Most plumbing experts agree that if you are having a problem with a leaky check valve at the pump or in the well, it's best to replace the valve. Inherent features include a large free area with resulting low-pressure loss, high integrity sealing from the continuous seal design, reduced noise and wear by the elimination of metal to metal rotating parts, and stable operation under a wider range of flow rates. Or see CHECK VALVE FAQs - questions and answers posted originally on this page. Where do we find the water system check valve (if any) and why are check valves used on pump and well systems? If your pump motor starts while this is in progress it would place a heavy strain that may cause the pump shaft to break or the motor thrust bearing to be damaged. Spring loaded check valves close quickly, prevent water hammer, and protect the pump or impeller assembly from back-flowing; most importantly a properly functioning check valve prevents loss of prime in the well piping system. Specially designed for deep well applications, TECHNOs standard female threaded check valves are rated for 450 psi service or depths of 1000 ft. But there are some other things to check. But doing so allows inspection of the well line - you may discover that the problem was not even the foot valve, but a hole in the well piping. . JD Apologies for the delay.
