Me again... was running some wire to the kitchen last night and when I
got down to the breaker box I felt a draft (last night was the first
really cold night we've had since moving into the house.) Apparently
this @#$%^$^& solar water heater has even more issues than I knew
about, there's a freakin' hole in the wall for the piping between the
tank and the panel, and I can stick my fingers in it and wiggle them
around! This is a basement wall, cinder block with brick facing on the
exterior. What to fill the hole with? I assume probably something
similar to the firestop that I'm used to using at work for sleeves that
are core drilled through concrete decks, but what exactly is the
product that I want to buy for this? Please don't tell me I need to
use concrete as it is probably way too cold for it to set up properly
right now.

thanks,

nate

There is some insulation stuff that comes in a caulking tube and foams
in place. My son used some once to seal up a house from a squirrel
invasion. Should do the trick here, I would think.

How big is the gap? When I had central AC installed once they busted out a
brick, ran the smallish pipe and hose and left a fair sized hole. I was
able to fill it with this caustic foam that came from an aerosol can and
expanded.

I've got big but slender hands, so it's not a HUGE gap... probably
something like two 3/4" copper pipes running through a rough 2" opening

Sounds like the stuff will work, hopefully someone here knows the name of
the stuff I'm talking about because I can't remember. These may be the same
thing though. I picked mine up at Home Depot so maybe you could ask there:
