coil. The defrost will continue until the temperature of the outside coil reaches about 57 degrees. During the heat pump's defrost cycle, the indoor fan continues to run, and your system is in cooling mode. In order to avoid cold air from circulating throughout the house, a backup heating system can be utilized when the pump goes into defrost mode. There are several reasons why your heat pump defrost cycle is not working properly. An older system may begin running the cycle when it is not necessary. In other cases, the defrost cycle may not come on when it needs to, which can damage the heat pump. There are a few reasons this may happen: • None The outdoor coil is dirty or covered with debris If your heat pump defrost cycle does not kick on periodically, it's likely not defrosting the ice. And, if your heat pump ices up too far, the cycle does not have the power to remove such buildup. There are many causes for the defrost cycle to not work, and most of them have to do with the internal parts of the heat pump itself. You need to call for HVAC service to have such issues corrected. When the defrost cycle fails, it falls on you to protect your system by knowing how to dethaw a heat pump. If your heat pump's defrost cycle does not work or the steps how to thaw a heat pump do not get rid of ice, it's time to call for help. Call Apollo Home today for quick and reliable heat pump repairs to eliminate ice and restore proper cycle functioning.
In Gratitude for Jerry
In Gratitude for Jerry
It began with the pressure dropping on March 27th and ultimately we found out that our water association’s well pump was failing. We have black sand underground in our area and sometimes that sand moves and wells that did fine before suddenly begin plugging up. We believe that’s what happened to our well. The perforations in the pipe probably became plugged up and the pump began pumping fine sand. So we put a new pump in the well in hopes that this would solve the problem. My husband Jerry, who has been our system operator for the last thirty years, didn’t believe that it would, but he kept a good thought anyway. This was about 5 weeks into the process and after the new pump went in, the well began pumping even less water, at times only 7 gallons per minute, other times at 25 gallons per minute, so it’s never been consistent since the pressure began dropping.Jerry found that if the water in our 25,000-gallon cistern fell below half, then it would be difficult to get it to recover so he decided to imitate a process called developing the well which is essentially what drillers to do get the water flowing. Every half hour he would turn the pump off and then a half hour later back on to try to stimulate the water to flow. Amazingly enough, it worked although not consistently. So for the last two of the three months he’s been dealing with all of this, he’s been out at the well every half hour on most days. Occasionally he’s been able to go an hour or two if the cistern is relatively full, but then the flow unexpectedly changes and he’s back to his every half hour adjustment. But it did seem as if he got that sand to move a bit so that it wasn’t moving through the pump anymore.Last Thursday, the drillers finally came and began drilling our well, finishing up on Friday. We have more paperwork to submit to the state and then the pump can be transferred over to the new well, but in the meantime, the drilling disturbed the area enough that the old well is plugging again and at times, the water flow is little more than a dribble. So, we’re on water restrictions again. We each have five acres with some of it lawns and gardens, but the rest is pasture. Although we each have flood irrigation for our pastures, horses and the like still need fresh water and they drink a ton of it. So to be on water restrictions is difficult for all of us.And then last night Jerry had to shut the water off to the homes until this morning. The water was down to about a third of the cistern and that’s not enough to get us safely through the day. We can’t have water hauled in until Monday and we need time for the cistern to try to recover without anything going out to the homes. And after filling all night long, it was only up to half this morning. So we’ll continue to conserve until this is done.We’ll be begging the state on Monday to expedite our paperwork so that we can get the pump transferred over. We didn’t know about this additional paperwork or we would have had it submitted long before now. With luck, they’ll sympathize with our plight and let us install the pump sooner than later. This has been so expensive as it is and our funds aren’t endless and $350 only buys us 16,000 gallons of water, not enough to even fill the cistern and if Jerry can get the water to stabilize today the way he did before the drillers disturbed the ground, then we may not need other water hauled in, but at this point, it’s not looking promising.The gratitude I feel for my husband is endless. I know what he’s done for us over the last thirty years to keep our costs down and the water flowing because I was secretary of our association for seventeen years so I know the money he’s saved us. When we moved here in 1981, we were told of our responsibilities on the second day we were here. He was to help with maintenance and repairs. The only people who weren’t expected to help were seniors, disabled people and women living alone, except the women were expected to go to town to retrieve things. What those things were, I never knew. But we all helped out. Work parties would locate leaks on the mainline as well as on the various properties and together we would make repairs. Jerry and the guys would get together and rotate the external pumps to take in for service. It saved us a ton of money over the years and it fostered a sense of community among the owners in the water association. We were in this together.And then we weren’t. And we haven’t been together in this for a very long time.It’s been a difficult three months. He’s had zero help and he’s tired and feels more used now than he’s ever felt in his life. We’re about to become grandparents for the very first time. It can happen any day now. We’d like to be focusing on that and all the things we need to do around our property. Some of the pressure is off because the new well is completed and the guy who drilled it happens to be the best driller around. In fact, this is the same driller who drilled our community well some forty years ago. Jerry worked with him when we first moved to the area as his drilling assistant and learned so much from him so it was