Overall I like this upgrade. The only issue I had with mine is that the pressure switch seemed to be set too high. When I first installed it, I switched it on started testing things. Everything was going good, so I left the pump on to see if I had any leaks for a while. I came back about an hour later and I couldn't touch the pump it was so hot. It also wouldn't run at that point when I turned on a faucet. It turned out that the pressure switch was set too high, and even 12 volts from the converter in my RV couldn't supply enough juice over 12a WG wire to satisfy that switch. Unfortunately I had already mounted and completely connected the pump, and I had situated it so that the pressure switch adjustment screw was facing a wall. After some adjustment, the unit works fine, and I found out that it wasn't running because of a thermal cut off. I just let it cool down and everything is good. The install was quick and easy. The pump on the board is much larger than just the pump that came in my rv, but I locked out that it fit perfectly on the floor inside the cabinet that the original pump was mounted in. Thanks to the additional connectors that were all included, I was able to shorten and properly connect the inlet and outlet without any modifications to the RV. I line the inside of the cabinet at this pump is mounted in with butyl rubber. Together with the rubber feet on the mounting platform, and the fact that it's just a quieter pump to begin with, the water pump has gone from something that will wake you up in the middle of the night to something that you strain to hear. Really nice upgrade

Oh my god. I should have bought this for my camper 5 years ago. I cheated out in 2020 and bought a super cheap $20 water pump. It shook so loud and violently I was embarrassed at campsites to even turn it on. Finally got around to buying this pump and accumulator combo. Holy crap it’s silent!!!! About as close to silent as a pump could get. It’s mounted in the back of a campervan under the bed and when running the sink I cannot hear it. It’s wall mounted as well and doesn’t vibrate anything. The zero vibration is definitely due to the mounting plate. It has rubber shock absorbing feet attaching the pump and accumulator to the plate. And the plate has a second set of rubber shock absorbers on water you mount it to. 10/10 would recommend this as an upgrade if you want a quieter pump. Been running this for about 4 months so far and I love it.
