Review: So far so good, off-grid water application - So far this has performed well over the past few weeks of initial use. We have an off-grid property that has a well pump but no plumbing (well tank or pressure switch), so we didn't want to stress the well pump trying to use it on-demand for various uses. So, we put in a holding tank and connected everything with drinking water rated garden hose, and GHT - 1/2" NPT adapters. These adapters are widely available on desertcart (search GHT or garden hose thread to 1/2" NPT or pipe thread). The pump pulls water from the holding tank and goes past a small accumulator (This is recommended to smooth out the pressure spikes / drops in the lines as water is started/stopped frequently and slightly reduces charging cycles -search for seaflow brand), and goes out to another garden hose valve with various connections for various purposes (irrigation, outdoor shower, utility sink). I would much rather keep one of these on the shelf for 75 bucks in case it burns out than risk stressing a well pump 200' below the ground, that would be a substantial cost and effort to replace. Overall happy with the unit, some of the fittings that come with it seem a little flimsy, I used all brass fittings with Teflon tape and so far leak-free. I added an in-line 120V switch mounted next to it so I can easily turn it on and off. Review: Water pressure pump - Quick transaction. Great quality. Used this to winterize my RV. Worked great. ## Features - COMPLETE KIT INCLUDES EVERYTHING YOU NEED: (1)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 - EAST TO USE: The Water Pump Can Simply Plug into Any Standard Wall Socket in The House, a Great Water Pump for Home - FULLY AUTOMATIC OPERATION WITH PRESSURE SWITCH: This RV Water 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 Water Pump for RV, Camper, Boat, Sprinkler, Faucet, car washing, yacht, garden, kitchen bathroom and long-distance pumping in the courtyard. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BF9G3J86 | | Best Sellers Rank | #567,334 in Automotive ( See Top 100 in Automotive ) #270 in RV Water Pumps & Accessories | | Brand | wassermann | | Brand Name | wassermann | | Color | ['Gray'] | | Customer Reviews | 4.0 out of 5 stars 182 Reviews | | Flow Rate | 4 Gallons Per Minute | | Included Components | 1* Filter Out Debris 2*Clamps, 1*1/2" Male Thread Hose Adptor, 1*Use Manual, 2*1/2" Barbed Hose Adaptors, rv pump | | Item Dimensions L x W x H | 8.78"L x 5.12"W x 4.86"H | | Item Type Name | Water preesure pump | | Item Weight | 6.7 Pounds | | Manufacturer | wassermann | | Manufacturer Part Number | 3WDP4-45-115V | | Material | Plastic | | Material Type | Plastic | | Maximum Lifting Height | 98 Feet | | Model Number | RV water pump | | Power Source | Corded Electric | | Product Dimensions | 8.78"L x 5.12"W x 4.86"H | | Product Style | 3WDP4-45-115 | | Style | 3WDP4-45-115 | | Unit Count | 1.0 Count | | Voltage | 110 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 Water Pumps, Fresh Water Pump for RV Kitchen Barthroom Marine Yacht Garden Diaphragm Pump Self Priming Water Pump 4GPM 45psi - Image 1](https://m.media-amazon.com/images/I/71zsfASiibL.jpg) ![WASSERMANN RV Water Pumps, Fresh Water Pump for RV Kitchen Barthroom Marine Yacht Garden Diaphragm Pump Self Priming Water Pump 4GPM 45psi - Image 2](https://m.media-amazon.com/images/I/81iEWG+PswL.jpg) ![WASSERMANN RV Water Pumps, Fresh Water Pump for RV Kitchen Barthroom Marine Yacht Garden Diaphragm Pump Self Priming Water Pump 4GPM 45psi - Image 3](https://m.media-amazon.com/images/I/81hrTnfRJgL.jpg) ![WASSERMANN RV Water Pumps, Fresh Water Pump for RV Kitchen Barthroom Marine Yacht Garden Diaphragm Pump Self Priming Water Pump 4GPM 45psi - Image 4](https://m.media-amazon.com/images/I/81njjoGKHNL.jpg) ![WASSERMANN RV Water Pumps, Fresh Water Pump for RV Kitchen Barthroom Marine Yacht Garden Diaphragm Pump Self Priming Water Pump 4GPM 45psi - Image 5](https://m.media-amazon.com/images/I/81YZG+GKXYL.jpg) ## 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 ### ⭐⭐⭐⭐⭐ So far so good, off-grid water application *by B***D on June 9, 2024* So far this has performed well over the past few weeks of initial use.

Used this to winterize my RV. Worked great. ### ⭐⭐⭐⭐ Leaked out of Every Seam After 1.5 Months *by M***E on July 17, 2024* The unit worked great until AFTER the return window (a month and a half). It started leaking out of every seam, and water was coming out of where the electrical cord enters the unit. I used it attached to a garden hose to pump water up to a sprinkler on a hill. My husband took it apart and back together to see if it would not leak, but no it did not help. But....now it's broken and I had to buy a new one from Harbor Freight. UPDATE: The seller promptly offered to refund my order. Great customer service. ## Frequently Bought Together - WASSERMANN Water Pressure Diaphragm Pump 115V AC 4.0 GPM 45PSI,Self-priming Booster Pump with Power Plug, for Kitchen Bathroom RV Marine, Yacht Garden - DERNORD PVC Tubing 3/8"ID X 1/2"OD Flexible Clear Vinyl Hose 10 Feet for Food Grade - Homebrewers Outpost - D1262 Pluto Beverage Gun - ABS --- ## 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.tn/products/500084473-wassermann-rv-water-pumps-fresh-water-pump-for-rv-kitchen](https://www.desertcart.tn/products/500084473-wassermann-rv-water-pumps-fresh-water-pump-for-rv-kitchen) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-23*
