Yet another basement rough-in

[JackJ]

Picture shows my proposed fittings and setup. I think I've researched everything and read hundreds of pages about this but I'm wondering if anyone can spot any issues? Your opinion is greatly appreciated. I'm getting ready to submit this plan to the building inspector and wanted a final once over by you.

Couple things worth noting about this:

• The yellow crowbar is where everything flows to I'll join that up with a Fernco fitting to CI main.
• Spaces between each piece of the system will have pipe I only did this for visual sake so please just imagine they are connected with PVC.
  
• WC, Vanity, Shower are the three fixtures.
• WC is a Sioux Chief 45 and then a street 45.
  
• Distances don't exceed the limits of the IPC for wet venting.
  
• Starting at the crowbar its 3" then goes to 2" for most everything
• Except the vanity is a sani T which is a 2x2x1.5. [disregard that it is upside down I only did that so it would stay on the tube holding it up for visual sake it will go the right way]
  
• 45's are a combination of street (F-M) and regular (F-F)
•

I would work to reduce the number of bends and allow for cleanouts.

Will the top-side of the san-t for the lav be the only vent for this bath group?

Wouldnt it be better to move that 3x2 Wye a few inches down and flip it on the other side and drain the sink into it as shown by the red line? And do similar with the shower drain instead of like cacher said all those bends??

Move the 3" wye further away from the closet bend and butt your 2" wye onto the 2" port of the main line wye. The shower drain could be straight, and the lav drain would only need a single quarter bend.

suddenly, everyone wants to be a journeyman plumber. Put a 3x2 combo in the main line facing DIRECTLY towards the shower trap. Put a 2x2 combo into it, then run the side branch of the combo to a point where a 45 will line up with the lav.
