System is as follows: Well pump, holding tank, pressure pump, house.
At the pressure pump, I have it set up where the feed is coming from a lower bulkhead on the tank instead of an upper, so water flows down into the pump instead of the pump lifting the water (what these shallow well pumps are designed to do).
Normally you'd use a foot valve, but that wouldn't work with this setup.
So do I just stick a standard half pound spring check valve between the tank and the pressure pump? Right now the pressure pump won't maintain pressure, because it back feeds into the tank every time it clicks off.
