Before You Buy: Not Sure Which Power Source to Choose?

Choose 12V DC for battery-powered RVs, mobile setups, or off-grid use. Choose 110V AC when a household outlet or RV shore-power connection is consistently available.

The kit comes fully assembled, including 3 hose adapters, 2 strainers, and Teflon tape, making it the ideal solution for both professional and DIY water pressure installations. Simplify your setup with this all-in-one water pump package.

  • Whisper-Quiet Operation: Designed for minimal noise, this RV water pump features anti-vibration rubber feet and a shock-resistant iron plate, reducing system noise to below 45 dB. Whether you're in a quiet residential area, RV park, or onboard a boat, this pump ensures a peaceful environment by reducing unwanted pump cycling and noise disruptions.

  • Consistent Water Flow with Stable Pressure: Experience smooth and reliable water flow with our 5-chamber RV water diaphragm pump. It supports a high water flow rate of up to 7 GPM while the accumulator tank maintains steady water pressure, even when water demand fluctuates. This setup minimizes surges and pressure drops that could damage plumbing fixtures or appliances, ensuring a seamless user experience.

  • Prolonged Pump Lifespan: The inclusion of the accumulator tank and intelligent design helps reduce excessive pump cycling. By minimizing the wear and tear on the RV water pump and connected components, you’ll enjoy fewer maintenance issues and extend the lifespan of your system, saving you both time and money on repairs.

  • Enhanced Protection with Dry Run & Thermal Overload Safety: This RV water pump and accumulator tank kit offers dry run protection, allowing the pump to operate for short periods without water, reducing the risk of motor damage. Additionally, the built-in thermal overload protection safeguards the motor from overheating, enhancing safety and extending the overall lifespan of the pump.

Important Purchase and Installation Notice

Before installing and operating your new RV fresh water pump (including all models within the Kohree RV water pump series), please ensure that a proper strainer/filter has been installed. This component is essential to prevent sediment and impurities from entering the pump mechanism, which can cause internal damage or lead to complete operational failure.

Please be advised that our warranty and return policy do not cover products that become non-functional due to the absence of a correctly installed strainer. By purchasing and using this product, you acknowledge and agree to these terms and conditions.

Strong flow, quieter than most

Really like the KOHREE Water Pump and Accumulator Tank System. Comes pre-mounted on a plate, ready for straightforward integration into your water setup with simple 12 or 24 volt wiring. Includes hose fittings and a clear, easy-to-clean debris filter. The pump delivers solid water flow and operates quieter than most. Features auto shutoff functionality. Appears all components are replaceable according to the manual. Includes helpful troubleshooting diagrams and part images for ordering replacements. The accumulator tank provides instant pressurized water. Installation was quick-just bolt in place and connect water lines. Basic 12 volt wiring suited my setup. Overall footprint for plate and unit measures 15" length by 13?" width. Instruction manual could be clearer, but with basic plumbing and electrical skills, installation goes smoothly using minimal tools. Definitely recommend the KOHREE system for anyone replacing their RV, van, or boat water pump setup.

Nice pump

Mounted this on my cabover pop-up camper for use with the tankless water heater for showers, works really well. Replumbed using 1/2" PEX to improve flow.

Rugged diaphragm pump on rubber feet

Had to replace multiple freshwater pumps in my motorhome over the years, so I picked up this Kohree diaphragm freshwater pump as a spare-since they tend to fail or start leaking when you're out camping.

One feature that stood out immediately was the all-rubber mounting. Makes a big difference in how quiet the pump runs in your RV or boat. Most come on metal brackets with tiny rubber grommets, which don't do much to reduce vibration or noise.

This pump just feels like a premium-quality product, and I'd put it right up there with well-known names like Pentair and Shurflo. Haven't installed it yet, but I hooked it up to hoses and tested it with a 12V battery-it worked flawlessly. It's self-priming, and while pressure is adjustable, the rated 45 PSI and 3.3 GPM are ideal for most RV or boat setups.

Fittings are the standard 1" MNPT type commonly found on these pumps, so they should match your existing setup. It also includes barbed fittings for 1/2" PEX or hose if you're starting fresh, plus a cleanable mesh pre-filter.

Highly recommend this pump-great value for the quality you're getting. ?????

Perfect for the overland trailer

Picked up this water pump for my overland camping trailer. Plan to connect it to a 12V LiPo battery that's solar-charged, using it to supply my propane water heater and shower. While waiting on a few remaining parts, I gave the pump a test run. It started right up and actually had a bit of water inside right out of the box. Likely from factory testing, as there's no indication it was previously used.

I am using it to supply water for my cabin. As soon as I install it I will reach out.

Never received the inital package after they sent it to somewhere.. and have heard nothing about it being resent or a refund- *** Update ***
After sending another email explaining that the issue was not my fault with the shipper not delivering the product and that I had paid for a product and. It was not delivered, I finally got an email and they sent a replacement that I did receive.
The product itself was exactly as advertised and shipped securely.
I hate it took escalating emails for it to be handled, But in the end they did the right thing and I received the product.
Five stars for the actual product
3 Stars for the customer service
2 stars for the experience.

Overall I give it a 4 all in all. Had it been handled Immediately it would have been 5 stars.

Oddball setup, still fits

Not using the Kohree RV Fresh Water Pump 3.3GPM 45PSI 12V DC in an RV, but it's performing excellent. Installed it on my kayak trailer. Run a pickup line with a filter on the end into the water at the ramp before leaving. Have a hose sprayer on the outside, using it to rinse down the kayaks right at the ramp.

Dropped in to replace a dead one-love it

My old water pump in the travel trailer finally gave out. Never enjoyed using it-the pressure and flow were awful, and I wasn't upset to see it fail. Installed this one and couldn't be happier. The pressure and flow are far superior compared to the original pump that came with the trailer. Only wish I'd upgraded sooner.

Runs like a top

Used this for a solar-powered garden hose drawing from a 500-gallon tank in the middle of my fields. Performs well. Since then made the setup portable.

Boat-build project helper

Not a large boat-just an 8.2-foot by 28-foot trailerable size-and using some unconventional building methods. Which is exactly why this pump suits my setup. There's an on-demand hot water unit serving both the galley sink and the shower across the shared wall. RVs and small boats have a lot in common, especially maximizing space and making systems multi-functional. This pump handles both the galley and head-only one sink is needed since they're close together, plus the shower. Learning most connections as I go, which is part of the process. Once complete, if repairs are needed, I'll understand the entire system and handle them myself. Testing the pump-with the 60-gallon bladder planned for under the floorboards-alongside the on-demand heater gave me confidence the whole setup will perform as intended.

Handy little off-grid water mover

Currently using this as a backup 12V pump to supply water during power outages. Enables filling the tank using just a basic battery. Unlike typical transfer pumps, this one delivers up to 45 PSI, sufficient for shower or sink use when providing off-grid water pressure.

Dave

Does it have to mounted on the supplied plate, and is the pressure adjustable. Is 70psi to high for an Rv that only recommends 40 psi water inlet?

Can this be connected to the city line?
