Received our new JX450 just before Christmas and after bringing it back to the park where we full time, noticed a small drip under the water panel. Checked it out and found more than half of the plastic fittings that screw on to the 3 way water heater valve and 4 way water valve were fairly loose. The valves are all brass but the hose fittings are plastic. Tightened every fitting back there by hand as tight as I can manage. Pulled some of the insulation up and put a fan in there to dry things out. Two were still found leaking the next day. After more investigation it looks like the plastic fittings bottom out on the brass valve before the seals are adequately compressed. I have a pair of 6” (small) channel locks and tightened the fittings a little more over the next few days and stopped the leaks but now I worry that the plastic fittings may decide to crack at some future time. Checking here to see if others have seen the same issue. I’m thinking it would be nice to find a PEX hose fitting (hopefully brass) that is more compatible with the brass valves. If I find such a fitting, I would replace them all.
