Shurflo 4048-153 High Flow RV Fresh Water 12V Pump Complete Kit

This pump is designed for intermittent duty. The pump operates normally up to about 30-psi, where a spring-loaded by-pass valve opens, allowing flow back from the output side to the input side, providing smooth, steady flow with virtually no cycling, all the way down to a trickle. As a faucet is opened back up, the pressure will drop, the by-pass will close and full flow is again obtained. This allows good flow, even with today's restrictive showers and pullout sprayer faucets. Performance will vary, of course, depending on the voltage to the pump; lower voltage = lower flow, higher voltage = higher flow.

This pump is the replacement for the 4900 and 5900 Shurflo Pumps. Equipped with an automatic thermal overload protection. A built-in check valve prevents backflow.
