Simple and easy Review: Works Great - Great Price as Well - Works great. Had to replace pump on used travel trailer we purchased. Trip was rough without the pump. Ordered it when I was at destination. Put it on before heading home and it worked great. It is a little more powerful than the one it replaced. Only problem would be is using more water than you wanted to by turning the tap open more than necessary. Great improvement actually a fine upgrade.

This pump is 4 gallons per minute. ## 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 | | Best Sellers Rank | #2,221 in Automotive ( See Top 100 in Automotive ) #1 in RV Water Pumps & Accessories | | Brand | wassermann | | Brand Name | wassermann | | Color | White02 | | Customer Reviews | 4.4 out of 5 stars 1,421 Reviews | | Flow Rate | 4 gpm | | Included Components | pump | | Item Dimensions L x W x H | 8.15"L x 5.12"W x 4.86"H | | Item Weight | 4.2 pounds | | Manufacturer | WASSERMANN | | Manufacturer Part Number | WDPC | | Manufacturer Warranty Description | 2year | | Material | Plastic | | Material Type | Plastic | | Maximum Lifting Height | 98 feet | | Model Number | 3WDP4-45-12V | | Number of Items | 6 | | Power Source | Battery Powered | | Product Dimensions | 8.15"L x 5.12"W x 4.86"H | | Product Style | 3WDP4-45-12V | | Specific Uses For Product | Traveling, Camping, Road Trips, Cruises | | Style | 3WDP4-45-12V | | Unit Count | 1 Count | | Voltage | 12 volts | ## Product Details - **Brand:** wassermann - **Color:** White02 - **Item Weight:** 4.2 pounds - **Material:** Plastic - **Maximum Flow Rate:** 4 gpm - **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 ![3WDP4-45-12V - Image 1](https://m.media-amazon.com/images/I/71QeYqWbRdL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Decent little pump *by A***S on August 24, 2026* Easy to wire up and supplies adequate water pressure to a few small fixtures.

A little different wiring and mounting, but pretty close. It is a little louder than I would like, but the pressure is amazing and is much more smooth than the old one. Highly recommended. ## Frequently Bought Together - WASSERMANN RV Pump, 12V Self-priming RV Water Pressure Pump 4.0GPM 45PSI with Pressure Switch, for RV Marine Camping Yacht Garden - SEAFLO Accumulator Tank Water Pump Flow Control with Internal Bladder - 125 PSI, 23.5 oz (0.75 L) | Reduces Pump Cycling and Smooths Water Flow for Marine, RV, and Off-Grid Systems - SHURFLO (255-313) 1/2" Twist-On Pipe Strainer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/498044165-3wdp4-45-12v](https://www.desertcart.it/products/498044165-3wdp4-45-12v) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-09-28*
