: If you have the wall open, you can always sister the notched stud with another notched stud, if it makes you feel more comfortable.

: : : : I am getting ready to rough in valves for my new vanity area. The wall is an outside wall (therefore load-bearing). If I am going to center my set-up on the available wall, I would have to notch one of the load-bearing studs enough for part of the valve to fit in and to allow access for line hook-up. What is the proper way to do this? Is there a proper method to notch a load-bearing stud that makes it both safe and proper?

: : : : Thanks for your assistance.

: : : A maximum 50 %notch in one stud will NOT create any problem. Only notch in halfway (max).. The wall being attached to this stud will help this stud avoid any deflection. Hube

: : I guess I should have mentioned, originally, that this is an existing structure. The house is about 30 years old, so all attachments (i.e., plywood, bricks, etc) have been in place for a long time. I take it this makes the 50% issue even less of an issue?
