Would you consider one of these? SHURflo EXTREME™ Smart Sensor™ 4.0 Fresh Water Pump
We have one and I really like it. The variable speed feature is what makes it a great pump. If you run the tap slowly the pump just ticks over slowly too so is very quiet, almost silent, especially appreciated at night when someone is sleeping. http://shurflo.com/marine-products/fresh-water-pumps/extreme-series-pumps/8-extreme-smart-sensor-4-0-fresh-water-pump-12vdc The Smart Sensor™ 4.0 is designed specifically for cruisers and midsize yachts. Delivering 4.0 GPM and pressure up to 50 PSI, this micro-controller based variable speed pump precisely monitors your system’s water pressure and adjusts the motor speed, eliminating the need for a pressure switch. SHURFLO® engineered the Smart Sensor™ 4.0 with a superior four-chamber design that incorporates large inlet and outlet passages to maximize water flow and efficiency, providing a “Just Like Home” shower and quiet operation.
