![]() In turn, it keeps your RV pipes from bursting or the fittings from leaking. You can install an accumulator to reduce this if the noise and vibration bother you.īecause this is a constant-speed pump, it uses a pressure switch to turn the pump on and off as it reaches a set water pressure. Though Pentair uses a bypass valve that is supposed to minimize this cycling, in reality, this RV pump cycles on and off frequently at lower water flow rates. This results in the rapid cycling of the electric RV water pump when you have a faucet or shower at a low water flow setting, causing a higher noise level.

Most of the RV pumps have a multi-chamber diaphragm design which over time can become corroded or calcified rendering them inoperable. Motor failure is the least common cause of pump failure, but the pump section itself can be a real cause for concern. Besides this general noise, one of the most obvious signs that a water pump is going out is if it makes excessive or unusual noise unlike the standard noise you normally hear.
