Hi All, I'm new to this forum. Hoping to get help with designing plumbing scheme. I'm handy DIYer, but don't know correct fittings to use.

Please let me know if I can post scheme of bath here, or if it's not allowed I'll delete topic then.

Thanks!
 
ok, let me post details, here is plan of addition (left bottom corner )

Existing sewer line is iron pipe, as I understand I'll use Long-Radius Combination Sanitary Tee (connection #1 in 1st picture):

Connection #2 is where I have questions, here is diagram I made:

c1 = 2 in. PVC DWV Hub x Hub x Cleanout P-Trap Fitting
c2 = 3 in. x 3 in. x 2 in. x 2 in. PVC DWV H x H x H x H Double Sanitary Tee
c3 = 2 in. x 1-1/2 in. x 2 in. PVC Hub x Hub x Hub Sanitary Reducing Tee

Is that completely wrong by the code?
Ventilation will go from C3 up to the roof, an I have only 1 vent for all of this?

Please help.
Thank you all.
