Author: packy (MA) since the minimum size allowed below grade is 2 inch, make the tub drain 2 inch rather than 1 1/2 inch.

Thanks for the reply.
Author: Bhavin (MI) Thanks for the reply. How do I connect to main sewage line and is there good step by step guide on how to layout my pipes? Where do I install the backwater valve, do I need one with sleeve? Venting through roof is not an option, I think I have studor ventfor my laundry, can I do same for sink/shower? Edited 1 times.

Author: packy (MA) yikes, i will go out of my way to help you but i'm afraid your extremely limited knowledge will make this impossible. you don't even know if your laundry is vented nor do you know if a backwater valve is necessary nor do you know how to cut into your main drain, sorry..
