Can I add a 1.5" drain from a new soaking tub to 3" toilet waste pipe by extending the clean out with 3" transition + 3" adapter with 1.5" inlet +new clean out transition? I am concerned that the vented waste pipe could siphon out the tub trap? Venting the new line is possible but difficult. It would require a 1.5" saddle adapter to the toilet vent pipe.
how far is the toilet from the main stack?
