DC HOUSE 12 Volt RV Fresh Water Diaphragm Pump 12V 3.5GPM 45PSI On Demand Self Priming Water Pressure Pump with Pressure Switch Quiet for Camper Marine Boat Travel Trailer Sprayer

Great pump. Every bit as good as the more expensive pumps I've used. I highly recommend it. And the company is easy to work with. I thought I had a problem at first but is was not the pump, it was my plumbing!

Wow. Talk about water pressure and durability! Installed as a retrofit on a 23 foot cabin boat and it’s got amazing pressure. The no run switch is great because it stops when the water is shut off. WRs fantastic. Great value and easy to install. Even lasted through a winter with water left in it!

This pump has worked flawlessly in my maple sap operation. I am very pleased with its performance in pumping as well as the low amp draw! I hope it lasts me a long time but if not, I will buy again due to how well it works in the application that I have it installed in..

I am using the pump to pressurize a RO water filter system. The pump is very quiet and is very easy to adjust the operating pressure. It has been operating flawlessly for a month. It appears that it will have a long service life.

Pump with a bypass works well. It is solidly built, compact, relatively quiet and puts out a good flow of water.

Can't contact seller. Amazon has no way to contact them and it says in the description we can contact them. My pump suddenly stopped working. It had worked beautifully for 6 months and suddenly stopped. If I pick it up it makes a gurgling noise but doesn't pump. I need help.

I used this as a replacement water pump in my RV. The old one started leaking and it was time to replace it. Installation was a breeze as it was a direct fit. The pump is sturdy and has vibration-dampening mounts on the feet to keep noise to a minimum. Setting the cut-off pressure and bypass pressure are also easy and is done using the provided allen key. I did have some trouble getting the optimal pressure vs bypass balance set properly and this is where the pump really surprised me. It's customer service. I had one of the best customer service experiences I've ever had with the pump manufacturer through Amazon's system. They really wanted to help me get things properly set up and that made buying this pump completely worth it.

I bought this pump to use with my rain barrel. The connections for the pump are half inch and a standard hose connection is 3/4 of an inch so I had to get some adapter connections.This pump came with a half inch water filter, but the threading seemed to be bad and it wouldn't connect to the pump. I replaced it with a 3/4 in filter, on the other side of the adapter. (If you could use the 1/2" filter that came with the pump you would just swap items 2 and 3 in my drawing. )So as not to unscrew the adapter connections when you attach the hoses, I finished the setup with quick connects. That seemed to solve the problem.I reduced the pressure of the pump to get maximum watering time with my wand. There is a small allen wrench in the kit that you use to adjust the pressure, after you remove the cover which is circled in the pictures of the pump.I filled my water barrel to 50 gallons to test it. I was able to get at least 15 minutes of watering time using the pump. It worked perfectly. Very quiet too.
