|In response to Re: shallow well pump problems|
A 15 amp breaker is probably adequate for a 20 - 40 pump, but the breaker tripping at 30 psi indicates that the pressure regulator is telling the pump to start at 30 rather than 20. No big deal actually, but the total electrical amperage demand is what is tripping the breaker. That indicates either that the pump motor is trying to start while there is still too much pressure against the impeller, or else that the brushes or windings in the electric motor are leaking current, and causing increased amperage draw (more than the allowable 15 amps). It isn't likely its the breaker, or a pressure problem but more likely a motor issue. Not knowing how much of a semi-amateur you are, you might be able to replace both the pump and motor, but there are many, many variables. First, is there a valve between the tank and the pump to prevent the storage tank from draining? If not are you capable of plumbing one in? If not, you would be better advised to contact a LICENSED plumber to do the job for you professionally.
