Your RV or boat water pressure drops the second you open two taps, and the pump cycles on and off every thirty seconds like it's having a fit. The Seaflo RV Supreme Auto fixes both. Quad-chamber diaphragm with an internal bypass keeps flow steady at 11.3 L/min and 55 PSI without hammering the system. Built-in pressure switch means it kicks on when you open a tap and shuts off when you close it — no accumulator tank, no external switch to wire up. Self-priming and safe to run dry, so a low tank level won't torch the diaphragm. 5-minutes-on / 10-minutes-off duty cycle protects the motor on long runs. Quick 1/2" screw-on fittings make the install a ten-minute job. Suited for boats, RVs, and remote cabin water systems. $169 RRP. Add to cart
