rrlowther Report post Posted September 11, 2011 Okay, so we're still learning. I know I know. It's a never ending process. But I wanted to ask. We were sold a pressure reducer to used when connected to shore water. My question is, how important is this and do I need to use it any time I'm connected to shore water? Appreciate your thoughts.

wolfe10 Report post Posted September 11, 2011 A pressure reducer is not important UNLESS (read that as a very LARGE UNLESS) the shore water is at high pressure. If it is, you can easily rupture plumbing in your RV, as it was not designed for the pressure present in a lot of city water systems. So, unless you check the water pressure before hooking up, always use a pressure reducer. There are inexpensive ones that work fine, but do restrict volume and more expensive ones that do a good job of reducing pressure without reducing water flow.

ClayL Report post Posted September 12, 2011 I use the setup recommended by Brett. As to how important it is - in my 9 years of full timing I have seen pressures as high as 150 psi in some campgrounds. That can be enough to cause some serious problems. I don't see pressure higher than 45 psi often, but it only takes once... Share this post Link to post Share on other sites
