The Onsen 3.0 RV / Marine Diaphragm 12V Water Pump is designed to bring water pressure to cabins, boats, RV fixtures and tankless water heaters.
Featuring noise absorbing mounts for quiet operation and factory calibrated for seamless installation with portable tankless water heaters such as the Onsen 5L and 10L, the 3.0 GPM, 12V Onsen pump is an integral part of any off-grid water installation.
Working in combination with the pump, the Onsen 1.0L Accumulator Tank ensures even water flow by acting as a pressure buffer for the pump, which helps to extend the life of the pump, decreases power consumption, and reduces plumbing noise (pipe hammer).
