Ok, two quick questions. 1. Does an interior wall require anchor bolts on the sill plates? I noticed none were present on the walls below the stairwell. I know they’re required on outside walls, but are they required on interior walls?
What are your thoughts on the piece of pressure treated wood on the ceiling in this photo? I noticed an orange spray foam, but don’t know if it’s fire-resistant. However, the piece of wood has me flummoxed. It covers a couple of pex water lines that feed the master bathroom above. I didn’t see any signs of leaking. I couldn’t figure it out. I’m thinking maybe it’s a construction thing I’ve not encountered yet.
Ok, Thanks guys. The firestop is already compromised. Near the board in the ceiling is a piece of 2-inch PVC pipe that extends down about a foot from the ceiling and is the drain for the TPR valve in the attic. Somehow I don’t think stopping a foot from the ceiling is the same as stopping a foot from the floor.
