I have a one hp projet pump running the water on my house and a
challenger series bladder tank. As soon as I turn on any water the pump
turns on and runs until I turn off the water. Both the pump and bladder
tank are only a few years old. Can anyone tell me any ideas why the
pump turns on and runs like this? I did check the bladder tank and the
psi is 28. This two psi's below the 30 it is rated for, which every
where i have read is where it should be.
