DC HOUSE RV Water Booster Pump 110V — 5.5 GPM, 70 PSI On-Demand Self-Priming Diaphragm

DC HOUSE 110V RV Water Booster Transfer Pump is a plug-and-play diaphragm pump that provides up to 5.5 GPM and boosts water pressure to 70 PSI for RVs, rain barrels, garden use, and light transfer jobs.

This compact 110V unit combines an on-demand pressure switch with a self-priming diaphragm design to supply steady water flow where household pressure is lacking. Designed for portable and semi-permanent applications, it draws from tanks or barrels, turns on when a faucet opens, and shuts off automatically at the preset pressure. Built-in thermal protection and an adjustable pressure setting make it adaptable to a range of outdoor and recreational uses.

How does this pump improve water pressure for an RV or campsite?

The pump raises low supply pressure quickly and maintains consistent flow for sinks, showers, and small appliances. It activates automatically when you open a tap, delivering reliable water delivery without manual switches. The diaphragm mechanism helps tolerate varying water sources and debris better than some impeller pumps.

• Delivers up to 5.5 gallons per minute for multiple fixtures
• Automatic pressure switch turns pump on and off with demand
• Shuts off near the 70 PSI preset to prevent overpressurizing

Can I use this pump to move water from a rain barrel or storage tank?

Yes — the pump is self-priming and can lift water from shallow sources, making it suitable for rain barrels, cisterns, and storage tanks. Its suction capability and maximum head allow you to transfer water uphill or fill a garden hose for irrigation tasks. The pump’s diaphragm construction helps manage varied water quality often found in outdoor storage.

• Self-primes up to 9.8 feet of vertical suction
• 131-foot maximum head to push water to elevated areas
• Works with hoses and standard garden fittings for easy hookup

What safety and durability features should I expect?

The motor includes thermal overload protection that stops the pump if it runs hot, reducing risk of damage from extended operation. The diaphragm design is durable for frequent cycling and tolerates intermittent dry running better than some designs. The pressure switch is adjustable so you can fine-tune cut-in and cut-out pressure to suit your setup.

• Automatic thermal protection prevents motor overheating
• Long-life diaphragm for consistent pumping performance
• Adjustable pressure switch for custom pressure settings

How easy is installation and everyday operation?

Installation is straightforward: plug the unit into any standard 110V outlet and connect inlet and outlet hoses or fittings. No hardwiring is necessary for most installs, and the on-demand switch automates operation. This makes it a practical choice for seasonal setups or temporary water transfer tasks.

• 110V plug-and-play power — no electrician required for typical installs
• Simple hose or threaded connections for inlet and outlet
• Low-maintenance design ideal for occasional and frequent use

Who this is for: The DC HOUSE 110V RV Water Booster Transfer Pump is suited for RV owners and weekend campers who need dependable tap pressure, gardeners and landscapers moving water from barrels or tanks, and homeowners wanting a portable, adjustable pump for sprinklers or utility tasks. It’s also a good fit for anyone who wants a plug-and-play solution with thermal protection and the flexibility to handle different outdoor water sources.
