I am looking to add a 1/2 bath to my basement and would appreciate feedback on my plan before I start to buy/build. Attached is a picture of the existing 4" cast stack. We plan to replace all the existing drain except the 45 buried in the concrete. the 2x4s laying on the floor are there to represent the approximate location of where the walls of the new bathroom will stand.
Here is the parts list I am planning to purchase. Each number here corresponds to the numbers in my attached drawings
1) 2" 90 Elbow (for vent)
2) 2" x 2" x 1-1/2" Wye & 1/8 bend (sink)
3) 2" x 2" x 1-1/2" Wye & 1/8 bend (sink)
4) 4" x 4" x 2" Sanitary Street Tee
5) 4" x 4" x 3" Sanitary Street Tee
6) 3" x 3" x 1-1/2" Wye & 1/8 bend (stand pipe)
7) 3" Long Sweep 1/4 Bend
8) 3" HDPE Straight Connector (Part:366.887.16.1)
9) Concealed Toilet Carrier & Tank (Part:111.335.00.5)
I'm fairly certain that I've used the right fittings in the right places (Wyes vs Sanitary tees) but I would appreciate any corrections.
I drew a vent pipe on the sink side of the stack because I think it's required. Does that seem correct?
Do I also need to put a vent on the toilet side of the stack as well or is it not needed because of how close it is to the stack?
I have tried to do my research before making this post but I am not a professional. Any/all feedback will be appreciated. Thank you.
