Can Not Find Leak Help!

[Rennegarbe1]

Still looking for leak in my 1976 Trade Wind. The leak is in the bathroom closet. I have rechaulked the vent pipe and the hinges on my Zip Dee awning. Could it be the vertical rivets? I don't want to let myself think that. The PO chaulked all the rivets on the front of the trailer and it looks terrible. I wanted to remove all of that when I polish. Has anyone had experience with vertical rivets leaking? Please help!!!

Lisa,
you mention recaulking it but, you also know that the vent pipe has a gasket that needs to be replaced abt once every 5 yrs??
it's not expensive to replace..check this place out.
Should be around ten dollars or so..

How does the screen fit in the vent?

Dan,

The screen is laid over the top of the rubber gasket and then you screw the collar down.

Lisa,

Leaks at the rear closet can come from anywhere on the roof, I would suspect a riveted joint last, usually what leaks is either your vent pipes, antennae mounting or a/c unit. Usually when you unhitch your A/S the rear sets lower and the water will get between the skins and run towards the back.

Persistance will be required on tracing it down.

Good Luck,

Chas

so does the screen actually go over the vent pipe, to keep critters out?

how are you supposed to seal up around the a/c? I was checking that out last fall, and it seems that there is what appears to be a piece of foam-rubber wedged between the a/c housing and the hole in the roof; not a real "joint", so to speak, where some horizontal piece of metal (flange?) overlaps the roof, into which you can squeeze a bead of sealant....know what I mean? didn't look like there was any way to caulk it.

Chuck,

Yes, the screen just lays on top of the pipe and is sucked down tight when you screw the collar down.

Regarding your a/c seal, it looks like you have a Coleman Mach on your A/S, am I correct? Not sure how they installed it, hope it is properly braced between the skins because that is the key to them sealing well. I am familiar with both installs and the Armstrongs screw down or rivet to the exterior skin and are sealed with Vulkem, not a compressed foam seal like the Coleman units. Caulk will not help a bit on sealing a Coleman unit.

[Chuck]

yep, its a Coleman. So what do I do? just hope it ain't leaking?!

[Chas]

You got it!

If it does leak try tightening it up a little first. Pull the plastic cover and there are 4 bolts that hold the outer unit to the roof. Give them a couple of turns to compress the gasket. It is about 1 1/4" thick so can usually be compressed to reseal. If that doesn't help replacements are available.

great tip...I'll have to look for those bolts. didn't notice them when I was poking around up there before. and actually, I don't know that there's a leak there.....I suppose the only way to know is to pull off the ceiling from the inside and look. something was leaking up there last fall...enough to short-out the middle overhead light, (not tooooo far forward of the a/c) and drip a little water on the floor. First suspect was the vent over said light fixture, of course. Haven't seen any more water come in since I went up on the roof and re-vulkemed everything I could. (except the a/c). just want to cover all the bases...tweak anything that "might" leak.
