Sewer vent

[Vicki A.]

Finally found a ladder that could get my little 5' body to reach some of the roof, oh the things I found!
First I pulled off the old sewer vent ( looked like a coffee can with slots in it ), anyway... I found the vent pipe does not rise above the roof, is this a problem or is it okay? I was also wondering new stlye plastic base and cover will work on a '79 Argosy.
Thanks for your help!

Got any pictures of that?

Pictures of the old vent cover or of the vent pipe below the roof line?

Your Minuet should have had the same vent cover as any Airstream except yours would have been painted. In order for the gasket to work properly the vent pipe would need to extend above the roofline at least an inch or so. See below for parts and a photo.

This is my vent before I replaced the screen and gasket.

You are very fortunate it looks so nice!

On my project trailer the bath black-plastic pipe had eased downward when the clamp bands below loosened... Down, down and down it went until jagging sideways under the outer shell aluminum & effectively blocked most of the pipe & coerced the stack gas back into the trailer... I ended up condemning the whole interior - that was maybe part of the larger problem!

Had a chance to go back and look at my vent pipe. Someone cut it not at the roof line but below. I went into the closet to see if I could simply pull it down or push it up (silly me), it didn't budge. As the joints are all solidly in place, is it okay to cut the last section and just add on? This is going to be a necessary thing to to do, right?
Oh, by the way, under the "coffee can" cover sat the remnants of an AS stlye cover, but made of fiberglass.

i seem to recall that the vent can slip down into the tank. maybe someone more experienced than myself can chime in.

Vicki,

If it is solidly mounted in the tank and all other joints are intact I don't see why you couldn't sleeve and cement an extension below the roofline, extend thru and replace the cover.

If you note in your picture above the screen was placed over the pipe then the rubber gasket was pulled down over it. This was also done on my '92 excella.
The problem with this is simple. Screen is designed to allow small things to pass through it. Water molecules are very small. You should put the new rubber gasket over the pipe first then attache the screen over top of that. This can be done simply by placing a zip tie around the pipe. The screen is not as necessary as the gasket. It is only there to keep bugs and small rodents from finding their way down the pipe. I actually upgraded my screen from the nylon version I received in the kit from Inland RV to an aluminum version I purchased at the local hardware store. This was easily bent to form a nice dome that protrudes out the top of the vent cover. This will help keep leaves and other debris from filling the space between the pipe and the housing that may clog the small train holes at the bottom of the cover.

Keeping water from traveling down the vent pipe to my newly replaced floor is my primary goal.
Best of luck.

Here is another option for vent screening. I bought a $1.98 tea ball, took it apart resulting in two stainless dome shaped screens that fit nicely on the vent stacks. Just used some caulking to fasten in place.

This is a picture of the old vent gasket showing how the hole should be cut.

No slit's to fit it over the pipe, the hole should be slightly smaller and fit tightly around the vent pipe. I re-inforced the the seal with sika.
