CRESTWAVE Fresh Water Pump 7 GPM / 70 PSI – 110V AC, 5-Chamber Self-Priming

Boost Your Water System with CRESTWAVE

The CrestWave Fresh Water Pump is a compact, reliable solution designed to bring steady pressure to your everyday water needs. Operating at 110V AC, it delivers a practical mix of flow (4-7 GPM) and pressure (70 PSI, adjustable 45-80 PSI) that can support showers, faucets, and irrigation in a range of settings. Its upgraded 5-chamber design aims for stable reflux and smoother operation, making it suitable for diverse installations—from RVs and homes to cisterns, marine vessels, greenhouses, and light industrial applications.

Real-world use often hinges on dependable performance and easy setup. This pump offers a self-priming lift of up to 10 ft with a maximum head of 157 ft, which helps maintain pressure even when water has to travel uphill or across longer runs. A built-in pressure switch enables automatic operation: the pump starts when water is demanded and stops when demand drops, potentially reducing manual checks and conserving energy where practical.
