He can come out to the sink with a 45, just makes drywalling it a little pain but snacking easier.

Ok i think that makes sense.

In my scenario using an AAV, referencing that drawing would the AAV go on top of the Wye basically?

Re: Cant remove this nipple from main stack


whew; you all have been busy wood chucks...

sure would have been nice to know you have a 2" PVC
vertical drain to left of metal stack you could have tied into...

your old washer drain most likely did not back up because
it was immediately wet vented through that larger drain pipe...

No; the L/tub should not be trapped if you are using the washer trap.
place a cleanout INTO your L/tub drain where it turns horizontal;

your problems with the new drain branch are it is undersized
& the 90` turns near metal drain stack are not long sweeps -

also I can not tell what amount of slope/fall is on that 1.5"
horizontal drain line; that said - your saving grace is going
to be the capacity of the L/tub should contain any back ups

It would have been simpler to place a 2" drain line behind you wall
tied into the 2" vertical PVC drain, of course vented with an AAV
& incorporating long sweep changes in direction... with good slope/fall

Peace

it is an exception in code - think of a double or triple bowl sink
where the 2-3 outlets tie together before being trapped...

I can still tie into that 2Ē PVC but truthfully I didnít think it was a vent?

It has a sink coming off of it behind the wall that you canít from what used to be a basement kitchen. From what i see that sink is only wet vented to that pipe so itís not a vent like i need is it?

In pretty sure itís the drain to my bathroom sink.

I knew beforehand it was undersized at 1.5Ē. Problem is that putting it inside the wall with an outlet box was an afterthought. I mentioned making it nicer to my wife and of course thatís what she wants now...

It obviously isnít to code or being inspected regardless but of course i donít want to have problems either.

As far as the elbows go, I need to use a long sweep to create better less turbulent drainage Iím guessing?

Are full 90s no good in this scenario in general?


Before i forget thank you all youíre a huge help. Iím a carpenter not a plumber...

Re: Cant remove this nipple from main stack


I can't follow 50+ posts but it's this simple
The drain is 2"- exceptable by UPC
Wet vent the sink into vertical 2" washer vent
AAV goes on the vent above the 2 fixtures

1/4 turn 90s are not allowed for turns horizontally
2 45s together or the equivalent us what is required...

Just noticed the drawing i didnít see it prior

So in this scenario i need a p trap below the washer box and one under the sink correct?

Also i need to change out the elbows to long sweep ones?
