Hey Gang, Here's my bathroom group for an ADU. Is there any benefit going all the way to 7'8" inside the wall cavity for all the vents? Can I move that cross down and just go up with a single 2" pipe to roof? Thanks much,

Hey Gang, I'm planning a DWV system for a 252 square foot tiny house. I've mocked it up in SketchUp. I'm planning on 2x6 plumbing wall so I can access the three inch cleanout under LAV sink. The cross will vent to roof. Does this system seem OK? Thanks much.

Hey Gang, I’m converting an old 1900’s basement. Does this look OK? Thanks much,

Hey Gang, First post here. Thanks for having me. I don’t have enough room to adapt to PVC so I went with No-Hub Cast Wye. The issue is my 4x4x3 Charlotte Cast Wye is too small for the 1900’s extra heavy cast iron. (1/4" smaller) See the images for a circumference comparison with a guide...
