Review: Great water pump!! - Im a RV Technician and I use this pump for water testing, fresh system flush, winterizations, works great have it running off a Milwaukee 12v battery with one of them adapters. This thing works great with water, antifreeze, this pump puts out plenty of flow and awesome pressure, shuts off when pressure is built, comes with a bunch of fittings and the strainer, can't beat the price and how much of a workhorse it is! Highly recommend for rvs and other uses such as off grid, or for liquid transfer. ## Features - COMPLETE KIT INCLUDES EVERYTHING YOU NEED: (1)12V RV Water Pump, (2)1/2" Barbed Hose Adaptors, (1)1/2" Male Thread Hose Adptor, (1)Filter Out Debris, (1)User Manual - POWERFUL & EFFICIENT PERFORMANCE: Delivers a strong water flow of up to 4 gallons per minute (GPM) with a consistent 45 PSI pressure setting for reliable use in your RV or camper. - VERSATILE 12V DC POWER OPTIONS: The Electric RV Water Pump is Designed with a 12V DC Motor, Can be Powered By Any 12 Volt Battery or Mount to Any Cigarette Lighter Socket in the RV and Camper. - FULLY AUTOMATIC OPERATION WITH PRESSURE SWITCH: This RV Water Pump Works with a Pressure switch, the pump starts automatically when you turn on the tap and shuts off when you close it, providing a hassle-free, hands-off water system. - DURABLE & RELIABLE FOR DEMANDING USE: It is an Ideal 12V RV Pressure Pump for RV and Camper, features a self-priming design, corrosion-resistant construction, and a short time safe dry-run capability for long-lasting performance in various conditions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BFB1FMKV | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #3,987 in Automotive ( See Top 100 in Automotive ) #3 in RV Water Pumps & Accessories | | Brand | wassermann | | Color | Black,grey | | Customer Reviews | 4.4 4.4 out of 5 stars (1,323) | | Date First Available | September 14, 2022 | | Included Components | 1*PUMP, 4*adapters | | Item Weight | 4.17 pounds | | Item model number | WDPC | | Manufacturer | WASSERMANN | | Material | Plastic | | Maximum Flow Rate | 4 Gallons Per Minute | | Maximum Lifting Height | 98 Feet | | Power Source | Battery Powered | | Product Dimensions | 8.15"L x 5.12"W x 4.86"H | | Size | 3WDP4-45-12V | | Style | 3WDP4-45-12V | | Voltage | 12 Volts | ## Product Details - **Brand:** wassermann - **Color:** Black,grey - **Item Weight:** 4.17 Pounds - **Material:** Plastic - **Maximum Flow Rate:** 4 Gallons Per Minute - **Maximum Lifting Height:** 98 Feet - **Power Source:** Battery Powered - **Product Dimensions:** 8.15"L x 5.12"W x 4.86"H - **Style:** 3WDP4-45-12V - **Voltage:** 12 Volts ## Images ![RV Pump, 12V Self-priming RV Water Pressure Pump 4.0GPM 45PSI with Pressure Switch, for RV Marine Camping Yacht Garden, 12Volt DC Fresh Water Pumps RV Water Pump 2088-554-144 Replacement - Image 1](https://m.media-amazon.com/images/I/71V+iYKgeEL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable RV Water Pump Upgrade *by E***S on October 22, 2025* Embarking on RV adventures is now a breeze thanks to the incredible WASSERMANN RV Water Pump.
