Plumb Washer & Laundry Sink Into Existing Stack


Want to install a laundry sink and washer as shown in the photo. Can I just remove the existing 4"-T from the stack, replace it with a "Double Sanitary T", use one tap of the San T as a clean-out and the other tap as the run for the sink using a wye then onto the washer?

Also will I not need a vent for the sink/washer since it will be close to the stack?

Check out photos and let me know your comments of a better way

That'll definitely work. What I would do though is stack 2 sani 90's on top on each other, cleanout (facing out) on the bottom and the drain (hanging a left) above.

I like that suggestion about stacking the San-Ts. How would you go about venting?

If your washer drain box is within 5 feet of the stack --no additional vent will be required---

One of the licensed plumbers will correct me if I steered you wrong.--Mike---

I pulled my code book so I could give you an exact answer. The maximum length for the trap arm (drain from washer to stack) is 2.4m (7' 5"-ish) assuming you're using 2" pipe as the drain.
At least up here it is, your local codes may vary so you might want to ask the local authorities to be certain.

hey guy nice drawings...yes this will work and i believe in ohio if you are within 6' of stack you don't need vent....I would cut a tee under the existing clean out and be done with it....

Ben...when you say tee....you mean a wye-T correct.

And it does not matter that the cleanout will be slightly ABOVE the wye-t. Or should I rearrange and put the cleanout lower than the wye-T

You will be fine either way---t or y---however,I like VIPs suggestion--having the clean out T facing out will make servicing the line easier---and will be in the correct place if the wall is ever studded out for a finished room.

Plumb Washer & Laundry Sink Into Existing Stack


Do you think I need the re-vent since the sink stub out will be only about 24" from stack?

If I can eliminate the re-vent, I could take fitting #2 and rotate it so the branch of the T-Wye is the stub-out for the sink and then the run of the T-Wye would go and pick up the P-trap for the washer standpipe.

How does this sound?
