Re: Well pump question
with all the pressure off your tank ( all water drained) with an air gauge, you should read the pressure your upper limit is set for. In your case it should read 40psi. Is your pump kicking on when there is no water being used? Mine does that, and further investigation shows I have a slow leakdown in the feed,. Our guess is the check valve at the pump is weak or leaky. If you have a small compressor, put sir in the valve on the tank up to 40psi, then monitor it for a while.
I gotta go agitate the techies!
