The pressure switch controlling my shallow well jet pump has a low pressure shutoff. For the past couple of months it has been tripping due to low pressure more frequently than I would expect - about every two weeks.
The odd thing is that this happens during periods when there is little or no usage. I am confident that my system is fairly tight. We recently had a 12 hour power outage and lost very little pressure over that time.
The pressure switch too is fairly new. Less than 2 years old.
Any thought about where I can begin trouble shooting this problem? Should I try opening the well so I can take a look at the foot valve?
