Topic tags/keywords: question attic bathroom insulation plumbing parts

So I was crawling around in the attic of my ranch-style home installing styrofoam chutes to allow air to flow up from eave vents (thanks former owners for overlooking this task).

Anyway I am thinking about putting in a vent from the kitchen over the cooktop and so I crawled over to that spot and pulled back the insulation just to see whether I could figure out where the vent would have to come up.

Well I was on the wrong side of the truss and what I found instead was a 2’ x 4’ shaft that was wide open (only closure was the fiberglass insulation batt). It is formed between the shower/tub in the hallway bathroom and the shower in the master bath and allows access to the plumbing for each.

I assume that I need to have access to the plumbing, but should that shaft be closed off with something solid (albeit removable)? As it is, cold air can make it’s way down through or around the insulation and into the house.

-- If I can't make it, I probably don't need it.

My guess would be that the drywallers did not install the lid/firestop in this area because it was not in the living area or just because it was “too hard”to get into that tight space to hang it. Properly installed plumbing should not need an access unless code requires it (pump access, shut-offs,etc). I would close it off with some ridid foam and then seal it with Great Stuff or some other expanding foam and lay the batt back over it. If you ever feel the need to access this area in the future just cut out the foam.

I agree with Gary that it was too hard to get into the tight space to hang it.
