Im moving this water heater to the other side of the attic and I am wondering whether I can take the two 1 inch pipes through these three 2 by 8s that connect all these joists. I'm not sure what the term for it is. I want to call it a header but there is no support underneath it. It is one big room underneath so this is here to span the joists all the way across. Im guessing it's not a problem but I want to make sure since this is a very integral part of the floor. I know the rules for drilling through joists and obviously in that case I would be more than fine but not sure if this is different.
