Water pump won't shut off
Hi, I have had this problem for 3 weeks now and is about to kick the bucket. I am not a well specialist by any means but I have some plumbing knowledge. It all started with the pump not shutting off. The pressure will only go up to 30 psi and stay there until I shut it off manually. I have a shallow well, a 52" bladder, 1/2 hp craftsman water pump and water softner. I originally installed a 40/60 psi switch but since the pressure never built up that high I replaced it with a 30/50. I have been reading other threads relating to this subject and yesterday went out to buy a new tank because the air pressure in the bladder is always @ 10 psi by early morning. I have also replaced all the pipes with new. After installing the new tank with pressure at 28 psi, the pump pressure will now not go above 20 psi and won't shut off. The water pressure in the house is pretty dismal. There was a crack in the pipe from the well but I covered it up with cement so there is no leak there. Is the problem with the pump or do you think there's debris in the pipe? How do I clean this if this is the problem?
