Looking to get my SCA 80g build going. I want to plumb it to the garage where I plan to keep my sump, skimmer, and other equipment. I cut the drywall from the garage and saw that there is OSB sheathing on interior wall. Can I cut this or would I be breaking some code?
If this is allowed, should I just run the PVC through opening or should I use some support for the PVC?
