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. Review: Works like a champ - I created a transfer pump to run off 12 volt to move water into my RV from a storage tank. This pump moved plenty of water and has yet to cause any issues. It has multiple times transferred 100 gallons of water in one sitting without issue. So far I have been impressed with the quality. I'm building my next transfer box for a buddy and I will be making some changes. I will not be changing this pump though, it's been a rock star. ## 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 | #2,258 in Automotive ( See Top 100 in Automotive ) #2 in RV Water Pumps & Accessories | | Brand Name | wassermann | | Color | Black,grey | | Customer Reviews | 4.5 4.5 out of 5 stars (811) | | Flow Rate | 4 Gallons Per Minute | | Included Components | 1*PUMP, 4*adapters | | Item Dimensions L x W x H | 8.15"L x 5.12"W x 4.86"H | | Item Weight | 4.17 Pounds | | Manufacturer | WASSERMANN | | Material Type | Plastic | | Maximum Lifting Height | 98 Feet | | Model Number | WDPC | | Power Source | Battery Powered | | Product 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 ![WASSERMANN 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) ![WASSERMANN 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 2](https://m.media-amazon.com/images/I/611fgjttYqL.jpg) ![WASSERMANN 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 3](https://m.media-amazon.com/images/I/71qVGk5ZFqL.jpg) ![WASSERMANN 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 4](https://m.media-amazon.com/images/I/81JtvJfimpL.jpg) ![WASSERMANN 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 5](https://m.media-amazon.com/images/I/81deP4LwMfL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: can this pump be used with a pressure washer? I have a 275 gallon water tank and need water pumped to the pressure washer.** A: Anything less then I believe its 55 pounds of pressure going to the pump and it turns on automatically. So if water comes out of your tank at a lower pressure the pump should sense it and turn on and pump water out at 55 lbs. **Q: Can this pump have bleach run through it without corroding?** A: Limit it to the 2-3ppm chlorine concentration of a city water supply. **Q: Will this work in a home that just has low pressure on top of the hill of the city to supply a house? Showers, sinks, toilets...** A: No **Q: What type of male threads are on the pump's outlets IT IS NOT NPT!!! are they GHT (Garden hose threads )? how to adapt them to USA NPT?** A: Comes with adapters and I hooked up to pex plumbing. I used pex pipe and crimps. You can buy adapters for pex or anything you need on Amazon just search for it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great water pump!! *by E***N on January 27, 2026* 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.
