Hello all,

We just purchased an older house and are planning to do some pretty extensive reno. Moving plumbing fixtures, running new PEX lines and moving a few walls (non-bearing).

In trying to create a direct hallway between the master bedroom and the 2nd bedroom (soon to be ensuite), I found the stack right in my path. So the question is, can I tweak it without interfering with proper drainage?

The clean-out in the basement and the secondary connected lines actually face different directions than shown in diagram, but I included them to show I was aware and there will be changes to the top connections obviously. The main floor lines actually become shorter runs to the fixtures attached.

But can I put the 45 jog in the vertical line? I am comfortable in running the new upper stack through the roof (cut a hole, new boot, new shingling, etc). There are a few flexible couplings on this line already, so some work must have taken place in the past.

be careful with a heavy stack can fall use proper couplings as well not the unshielded ones
