wassermann 115V RV Water Pump — 4.0 GPM 45 PSI Self‑Priming Diaphragm with Pressure Switch and Inline Filter

This compact, plug‑in water pump is built for mobile and small‑scale fixed installations where steady water pressure matters. Designed for RVs, campers, yachts, garden use and even as a home booster, the 115V electric motor eliminates the need for special wiring. The pump ships as a complete kit with hose adaptors, a debris filter, and a user manual so you can install and run it quickly.

How does this pump maintain steady water flow for sinks and showers?

The pump uses a diaphragm design and an integrated pressure switch to sense demand and deliver consistent pressure. When you open a faucet the pump starts automatically, and it stops when the flow ceases, protecting the motor and saving energy. Its 4.0 GPM flow rate and 45 PSI cut‑in/out setting are tuned for typical RV and marine fixtures.

• Diaphragm mechanism for smooth, pulsation‑reduced flow
• Auto start/stop via pressure switch for hands‑free operation
• Rated 4.0 GPM flow and nominal 45 PSI for reliable fixture performance

What makes installation straightforward for non‑technicians?

This pump is a 115V plug‑in unit intended for easy setup without special wiring or a dedicated breaker. The kit includes 1/2" barbed and male threaded hose adaptors plus a removable inline debris filter to guard against particles. Mounting points and the included manual guide basic plumbing and electrical connections so you can install it in minutes.

• Standard 115V plug — works with household outlets

How durable and versatile is the pump for outdoor and marine use?

The pump is constructed for frequent starts and stops and for use across a variety of environments — from RV holding tanks to onboard fresh water systems. Materials and seals are selected to withstand normal exposure to fresh water and intermittent outdoor conditions. It’s suited for light irrigation, car washing, and other tasks where moderate pressure and flow are required.

• Suitable for RVs, boats, yachts, gardens, and small boosters
• Works for short‑distance pumping and common outdoor chores

What safety and maintenance steps should owners follow?

Follow the included manual for proper mounting orientation, hose connections and strainer placement to avoid dry‑running and debris damage. Periodically inspect the inline filter and hoses, and winterize the pump in freezing climates by draining or storing it indoors. Always use a properly grounded outlet and avoid submerging the motor housing.

• Check and clean the debris filter regularly to maintain flow
• Drain or remove pump before freezing temperatures
• Use grounded power source and follow basic electrical safety