like old home week when his former co-worker showed up to drill our well. It was the first day I’ve really seen Jerry smile since all of this began.The good news is that our well is now at 288 feet instead of at 230, and no black sand came through when they drilled. We have 40 feet of perforated pipe at the bottom and 82 feet of water to place the pump in. And the best part? When we start getting water from the new well, it will be pumping anywhere from 60 to 100 gallons per minute, more than enough to sustain 14 homes. The drilling couldn’t have gone better and Jerry is so pleased.I know everyone appreciates what he’s doing. And their gratitude is appreciated, always. But it cannot be in lieu of someone’s presence when that’s what’s needed and when they’re more than capable of helping. He’s asked for help for years to no avail. But still, he continues to take responsibility for this well and cistern because he’s qualified to do so and takes his commitment seriously. We both do. It used to be when the water went off or had problems, owners came over with their shovels and wearing irrigation boots to see what was up. Now they stay in their homes and wait for a guy named Jerry to do something. And I’m so thankful that he does so.It drives home the notion that we’re all in this life together whether we want to be or not. It’s better when we work together on things instead of standing back or getting in the way of it all. The shared sacrifice is worth it in the end, when we can all feel gratitude for one another.Blessed BeWhy do American men wear class rings, but won’t use their postnominal degrees on door signs and business cards?American women wear class rings, too. I wear mine.Generally speaking, displaying where you got your degree from on a business card or a door sign would be seen as odd, at best. If somebody handed me a business card with the Harvard logo on it and he didn’t work at Harvard, I’d probably ask about it: “Oh, do you do work with Harvard University?” and if the answer was, “No, I just attended” I’d find this an unpleasant level of showing off. Not classy.A lot of Americans will have college-related paraphernalia in their offices, though. Like, you may see a pennant or they may have their degree(s) up on the wall. This is a more casual display of affiliation.Likewise, the ring is casual. Class rings are usually not that obtrusive, particularly the signet variety.Usually, the signet is only immediately recognized by others who attended the university (though I have had people ask me to hand over my ring so they could take a closer look at it before), and thus it kind of acts like a secret handshake. I’ve had people from my college recognize my signet ring on sight, and then we have an instant connection.It’s just a lot classier than shoving it in everybody’s face all the time in an American social environment, basically.
Is There a Sump Pump Problem?
Is There a Sump Pump Problem?
If there is an adjustable float switch, you could lower it so it starts sooner. Otherwise, as long as it's never flooded anything- it's fine.1. How do you pump with a manual breast pump?Mostly just a lot! I usually pump slowly, not so much that it really hurts. I did it no problem with my first, but this time I have had a hard time getting much with the pump, but meanwhile my babe's getting nice and plump! So good luck, and if you have a hard time talk to La Leche League. and if you really struggle with yours they might be able to help you find an electric pump, depending on how much you need to be using it. The manual is fine for me, but I am a student and at home most of the time2. Is this a reasonable price for a new heat pump?13 SEER is not high efficiency. 14 SEER and up is. That Company will make approximately $2000.00 profit after all their expenses. The wages they have to pay an employee may cost them about an additional 2 to 3 hundred dollars (and thats a lead hand with a helper) If the installation is done by company owners than its $2000.00 profit. Guaranteed! You could probably do better by getting a few more quotes. Never hire companies without liability insurance. Look for professional looking invoices, quotes, and contract documents (at least have their own letterhead on it). Look for advertising on the vehicles they drive. A company that doesnt bother putting logos and signage on their trucks might be more of a "Fly by Night" type of company. Generally, a company that does alot of advertising and wants to look professional has a reputation that they want to protect, thus many times will provide better workmanship and warranty. Ask to see their license credentials. Are they licensed Refrigeration Mechanics? Who will be connecting the electrical. Alot of HVAC companies do it themselves, when really they need to get a permit or have an electrical contractor involved on the job as well. Most good HVAC companies are more than competant to take care of the electrical, but if you want it done by the book, check your State laws. Ask for a few references from a few of their past jobs. Ask about the warranty. Tell them to write down the warranty on the contract in their own writing as well. Make sure you have them especially write down what kind of *** Labour warrenty*** their company provides you. Dont just let them tell you, or point out to you on a manufacturers brochure, that the product has 5 yrs warranty on it. That is likely just a ***Parts*** warranty. They have to specify "Labour warranty". Ask them if a service call is required within the warranty period, if the cost of the "Service Call Charge" is covered under the labour warranty. Some companies use that little trick as a way of getting money out of you when they are on the hook for the labour. Make sure they are installing completely new copper linesets going from the outside condensing unit into the indoor evaporator coil which is mounted usually downstream in the duct of a forced air furnace or air handler. Make sure you know whether they are installing the old type of system with R-22 refrigerant, or the newer, more environmentally friendly R-410A refrigerant. Lots of times with the higher efficiency systems, the indoor evaporator coil is quite a bit bigger than the older one, so make sure they get some new duct or a whole new duct plenum , professionally fabricated and installed. Dont accept bits and pieces of metal screwed and duct taped together, as a way of increasing the size of the larger required duct plenum. After about a few years it will start rattling and squeeking and keeping you up at night. Ok. ..well, that should get you on the right track. Good Luck3.
