Plumbing Connections PM Tip

[ShinyPete]

On our 4 night trip over New Years, I was reminded of a plumbing PM tip that I wanted to share. I should have done this long ago, but it escaped me. It may save you from a leak that could go undetected for a while. Check the snugness of every twist-on plumbing fixture connection in your coach that you can access! Soon!

When I saw water along the floor edge of our center wardrobe I knew we had a problem. Turns out that the twist-on fitting on the back of our incoming water pressure regulator was not tight and it leaked inside the coach, following the maze of pipes under the wardrobe and showing itself the second evening. After some minor dis-assembly for access, I got the leak cured. And I also found 4 or 5 more twist-ons inside the coach that were not tight, really only snug.

The Pex fittings are pretty much forever (we hope), but there are a lot of the twist-on "ends" connected to things like the pressure regulator, the pump, all the faucets, the toilet, etc....... These twist-ons have a rubber gasket in them, so you don't have to horse them tight with pliers or anything, but several of ours were not tight enough at all. Now maybe these were never tight, or maybe they loosened a bit with vibration and use (1000 miles of towing and 75+ nights aboard in 14 months), but many of them were barely finger snug.

Check them. Soon. This leak could have easily escaped me, soaking the insulation between the skins, or the plywood floor, or whatever for days, weeks, months, and and if it remained hidden I wouldn't have known. $$ Oh and please don't forget to turn off your water at the supply when you leave your coach. I have seen water running out of rv doors before.............

Hope this helps.
