We are doing a major reno to our house, which includes an addition, moving the laundry upstairs, and adding a third bathroom as well. It became too many DFU for code for one 3" horizontal branch, and how some of the plumbing was done on the basement of this house was just a mess so we decided to redo it.
I started putting in some new plumbing fittings, following IPC 2015 (which is what Virginia follows). So far I have replumbed the main level half bath and started the new 4" stack to the upstairs.
Let me know if you see any code issues (of note the code does state that a horizontal branch cannot connect within 2' of a vertical stack but it explicitly states that this is for stacks with 4 or more branches) our stack will have 2 branch levels. So this should be fine.
Basement sub-slab connections and wye to pick up new stack and 3" to toilet/sink. Connected wye with 4" metal shielded no hub conforming to CSA b602.
Under first floor connections for main level bathroom, and stack to upstairs:
Main Level (4" stack not connected to upstairs yet, the vent connections tied together was existing)
Let me know what you think.
