Hello all,
I'm trying to figure out how to plumb the drain lines for a bathroom I'm re-modelling, access is from the utility room in the basement below.
Originally there was a tub-shower combo with a 1-1/2" drain going to the 3" main stack via a sanitary tee that was right snug to the floor joists above. The tub drain didn't have a vent installed but was approximately 4' from the stack so maybe didn't need one? Below that the toilet is connected to the main stack with another sanitary tee. See this link for a picture.
I've added a separate shower and replaced the tub, toilet has stayed in same location, and now I need to figure out how to plumb the drains. See this link - in this picture the main stack is in the bottom left corner.
The original tub san-tee is right below the bottom of the joists and the toilet san-tee butts right up to it. How would you tackle this? Bonus question - how would you arrange venting for the tub and shower, assuming access to the main vent is unavailable.
