Soon I will be remodeling my 2 bathrooms. They are back to back style bathrooms, and currently have 1- 3" vent and 1- 1.5" vent. In the front bathroom I will have one whirlpool bathtub, one sink, and one toilet. In the back I will have a shower, two sinks, and one toilet. Everything will be the same with the addition of one new sink. I plan to relocate some of the fixtures. My question is: Can I tie all of these vents i.e. shower, tub, sinks into the main 3" stack or should I keep the 1-1.5" stack and tie the sinks/shower into that line? Thanks- Andrew
