My 2020 Thor Coleman 23CM class C leaks water on the bath room floor every time I do not use a water regular. At one location water pressure cuts off at 60 psi. One would think that's not to high but it leaks. It takes about 12 to 24 hours then leaks around plumbing fittings again. Most all of them in bathroom and probably the whole coach not good. Then I install a water regulator Camco 40 to 50 PSI and no water leaks but very low water flow in shower. Not enough flow to use. My question is the little metal rings on plumbing tubing that has two little ears on each side do these need to be replaced with better fittings ? Why does shower have low water flow when on regular and pump works fine ? I changed water filter and still does the same thing. I thought the filter was stopped up but its full flow. This one has been a puzzle.
