wassermann 12V RV Water Pump 4.0 GPM 45 PSI — Self-Priming Fresh Water Pump Kit with Filter

The WASSERMANN 12V RV Pump is a self-priming, 4.0 GPM fresh water pressure pump with a 45 PSI pressure switch that delivers automatic, reliable water flow for RVs, boats, and campsites.

If you need steady water pressure from a 12-volt system, this pump is built to supply sinks, showers, and onboard plumbing without fuss. The unit arrives as a complete kit with hose adaptors and a debris filter, runs from any 12V battery or cigarette-socket, and shuts off automatically with the integrated pressure switch. Designed for mobility and repeated use, its corrosion-resistant components and short-time dry-run capability make it a practical choice for travel and marine environments.

How does the WASSERMANN pump perform for everyday RV water use?

This pump produces up to 4.0 gallons per minute and maintains about 45 PSI, giving consistent flow for washing, cooking, and quick showers. The pressure switch provides on-demand start/stop to avoid the need for manual intervention.

• Maximum flow: 4.0 GPM for steady supply to fixtures
• Pressure setting: ~45 PSI for comfortable water delivery
• Automatic operation: pressure switch starts and stops the motor
• Self-priming: ready to draw water without complex setup

Can I power the pump from typical vehicle or marine electrical systems?

The pump uses a 12V DC motor and can be connected directly to a 12-volt battery or plugged into a cigarette lighter socket where wiring and connectors allow. That flexibility lets you install it in RVs, boats, and trailers without special power converters.

• 12V DC compatible with standard vehicle batteries
• Cigarette-socket friendly for quick temporary power
• Low-voltage operation reduces electrical system complexity
• Includes clear manual for safe wiring and fuse recommendations
