Quieter Water Pump

In the two previous motor homes the base model ShurFlo pumps were intolerable. In our 2002 RoadTrek, I installed a FloJet variable speed pump. Very quiet and provided an even flow of water from a trickle to full flow. We had a faucet mounted Pur water filter and when getting water from it you could hardly tell the pump was running. In our 2009 Navion, I installed a ShurFlo variable speed pump hoping for similar results. Not as quiet as the FloJet, and had a tendency to cycle a bit at low flow. However, the vast improvement was good enough to keep that pump and not experiment with anything else. Our new RV should arrive in a week or two and I suspect I will be getting out the tools again. Both previous pumps have been superseded by newer models. A friend installed a ShurFlo pump with a bypass feature in his Fifthwheel and that seems to make a big improvement with reduced cycling and a more even flow. If you use the pump often, my advice is to not go cheap on the pump. Get the top of the line and you will have no regrets when you turn the water on for the first time. I have experimented with pump mounting and water line connections. There you will get the best noise isolation for your effort. I would not recommend an enclosure for heat dissipation reasons.

A story I tell often is about the time we were camping in Yellowstone with our RoadTrek. One morning a tenter in the site next to ours asked if we would not use our generator at night. I told him that our RV did not even have a generator. It was the water hammer in the PEX plumbing in the walls of the RoadTrek when the toilet was flushed or sink being used. First thing I did when we got home was to go to Camping World and get the FloJet variable speed pump.
