Water in large window

[Shane826]

It could be part of the issue as there is a lot more weight hanging over the open end of the shell which could compromise the roof crown. But you can’t just move it… The A/C mounts over a 14”x14” hole on the riser. The only way you could posssibly (and I stress POSSIBLY) change it is to remove the A/C, skirt, and riser; and then rotate the riser 180° so the 14”x14” hole is further towards the front, then reassemble. But that might not even work since you’d also have to rotate the skirt 180° and then it would probably hang off the back edge.

I dunno. I’ve never seen that before.

If I understand the construction of the TM shell I believe any water that enters at the compressed gasket would only manifest as dripping from the AC frame and not at window. I barely have a drip there so sounds like I don’t need to mess with repositioning the AC .If that’s the case I think the leak at the window has to be entering between the riser and roof, and the hose test should confirm that. If I have that right will confirm with test then redo the caulking at riser and then only fidget with evenly tightening 4 bolts as needed to address the drip from the ac frame.

Yep you’re on the right track.

Thanks, is the compression gasket supposed to cover the entire perimeter between riser and AC? I see a gap with no gasket .Here are some pics of the AC.

No it just surrounds the 14”x14” hole. In fact, see all those foam strips hanging off the back? Those are supposed to act as supports to keep the A/C level on the roof (or in TM’s case on top of the riser).

Updates.
1. Ac internal leak stopped so good there with compression gasket
2. Completed dicor sealing all around AC riser (see pics )before hose test
3. Hose test fails . Had a real hard time identifying source as it takes quite a bit of water to generate the slow and steady drip at window. Thought it was fan above stove but seems to drip steadily at several places including center seam.

Any ideas where it could be coming from? Next step? I really cleaned well (scrape, mineral spirits, wipe clean , alcohol) before generously applying Self leveling dicor. Hate to remove all risers and center seam after all that but not sure what else to do?

What is that?!?
