Works great! - Installed my new Kohree RV Water Pump today, and it works great! I like the mounting platform with the screw-down connectors. This pump provides a quieter pump operation than the old, OEM pump, which was only 3 GPM, with no accumulator tank. The 5.5 GPM pump provides better pressure and flow, with the accumulator tank providing some “shock absorption,” so if someone is taking a shower, and another person starts washing dishes, “the shock” of the water turning on and off for the person in the shower is not felt. Overall very pleased with the item, the price, and the quicker-than-expected delivery. Review: Change in Mounting the Unit Made a Difference - At first I had the unit flat on the ground horizontally for about 2 to 3 weeks. We use it daily everyday. It did okay but it would act like it lost the prime and would run longer than it should while priming itself and building pressure again. I got tired of that happening so I mounted it vertically as the picture shows. I did do some plumbing with the shark bite fittings and added a check valve just in case. We have been using it without a single problem or loosing prime now for a few weeks. It isn’t as loud as the original pump and the accumulator tank helps to reduce cycles of the pump coming on. It is mounted inside our 5th wheel storage cabinet so you hear it but it’s not a big deal. My friend has the same one mounted in his 5th wheel near the under storage area and you can barely hear it run when it’s quiet inside the trailer. At this point I’m happy with the pump and the pressure it delivers because we rely on it daily while living off grid. It’s great for showers and handles the vanity faucet and kitchen faucet with ease. I have turned the kitchen faucet on while my wife was using the shower and didn’t hear any yells or screams due to poor water pressure. If I would have left the pump alone and not tried to improve the plumbing situation, I’m sure I wouldn’t be happy with the pump at all. But RV plumbing isn’t all that good from the factory and can be easily improved by common sense and some know how or a friend that knows what they are doing and can help to improve the situation of RV plumbing. I would recommend this water pump. ## Features - 【Features】This set consists of a 4 chamber diaphragm pump 55 PSI with 5.5 GPM water flow, and a 0.75L pre-pressurized accumulator tank, 2 hose adapters. A fully assembled pressure set that simplifies the installation of water pressure systems for both the professional and amateur installer - 【Quiet Operation】Equipped with anti-vibration rubber feet and shock-proof iron plate, this set can reduce noise of your water system, operating volume below 45 DB. It can also reduce water pump kicking on, provide a more quiet and pleasant environment, especially in residential or recreational settings like RVs and boats - 【Smooth Water Flow】Kohree 4-chamber RV Water Diaphragm Pump transfers high volume water flow to 5.5 GPM. And the accumulator tank acts as a buffer, providing a steady water pressure even when the demand fluctuates, ensuring smoother water flow for a consistent user experience. It also prevents surges or drops in pressure that can be potentially damaging to fixtures and appliances - 【Extended Pump Lifespan】By reducing pump cycling, the system minimizes wear and tear on both the pump and other components, leading to fewer maintenance issues and longer service intervals - 【Run Dry & Thermal Overload Protection】Kohree RV Water Pump can run dry for a short period time, reducing the risk of motor burnout. The thermal overload protection function of the motor makes our products safer and can be used longer ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D3DXCRKS | | Best Sellers Rank | #41,837 in Automotive ( See Top 100 in Automotive ) #44 in RV Water Pumps & Accessories | | Brand | Kohree | | Brand Name | Kohree | | Color | Black | | Customer Reviews | 4.2 out of 5 stars 92 Reviews | | Flow Rate | 5.5 Gallons Per Minute | | Included Components | RV Water Pump and Accumulator Tank System | | Item Type Name | RV Water Pump and Accumulator Tank System | | Manufacturer | Kohree | | Material | Stainless Steel or Polyvinyl Chloride | | Material Type | Stainless Steel or Polyvinyl Chloride | | Maximum Flow Rate | 5.5 Gallons Per Minute | | Model Number | HY1734 | | Power Source | Corded Electric | | Product Style | 5.5GPM 55PSI Water Pump with Accumulator Tank | | Style | 5.5GPM 55PSI Water Pump with Accumulator Tank | ## Product Details - **Brand:** Kohree - **Color:** Black - **Manufacturer:** Kohree - **Material:** Stainless Steel or Polyvinyl Chloride - **Maximum Flow Rate:** 5.5 Gallons Per Minute - **Number of Items:** 3 - **Number of Packs:** 1 - **Power Source:** Corded Electric - **Style:** 5.5GPM 55PSI Water Pump with Accumulator Tank ## Images ![RV Water Pump 12V DC 5.5GPM 55PSI and 0.75L 125PSI Pre-Pressurized Accumulator Tank, Quiet RV Water Pump and Accumulator Tank System for RV Camping, Boat, Kitchen, Bathroom - Image 1](https://m.media-amazon.com/images/I/718lbFihOkL.jpg) ![RV Water Pump 12V DC 5.5GPM 55PSI and 0.75L 125PSI Pre-Pressurized Accumulator Tank, Quiet RV Water Pump and Accumulator Tank System for RV Camping, Boat, Kitchen, Bathroom - Image 2](https://m.media-amazon.com/images/I/71rtj96KGqL.jpg) ![RV Water Pump 12V DC 5.5GPM 55PSI and 0.75L 125PSI Pre-Pressurized Accumulator Tank, Quiet RV Water Pump and Accumulator Tank System for RV Camping, Boat, Kitchen, Bathroom - Image 3](https://m.media-amazon.com/images/I/71MqUZllFzL.jpg) ![RV Water Pump 12V DC 5.5GPM 55PSI and 0.75L 125PSI Pre-Pressurized Accumulator Tank, Quiet RV Water Pump and Accumulator Tank System for RV Camping, Boat, Kitchen, Bathroom - Image 4](https://m.media-amazon.com/images/I/71ZNlSHdfTL.jpg) ![RV Water Pump 12V DC 5.5GPM 55PSI and 0.75L 125PSI Pre-Pressurized Accumulator Tank, Quiet RV Water Pump and Accumulator Tank System for RV Camping, Boat, Kitchen, Bathroom - Image 5](https://m.media-amazon.com/images/I/71TJaL+BguL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How it works？** A: 1.

Better water flow with much less noise. ## Frequently Bought Together - Kohree RV Water Pump 12V DC 5.5GPM 55PSI and 0.75L 125PSI Pre-Pressurized Accumulator Tank, Quiet RV Water Pump and Accumulator Tank System for RV Camping, Boat, Kitchen, Bathroom - iCrimp PEX Clamp Tool Kit for 3/8-in, 1/2-in, 3/4-in, 1-in PEX Clamp Cinch & Removal, c/w 1/2''(20 Pack) and 3/4''(10 Pack) PEX Clamp Rings, PEX Tubing Cutter - Pex Fittings 1/2 Inch, 36 PCS SUNGATOR 1/2 Inch Pex Fittings Set, 12 Each PEX Elbow Tee Coupling, 1/2" Pex Fittings For Pex Pipe, No Lead Brass, ASTM F1807 --- ## 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.co.th/products/655971387-rv-water-pump-12v-dc-5-5gpm-55psi-and-0](https://www.desertcart.co.th/products/655971387-rv-water-pump-12v-dc-5-5gpm-55psi-and-0) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-02*
