In this area it would'nt has we won't allow more than 2 45s at most to
a stack and 3 toilets least it is 6 inch Remember that no toilet
should be more than 5 feet from the stack as this is physics of water
not some code. Also if doing sinks after 10 ft they should be done in
2 inch as better flow is achieved. And after 12 feet a secondery vent
is required just makes for better flow and drainage.
