How close to a toilet flange (3″ pipe) can I tie in my shower and sink (2″ pipes). All of it is going into the sewage ejector (lift pump). Should I tie in my shower drain to a 3″ pipe coming off of the main 3″ discharge pipe dedicated to the sink or should I just tap into the 3″ main discharge at two different places?
You dont want to connect into the discharge pipe, you have to go into the inlet pipe, if you go into discharge pipe it will blow water out of the fix. Can you send me a drawing so i can see how it is connected. email@example.com
