Uknown Leak

I have completely sealed my AS except for this one spot. It keeps leaking heavily above the kitchen stove and window (see picture). I have sealed above the window, the stove vent, and any seams and rivets I could find in the general area near or above. I also sealed where the air conditioner meets the skin. I have not even been able to make a dent in this leak. Has anyone else experienced this leak? I have tried and failed to track this down so now I reach out to you guys.
Could this be coming from the air conditioner? Have I missed something when I sealed the stove vent?
Thanks!!

You may find as I sometimes have that it is necessary to remove the air conditioner to find out what's going on.

Could be from a sewer vent pipe cover.

Those gaskets only last 2 to 3 years.

This may be a long shot, but something to address if you haven't already. Your plumbing vent stacks are probably not too far from this area. If you haven't rebuilt them and put in fresh rubber gaskets, it could be that they are leaking like mad. IF they are the originals, then they are definitely leaking like mad, and you just aren't noticing the water because is puddling at the base of the inside of your wall.

I figured that might be a source. I did purchase new gaskets and will replace them once it stops raining. Thanks for the tips. I will re-post once I do that and let you know if it works!

Remember that the AS has horizontal stringers that will allow water to travel too...

Here is the culprit you are looking for. There are three on the roof, the one to start with in your case is over the galley.

They look nice, once cleaned and slathered with too much Vulkem.


But you'll be surprised how much guck they can hold. Here is the gasket you will replace:



There is also a small piece of screen in the 'kits' that are sold to do this. Make sure the screen protrudes above the top of the hole, otherwise it can allow leaves and squirrel recycling to plug get into the pipe

I think you may have covered the weep vents in the bottom of the metal cap there... Gotta have somewhere for the water that gets in between the stack and the cover to go.

Good thought, Aaron. I did that work waaay back when Henri was new to me, so while I don't remember any weeping holes, it IS logical that they be there.

I plan on re-doing them this summer, so I made myself a note to remember to leave the weeping holes open, and pull the screen up to deflect leaves.

Thanks!

FWIW I use EPDM (black rubber roofing) it lasts a fair bit longer than the regular black rubber gasket materials, 5 years and counting. The EPDM has a variety of UV blockers made into it to provide some longevity as a roof material. I will be inspecting mine again soon and can provide the 6 year update.

Where do you buy EPDM in small quantities?

VTS has a fully covered vent stack that does not have this problem. I just put some Trempro-635 around that vent pipe and put the Tee-Pee back on and it is still leak free after 2 yrs. I will probably modify the Tee-Pee by putting some sort of top hat on it and then the inner gasket does not matter.

Also it could still be your stove vent. Mine had a crappy flap door that would sometimes leak and sometimes not leak. The vents with the scoop on the outside don't have this problem. I cpvered the vent with a solid plate till I get a chance to make a scoop for mine.

Ask any commercial roofer, they probably will have plenty of small scraps they would be glad to give you. You could also ask a commercial roofing supply for some samples. You only need a 6"x6" piece for each one.

It is "not" necessary to seal the metal vent cover.

The gasket takes care of that.
