I have a shallow well system with pump and tank inside the house. The system has, for some time, been finding air somewhere along the way. More troublesome is that the system is now losing pressure slowly, most noticeable overnight. The drop rate is about 1 psi per hour, or about .3 gallons.
The captive air tank bladder is ok and maintains its pressure. Toilets and faucets do not leak. I replaced the foot valve in the well and saw no change.
The polyethylene pipe that descends into the well retains some of its original curl and has the foot valve cocked about 20 degrees off vertical. Is it possible that angle prevents the valve from sealing completely?
On other posts, I see a strong conviction that, in order to prevent air leaks, poly pipe must be softened before inserting barbed fittings. Will that still be effective if you are inserting the fittings after they have previously been put together without softening?
Any advice or insight will be greatly appreciated.
