I have a jet pump for my dug well. I went down today because I heard my pump kick in a couple times in a minute. What I see is my pressure is at about 25psi. So I turned water on And pump kicks in for about 20 seconds building pressure to about 25 then shuts off. My pressure switch is set to 60psi. I popped the top on pressure switch and notice that contact is made but pump is off. It just kicks back in on its own after about 30sec but shuts off every 10sec. Shuts off when pressure reaches 60psi (that’s what high is set to)Weird thing is contacts never flip off. I drained the system and checked pressure tank, it is charged to 18psi (cut in is set to 20psi on switch) Is the cutting in and out a sign of a bad bladder? Only house I have not gotten off is the little tube from pump body to switch but I figured if that was clogged would the switch not stay closed and pump run continuous? Any help would be appreciated.
