: I have just installed a new sears deep well water pump. It won't pressurize beyond 40 psi, and it won't shut off. The tank is pressurized to 5o psi and there are no leaks visible. Any suggestions?

Are we talking jet pump (is it in the well or out). is the jet package that is in the well matched to the pump correctly? Check for air leaks. soap suds work well for this. put them on the joints and see if they suck in. The precharge in the pressure tank should be two pounds less than the pressure that the pump is set to come on. a 30- 50 pressure setting would require a 28 pound precharge in the tank. be sure to test the precharge with all water pressure drained off of the system. A 50 lbs precharge normaly would be to high. However the precharge wouldn't keep that pump from building pressure
