Quick IRC code question: PVC vent piping for bathroom exhausts.
Does the IRC allow the use of pvc for vent piping of bathroom exhaust fans?
I know the IRC doesn’t allow the use of pvc for dryer vents.
I just need to know if I can use it for a bathroom fan. Both local suppliers were out of 4-inch galvanized vent pipe today when I went to buy some. And, I would really like to finish this project, this weekend.
