Style: 110V 5.5GPM 75PSI
We have this hooked up to a 300 gallon water tank at our cabin. It replaced a 12 volt RV water pump when we got our electrical hook up completed. It supplies water to our shower toilet and bathroom sink with no issues and plenty of pressure. This is our second summer with it and we have had no issues with it. It is a little noisy but all of this style pumps I have used are a little noisy.

I am tickled pink on how well this pump works. I have a rather poor water supply to my house so I stuck a water tank on the roof which fills slowly but gives me an acceptable flow of water, but nothing to write home about. I installed this pump on that water line coming from the tank, and I now have pressure like you can't believe. I still control the water flow at each faucet, but it's nice to know I can get a blast of water if I need it. I don't have an idea of how long this will last, so I just ordered another one to have as a spare. Edit: 8 oct 2024 This little guy is perfect, I'm thinking about adjusting the pressure down a bit - 70 lbs of water pressure is a little much even though I control it with my faucets. Main problem is the flex hoses on the shower head can't take the pressure. Nice problem to have.

This pump comes with such cheap clamps and attachments they break easily. All they clamps blew off and cost me to lose 350 gallons of water bc the pump doesn't have a shut off for theses situations except to unplug it if ur lucky enough be around to realize hose blew off when it happens. Pump should shut off when no water going through this pump doesn't just keeps running. Very dissatisfied do not use they attachments and clamps buy new ones bc the ones provided are a joke. The pump noise is kinda loud but bare able

I purchased several pumps for my cabin cruiser over the last few years using different brands. Had issues with them failing after a few months of use. I purchased this pump and after a few weeks, same thing happened. It just quit. I realized the problem was the pump was installed in the engine compartment where the temps are very high after running the engines for a while. Then when the pump ran for a period of time (like taking a shower), the extra heat from the pump combined with the engine room heat, burns out the pressure switch. So I moved the pump inside the cabin under the floor where temps are much cooler. Been running the pump hard for a few months now and it's still going strong. After running for long periods, I check the temps and the pump doesn't get hot at all (only slightly warm). I suspect this pump will last for several years now that it's not exposed to heat. Recommend installing in ambient temperatures. Very happy with pressure, volume, and quiet operation.

We bought 2 beautiful tiny cabins with 10 acres on a mountain. Love them! But the well water was terrible! The sodium and iron content off the charts! Ate up our new plumbing and fixtures. My husband designed and installed a water system with 2 - 250 gallon tanks and we haul in fresh water. We researched pumps and found that this RV system could take care of our needs - and it does. It was a bit noisy - but my husband mounted it to a heavy wooden box and then insulated it - now it is efficient and the noise reduction helped us to be totally pleased with this product!

I've been using this for several months, and while it’s functional and easy to use, there are a few drawbacks. Despite using Teflon tape, it eventually leaks due to the plastic threads connecting to metal. Initially, it was quiet, but it has started making noise over time. The power cord is shorter than I’d prefer, which limits placement options. Durability is also an issue, as I’ve noticed rust forming on the screws sooner than expected. Overall, it works well, but there are some design and durability concerns. It's not vale for money. Would suggest getting alternative options.
