## Customer Reviews

### ⭐⭐⭐⭐⭐ Change in Mounting the Unit Made a Difference
*by H***  on February 23, 2025*

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.
