I’m installing a 1-½ HP Goulds J15S Jet Pump to pump water from a cistern. My pressure switch is set at 40/60 psi. Goulds says that the maximum shut off pressure for that pump is 80 psi (at five feet total suction lift).
Is it advisable that I install a pressure relief valve? If so, should I use a 75 psi or 100 psi valve?
