Buying Guide

Match pump flow and pressure to your fixtures

Choose a pump with GPM and PSI suitable for your faucets and shower—3.0–3.5 GPM and 40–55 PSI suits most RV systems

Prefer diaphragm pumps for RV use

Diaphragm pumps self-prime and handle intermittent flow well, reducing cavitation and protecting onboard plumbing

Consider pre-pressurized accumulator tanks

Accumulator tanks smooth pulsation and reduce pump cycling for quieter operation and longer pump life

Check voltage and wiring compatibility

Confirm the pump runs on your RV’s 12V system and that wiring, fuses, and connectors match installation requirements

Look for built-in strainers and serviceability

Integrated inlet strainers and modular components make maintenance easier and protect pumps from debris and wear
