DC HOUSE 12V RV Water Diaphragm Pump — Quiet On-Demand 3.5 GPM, 45 PSI

Meet the DC HOUSE 12V RV Water Diaphragm Pump

Designed for mobile living and off-grid setups, this pump delivers steady fresh water pressure with quiet operation. It fits neatly into standard RV, boat, and travel-trailer water lines, and it works well alongside solar power or other 12V systems. You’ll notice a compact footprint, smooth start-up, and reliable water delivery that supports daily routines on the road or at sea.

On-Demand Pressure With Adjustable Switch

Experience instant water when you open a tap thanks to the automatic pressure switch. The pump provides up to 3.5 GPM at a factory-set 45 PSI, with an adjustable switch to tailor the feel of your flow. This means you can dial in a comfortable balance between speed and quiet operation without constant pumping.

Prime, Pressure, and Reliability

The unit is self-priming up to 9.8 feet, simplifying installation even when the water source is a tank above the pump. It can lift water as high as 131 feet, which broadens installation options in taller rigs or elevated water tanks. A built-in thermal overload protector helps safeguard the motor during longer uses or when demand spikes.

Durable Diaphragm for Fresh Water

Engineered for fresh water applications, the diaphragm design promotes consistent pressure and dependable performance across daily tasks—handwashing, dish rinsing, and quick showers—while resisting wear from regular use.

Versatile for Marine and Off-Grid Use

Whether you’re on a boat, in a remote campsite, or living off the grid, this pump powers essential water fixtures—faucets, showers, and small water systems—without needing complex plumbing upgrades. Its 12V DC compatibility supports battery-based or solar power configurations common in mobile setups.
