Hello,
First post here. I am currently finishing my basement and have come to the stage of laying out the bathroom/laundry room. Please see the attached drawing. My home has a lateral sewer that is either a 3" or 4" (not sure, was built in 1953). This lateral tees off to a 3" stack that serves a full bathroom above. My intention is to open up the 3" line and to install a 3" wye connection that will serve a toilet, then wye off to a 2" line that will serve a bathtube, then wye off to a 2" line that serves a shower. I will vent the shower and tub via a 2" line (can I use 1.5"?) in the vertical, the toilet in a 2" to the vertical (which will also serve as the drain for a bathroom sink), and the laundry in a 2" line. These will all tie together before going to the roof. For the laundry, I was going to remove a floor drain that connects to the horizontal lateral and install a 2" line to serve the washer and a utility sink.
Any comments on whether my plan is appropriate or suggestions for layout would be greatly appreciated. The yellow highlight is new work and the orange is existing.
Thanks.
