Hello everybody. I'm very glad to have found this forum.
I think I've read nearly every page and have gained a lot of great info.
We have owned a 26 foot 1975 twin bed Argosy for about a year now. On our last camping trip, I noticed a sizable drip of water at the rear center of the vehicle. I spent the last 3 months depressed about it (knowing how water can totally ruin the trailer and really not knowing how to fix it), then started digging into the problem and discovered that fixing it wasn't all that difficult:
I found one leak in this stuff and used a rubber hose and clamps to fix it. In the process i either created or discovered another leak, more hose and clamps. The third leak I "mended" with JB weld. After a nights drying time, i decided not to even test my handiwork. I pulled all this stuff out. Good thing i didnt' test it because it turns out the JB weld mocked me by twirling around the line i cleaned up and put it on................how rude! I'm not a very good JP welder. I know people who swear by the stuff.
Replaced the copper with pex. I put a valve on each branch line because i knew i had another leak somewhere and i wanted to isolate it.
I found out i had a leak in the cold water pipe going to the kitchen sink (I'm so thankful the leak wasn't in the lines going to the shower! I don't know how to get in to repair it there).
The next step was more investigating. What you can barely see is a hose and pipe clamp repair made by a PO and probably the source of another leak.
I didn't know which way the pipe ran and naively investigated the possibility of taping the pex to the copper and pulling it through.........nope.
I originally thought that the pipe took a dive under the tub, and after looking through the form, wasn't able to find a picture of how the pipe ran (there's probably a picture on the forum somewhere but i wasn't able to find it).
I don't know what the flattened out heater hose is all about. I don't have a picture that shows it, but the copper has been replaced by pex. It feels so great to not have a leak any more.
Axles are next, they should be here the middle of next week.
