I have a 4" thick concrete block wall between my utility room and
Due to new plumbing (washing machine, laundry sink) and an adjacent
half bath, I have two 2" PVC vent lines that runs up the concrete
I do not want to chip out a vertical section of this concrete wall to
recessed the vents. Furthermore, there are some 3/4" copper supply
lines that run horizontally, going behind (I did chip out the walls
there) where they meet the 2" vents.
So I decided I will furr out the wall by using 2x3 studs spaced 16"
apart - thinking 2x3 is about 2-1/2" wide, and the 2" vents are 2"
diameter "nominally" which is actually bigger than 2".
But how do I attach the 2x3 studs "depth wise" to the concrete wall?
I cannot use 5" Tapcons and it might split the wood. Do I need to use
some special Simpson brackets or angles?
