I have a 30 ft x 31 ft basement with 8 ft clear height to u/s of joists. The exterior walls are concrete and I plan to divide this space for extra living space. I want to add a full bathroom here and there is a 4 black plastic drain pipe (stack) coming down along the concrete wall from one of the upstairs bathrooms. Just about flash with the concrete floor there is a capped Y on this pipe, I guess to serve as a clean out.
Assuming that I can connect my new toilet to this Y, it is not convenient because it points to the opposite direction then I want to have my new toilet. Also I cant cut it off without breaking the concrete floor.
Since I have enough headroom, I could build a sub floor and have all new drain pipes under the sub floor or build a cavity wall and hide all pipes behind this wall. My questions:
1. How should I pipe the new bathtub drain, new sink and toilet to this 4 stack (pipe size & material)?
2. Any ideas as to how the connection to the 4 stack shall be made.
3. If I am not more than 6 feet away from the 4 stack, do I need to vent all new fixtures.
Another subject: All existing hot / cold water pipes are with a gray flexible plastic pipe. I worked before with copper & cast iron pipes but never worked with this new stuff. Any particular point to be aware off / careful
Thank you
