I am in the very early stages of planning for a renovation of my full bath on the second floor. To allow plenty of time to do the work
, I plan on setting up a temporary shower in the basement.
My question has two parts. First, I am curious to know if there are any questionable plumbing practices shown in the attached picture. Based on some screwy electrical things I've found, I wouldn't be surprised. So please take a close look and comment on what you see.
Please note that the vent in the top picture turns 90 degrees at the basement ceiling, crosses the basement, and connects to the stack in the middle and bottom pictures where I have indicated. Seems interesting, but I would like your thoughts.
Also, whoever added the half bath off the kitchen seems to have brought the vent shown down to the basement to connect to the existing vent. Is this okay?
The second question is this: what would be the best way to drain/vent a shower into the existing plumbing? I would like to use a Saniflo Sanishower or equivalent product to avoid any concrete smashing.
Please let me know if you have any questions or need any clarification.
FYI, I live in Erie, PA where we follow the 2003 International Plumbing Code, according to Erie's Uniform Construction Code.
