Good Morning!

My water supply at my "getaway" home in the Ozarks comes from a well. The system is about 17 years old. It is working just fine. My question is this: The pump cycles about every 7 minutes, without demand. Is this normal?

Thanks for the input!

no, it is not normal.
there is a check valve somewhere that is leaking by.

....or a leaky toilet, or an outdoor wall faucet that is leaking, or an underground yard hydrant that is leaking, or....

i assumed that when he said "without demand" that there was no leak/s.
so the answer is two part..
a check valve letting water back into the well.
OR an unknown demand such as a leaking toilet etc..

Are we talking about a jet pump or submersible pump ?

It's a deep well submersable pump. After the water tank reached full pressure I closed the valve on the well side. This left the home side pressurized. It did not lose pressure. Therefore I ruled out a leak on the house side. This installation does not include a check valve in the house near the tank. The foot valve at the pump or something else must be causing the drop in pressure. What is the down side to just installing a check valve in the supply line before the tank? Should I pull the pump to determine the problem?

Thanks to all

If you install a check before the tank now, and you have a leak somewhere before it, you may end up with the line leaking out and possibly drawing air inside it, since the pump won't kick on to repressurize (providing that the switch is by the tank)
