1. Can a toilet sit at the top of a soil stack (no bends between the flange and the stack)? It seems like this would be OK, but I never see it done this way.
2. When tying a drain from a tub or sink into the soil stack, is it OK to use a wye instead of a san-T? In another post (https://terrylove.com/forums/showth...om-toilet-into-stack&highlight=soil+stack+top) it was stated that you could only do it with a toilet, but I think that it should be OK if the tub & lav have their own vents.
3. When combining two 1.5 in vents to go through the roof, what pipe size should be used after combining.
Thanks,
Lance
