Will this pass inspection?

[Mark Mathe]

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?

 

[Mark Mathe]

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.

 

[Mark Mathe]

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.
