Default Inspector failed my DIY job... NEED HELP/ ADVICE

Hey Guys...I came across this forum when I was searching for Back to back toilet drain installs. My inspector told me that my drains are not vented properly and I used the wrong cross wye to connect my toilets. I included some pics...Please if anyone can let me know what I would have to do to bring it to code. House in Long Island and I'm expecting a baby any day now and need to get this solved so I can continue with the project. Thanks!

Before







After





Is there anything wrong with the after before I have him come back to inspect it?? Any help would be greatly apprciated

Where your toilet ties in the first thing it has to connect to before it connects to any other drain or toilet is a vent. Here you have two toilets tied together and no vent at all. On the toilet arm before they connect to your main they need to have a vent connected. Also just curious but I don't see any primer on your joints, sure hope you did prime them.

Not only is the venting incorrect but you have destroyed the floor joist. No primer as Steve pointed out is also a no no. If I'm not mistaken this will be second inspection you have failed.

You guys are right about the primer... I just connected everything dry for now before I glue anything up to make sure that it is correct. The floor joists are going to be sistered and reinforced. My question lies in where would I put a vent if not downstream of the closet elbow? As you can see I have limited room. And because the main drain lands above a finished room downstairs in the center of the room I wouldn't be able to come down with any of the pipes. If I roll that 3x3x2 wye to make the vertical it will interfere with the floor

I'm cringing at that floor joist. The structural integrity of that joist has been compromised and it may break. There are building code restrictions on how far you are allowed to cut in to a joist without it compromising the structure.

You should never EVER cut into the top of a floor joist like that-- especially not a section that wide. Holes must be at least 2 inches from the top and bottom of the joist and must be no larger than 1/3 the size of the joist.

A quick little bit on joists: http://www.familyhandyman.com/floor/how-joists-work/view-all

I'm at a loss as to how to fix that.

I am not certain but I think you are supposed to use a combination wye 1/8 bend


But that still doesn't fix the structural damage. The pipe is too thick to go through the joist.

Edit, Ok. I was posting when you replied and I didn't see your reply until after. I really have no idea. I don't know, I guess you can't add a bulkhead in the floor below and try to make it look decorative? Or perhaps raise the floor in the existing bathroom? Is that a joist directly under the wall? If not you might be able to put the wye in there and sink it down. OR you can have it on top and then raise the floor level. That may not be ideal, but it may be easier than having to mess with the ceiling of the room below.

you also cant use a 90 on its side ( the tub ) your wet vent serving 2 tubs is also incorrect, you cant bump a wet vented portion of pip up or down it must stay the same size throughout the vet vented portion. ( i refer to the original pictures where the pipe changes from 3" to 2" )

and, as others have said. That joist is messed up.

Rip it out. Hire a licenced plumber and save money. And whats up with the end cleanout on the double wye? Thats a leak waiting to happen down the road. Put a permanent cap on that.
