the only thing I left out here is I will put a 2x2x 1.5 tee after trap for the vent to go straight up.
So does that look good? thanks

Hi Mike

You don't need the stack going up like you have...see my picture. That is, unless that stack is existing?? If it is, then I need to know if it is connected to the downstairs bathroom??? Let me know, OK?

Otherwise, as drawn below, you should only need the one 2" vent to vent both the tub and the sink, right? I understand your wall isn't deep enough, so if you must reduce to 1.5" pipe then do so, but if a permit was pulled, the inspector would just tell you to "pad the wall out an inch and put up new drywall" to keep that vent 2"...

Note, that the vent needs to roll above the centerline of the tub drain to be a vent...even if it is a wet vent.

Send a 2" drain to the lavatory if you can as this at least gets you as close to code as you can get, again, considering your wall isn't deep enough for a 2" drain/vent pipe.

I didn't understand this--->>> "the only thing I left out here is I will put a 2x2x 1.5 tee after trap for the vent to go straight up"...? Here, the tub vent acts as the lavatory drain and the lavatory vent...it's what makes the tub "wet vented" by the sink, so you don't need the additional 2x2x1.5" tee fitting, right??

Back to you...

Mark makes valid points. I like his layout much better. Since you won't be venting the lavatory from the trap will you be installing a "S" trap on the lav? Regards, bTom

Thanks Mark. Really appreciate your help.
No the stack is not exsisting there. So I will go with your design. I just have to support the wall where the 2" pipe will go through it. I will keep you posted as I do the work.

Hey guys can you tell me if this looks okay? this is the trap for the bath and the hole is for the 2" lav to come down angle around and join into the Y there. The lav drain runs up to the 2" P-trap.

They are just dry fitted for now to show you, waiting your opinions before glueing them together.

Hi Mike


Cement 'er up...looks just fine!

If possible, connect a TEST TEE (see image) cleanout somewhere either after or before the tub wye, OK?

Mark

PS: The image shows a black ABS cleanout...obviously, you want PVC.

Mark, how is that fine. Not only is there a running trap, but also an s trap. Vent is nill and void here. Not often, if ever do I disagree, but this wouldnt pass anywhere. Take a closer look.

I would suggest using a pvc waste and overflow so you can use some 45s on the overflow to get past that joist. Then drop straight into the trap, (as Mark drew it up perfectly). The sink drain(whick will also serve as the tub vent) will drop into the wye like you have the tub drain dropping the wye in your pic. Hope that makes sense. And I hope you havent glued it yet.

Hi Lee...

It looks like he used an ABOVE THE FLOOR ROUGH IN tub waste and overflow assembly. Here, these are rare, but when used I notice that most inspectors allow them in place of cutting out/heading off joists (check out the double joist in his picture where the tub waste would be if he used a regular tub waste), but I certainly see why you mentioned what you did...

I didn't see an alternative, besides heading off the joist...unless he added an individual vent, of course, but as I've used a few of these above the floor rough ins over the years, this seemed OK.

In terms of the STRAP...I am guessing you are talking about the sink? That should be vented with a 2" vent here so it should be a PTRAP going in. If not, and you are talking about the tub trap then yeah, he certainly could lose the street fitting coming out of the wye and roll that wye flat...WOULD DEFINITELY BE A BETTER JOB, FOR SURE!!!

Back to you...
