We're currently chipping our E19 out of the winter ice, and in the course of de-winterizing, and as usual when first putting the plumbing system under pressure each spring, I crawled painfully around on the floor and got my head and shoulders under the bed looking for any water leaks. And this time - for the first time - Bingo and Oh Crap-o! A slight drip from the bottom bypass valve. Having experienced several cases of "self-healing" hydrodynamic leaks over the years, I put the valve through 30 or 40 open/close cycles, and sure 'nuff the leak stopped - for now.
Don't know what's really going on inside the valve, but in looking at it, it seems like there is maybe a flat smooth surface and an o-ring and a couple of ports that do or don't line up depending on relative positions with some sliding/rotating motion, or something like that.
Anyhow, has anyone else run into this same thing, and if so once the leak decided to stop, did it stay stopped from then on?
In any case - a word of warning. While rooting around under there, I noticed that where the hot and cold Pex lines go forward and then turn and run across the trailer to the passenger side, the "plumber" at Escape was too lazy and/or ignorant and/or careless and/or behind schedule to bother to shorten the Pex lines by 1/4", leaving them longer than they should have been and they were pushed really hard into the nearby wiring bundle, forcing the Pex lines together and they had been rubbing and chaffing against each other. In fact, there was a layer of white plastic powder rubbed off from the elbow stuck to the cold line. I re-located the wiring bundle to allow the Pex lines some extra room, and will stick a piece of 1/8" rubber sheet between them.
