I need to cut out an inspection hole in a kitchen dining area as neatly as possible. The drywall has wallpaper on it. This wall is common to a bathroom on the other side and I need access to the tub drain.
Instead of water backing up into the tub (which is last in line plumbing wise,before the main black water line leaves the foundation to the septic tank), it leaks out at the tub-drain joint and flows out onto the floor. I’m looking forward to fixing this one!
I’m seeking advice on how to cut out a large enough section of wallpaper covered drywall to minimize damage and when put back together, will look nice, since it will be in a very visible location.
Thanks in advance for your reply!
