Had an issue with my well pump, it was running every half hour even with the house main valve shut off. Called a well repairman, he said the check valve in the well on top of the pump was leaking so $1400. He replaced the pump. He installed the new one, the pump ran for 15 minutes and would not shut off, he shut it off via the pressure switch manually. He told me don't worry leave it off over night and all would be well ??? He said he blew air into the well when the pump was removed and this disturb everything in the well and it was normal for this to happen. The next morning I flipped the pressure switch and it worked fine, that evening the pump turned on while using water and wouldn't shut off. I called he said I need a new well, he complained that the depth of the water the pump sits into was only 3 feet and it's not his problem. Seems odd to me , I never had a problem until he touched it ......... Any suggestions would be appreciated, I hate to have a new well drilled if I really don't need one. Thank you, JeffS.
