Spray Foam Around Lines ?


The wall behind this is a poured "interior" wall near the center of home on the basement slab (extending up to the garage above).

The wall is uninsulated. There is roughly an 8" gap between the framing and concrete wall.

If this is foamed, from a maintenance standpoint, would it make repair of a leaky pipe that much harder? Should it be foamed? Heat/AC is not really an issue. This would be done to have a seal on it and help keep the stow under the vanity clean and bugs out. Including for the toilet supply not pictured.

Copper extenders added due to a thicker build-out of the wall after the plumbers did their thing. Please note their joiner locations where foam would be shot.

Just seams like committing to the foam might render any future pipe work, more of a challenge. But I don't know, I'm not the expert on exposing/replacing lines. Hence, I'm asking the experts.

I did the drywall/finishing and now ready to have the vanity installed ...

If it's an interior wall, any bugs would already be inside the envelope anyway, so not much point in sealing an area they can already get at from both sides.

Foam would gunk up the outside of the pipe and have to be cleaned off before sweating any new connections. Just stuff the gaps with fiberglass if you must, put escutcheon plates on and be done with it.

Re: Spray Foam Around Lines ?


Spray foam or other sealer should be done at the framing, coming out of the wall is not required. With that said it won't hurt to do it BUT it shouldn't really be done until after the shutoffs are installed, etc... (which is a pain)

As for harder for pipe repairs, well I would hope that there shouldn't be any, the only time it should become an issue is if they decide to remodel again & to move the lines in which case it becomes mute. Personally I would caulk it & slap the escutcheon on

Yes, repairs would be more difficult.
No, it should not be foamed.

It looks like the drain hook-up might be the fun part.

Pipe repairs? If you need to get that close to the wall you're cutting a hole anyway...big deal you gotta pick off some foam...but still I don't see the reason to do it in the first place.

If you only saw the surrounding framing.

...just checking the door latch.



- You see the plumbers did such an outrageous hack job on this bath they've got me questioning everything little thing they touched.
