Will this pass inspection?

I am designing the plumbing for a guest bath in a new post frame home. I have attached a 3D rendering of the plumbing and want to know if there is any thing I need to do different. Any advice would be greatly appreciated.

 

If the arm on the lav. waste is less than 36" it can look straight out without the re-vent.

 

Thanks for the reply John,
One concern I have is the vent for the tub has a 6" long horizontal run over to the vent in the wall. Does this hve to connect to the tub branch with a wye, like shown, or can a saniary tee be used turned to a 45 degree angle with a 1/8 bend to go up into the wall? Or, could I move the tub branch over, directly under the wall, and come straight up with a sanitary tee for the vent? I have attached a plan view of the bathroom.

 

I would just run the pipe so it goes UNDER the wall with a combo facing upwards and then connect it to the main.

 

Where did you get the 3D program?

 

Turbocad Deluxe 2019. I love playing with it. I am currently modeling the entire post frame home we're going to build.

 

If anyone can make heads or tails of this, is there anything I left out, or should do different. This is a rendering of the entire drain, waste, vent for the home I will be building.

 

Oklahoma uses IPC. The washer standpipe output should be 2 inch but go up to 3 inches when it joins another drain. https://terrylove.com/forums/index.php?threads/washing-machine-pipe-sizes.83667/#post-602970

 

So just upsizing the 2" from the 3x3x3 wye leaving the house to where the washer drain connects should solve the problem?

 

I think so. I am not a plumber. I would interchange the from and the to, but that is just semantics.

 

Here is a different view of the 3d rendering that is much easier to understand with a few changes. I think I have it the way it needs to be, but I would really like feed back as we will be preparing for slab in the very near future.

 

one-way cleanouts usually point downstream.

The downs stream toilet may need its own vent the way it is. If that toilet joined after the lavatory then probably not.

 

How about this? The tub ties in before toilet. The trap arm to the tub is 2' 6".

 

Here's a view from the other side

 

I think that would be good. Standard disclaimer applies.
