I'll be replacing the original Jabsco Sensor Max 14 Fresh Water Pump, model 31750. It is running constantly even when all faucets are closed. It only shut off at the breaker. When the breaker is switched on, the pump immediately starts running loudly without an open faucet. I'm curious as to your thoughts on the best replacement for it. I had good luck with Jabsco. It's sensored controlled; 35 PSI.
