A did that sound like a viable solution??


Finished sealing up the rim joists in our new house last night and noticed a large amount of lint along the dryer vent. Pulled it all out and checked the joints and all are taped tightly so I was perplexed. Look a little closer.... apparently after the drain and water pipes were in the dryer vent didn't fit by 1/2", so the best solution was to cut out the vent around the copper water line. Metal rubbing on metal, and hot, moist, full-of-lint air blowing directly on it, let alone into the basement in general.
This is a prime example of why I personally wouldn't buy an already finished basement

Nice find. I guess "new" doesn't always mean "problem free".

Question for you: Did you spray foam in the edges and then press the rigid foam into place or did you press the rigid foam into place and then spray along the edges? Perhaps both? I need to do my crawlspace.

I cut the foam 1" short each dimension so I had 1/2" all the way around it to spray foam. I dry fit all my rigid pieces in place and then went back around and filled all the gaps with spray foam.

If copper and aluminum are in direct contact it is more than mechanical rubbing--there will be a galvanic current between the two metals.

Edit--after posting looked at the picture again and now I think the dryer vent is galvanized steel. Much less a problem for galvanic currents but there should not be any contact with copper water lines to aviod problems.

Wouldn't you love to "talk" to the person who did that. They probably had the thought, "Screw it just get it to fit somehow, it's not my house or I'm selling it anyway"

I totally agree with the statement I quoted from you.

In the joist bay to the left; there appears to be a below the subfloor trap there. What is that for?
