Final plumbing question (I hope!). My tub and shower are within about 2 feet of where my sewer main and 4" stack are. Am I correct in assuming I can tie both directly into the main here without needing separate vent stacks for them?
1x tub (3 feet from main stack)
1x shower (2 feet from main stack)
3x lavatory sinks (10 - 14 feet from main stack)
1x kitchen sink (12 feet from main stack)
1x toilet (12 feet from main stack)
As referenced in the other threads, the toilet has it's own 2 inch vent pipe before tying into the sewer main. The kitchen sink will have it's own vent pipe as well. The 3 sinks under discussion in this thread will have their own vent pipe as well.
So that leaves the tub and shower, either needing their own vent(s) or hopefully using the main stack directly.
