Below are some images containing my plans for the drains in my project.http://countryplans.com/smf/index.php?topic=12814.0 (http://countryplans.com/smf/index.php?topic=12814.0) While I have done a great deal of plumbing work, I have never started from scratch like this before, so I really need some help. For my project I plan to keep the gray water and black water separate so I can install a gray water system at a later date. I used 2012 IPC as a basis, so I think I am in compliance. The only think not included on this diagram is the vent for the graywater sump.
I plan to use 3" pipe for all of the blackwater applications, and primarily 2.5" pipe for the graywater applications.
Thanks in advance for any advice.
