I am new to this forum and need some help. I live in CT and recently had a new sewer line installed. Due to pitch issues I could not connect to the existing CI pipe to the septic tanks. So now I need to re-route through my finished basement and downstairs kitchen. My house is 50 yrs old and the plumbing is completely copper. The bathrooms upstairs are back-to-back and have back-to-back toilets. There is very limited space and height is an issue. The toilets are connected horizontally with a double TY (see pictures). I know this is no longer allowed and since I have to re-route, I am attempting to design this code and need some comment on what I believe is the solution (see sketch). My thoughts are to connect the toilets with a double wye & 1/8 bend combination and have this feed into another double wye & 1/8 bend combination to pick-up the tub/shower/and sinks. I'm not sure how to maintain the pitch on both sides given the short distance. The toilet side should be fairly easy in that it is all new, but the other side will need to drop about a half inch over maybe 5-6" to enter the branch of the second double wye. Can anyone comment on my proposed layout as per adherence to code and connecting the fittings with pitch? The line to the sewer connection will be approximately over the light in the picture.
