Will the water drain out of an electric water heater if no water is going in?
yes, but you have to open the relief valve or one of the water connections to allow air to enter the water heater otherwise it will become air-locked and not drain very well.
What causes loss of water pressure in a home with on well water?
There are hundreds of reasons why pressure loss from a well. 1 pump switch is bad. 2. pressure tank has no air inside it. 3 pressure tank balloon bursts and pieces are slowing water flow. 4 under ground leak. 5 corroded water pipes. 6 softener is plugged or filter. 7 check valve is bad. 8 well pump is going out. 9. to many fixtures on at one time. 10. water heater relief valve is leaking. 11. I just personally don't no!!
What is the function of foot valve in the pump?
A foot valve, in relation to a water well, is a check valve at he bottom of a well to keep the water from running back into the well from the pump when the pump is not running. If the check valve does not hold the water the pump will lose it's prime and will not pump water.
Can water tanks explode from well water?
I've never heard of that. Most tanks are built to withstand at least 150 psi and most domestic pumps will not reach that limit.
Can well water overflow?
Yes, at that time You may need to replace the pop off valve. This valve is designed to relieve the pressure on the water heater if something should go haywire in the heating controls,before it explodes. They wear out like anything else. They cost less than 20 bucks.You may have to sweat the relief valve pipe loose and unscrew the old one from the tank. The unit will need to be shut down. The water supply will also need to be turned off.
Who need to use a diverter valve?
A diverter valve is used in turbocharged car engines as part of a pressure relief system. It helps to prevent a compressor surge as well as reduce the wear and tear on the engine and turbocharger.
What location in a well water system should the check valve be placed?
In the incoming water line from well, before pressure tank.
What does a snifter valve do on a water well system?
Introduces air into the system at an atmospheric pressure
How often do you replace relief valve?
I assume you mean a relief valve on a hot water tank. According to the tag on it it should be "popped" once a year by the home owner or a professional (Be careful not to scald yourself if you choose to do this yourself, the water is HOT) to ensure proper function. Proper function means it holds water properly after it has been "popped". It may leak after it has been opened. That can normally be fixed by popping it open a few times and washing any debris out of it. There is no guarantee however that it wil reseal properly. If it fails to stop dripping it must be replaced. NEVER CAP A DEFECTIVE RELIEF VALVE. See youtube mythbusters video on blowing up a hot water tank to see why. The tag says that it should be inspected by a plumbing professional once every 3 years. If it is not working properly that it should be replaced. I have replaced relief valves that were 2 years old, however, I have seen 20 year old tanks that still had the original relief valve on it. So to answer your question if it leaks or fails to open on its test, replace it. If not then don't. The correct way is to REMOVE the T&P every three years and physically inspect it BUT since it is already out may as well as replace it If your going to ask a "plumber" about safety devices ask them if they took the ASME section IV course or studied the NBBI code and are the familiar with NFPA 54
We have an old well lined with stone that isn't keeping up with our demand for water. Can I haul water to put in the well?
You will have to dig the well deeper and adjust the length of the pipes to reach the water where the foot valve or pump is.
How do you shut down water heater while on a vacation?
If you want to shut it down completely, turn off the cold water stop going into the hot water tank. If it is an electrical tank shut the breaker off to the HWT. If it is a gas HWT, shut off the gas valve as well.
What happens if the snifter valve goes bad on the well system?
I think that is what caused my water lines to have too much air in the water
