Okay, thanks, I just wasn't sure if it was allowable to basically have an abandoned vent pipe connected to the drain stack without an actual trap arm as well. Logically I can't see where it would cause a problem, but I'm not a code expert so I was concerned it wouldn't be permitted by code...

I am removing a sink from an existing basement location and don't have any immediate plans on replacing it, so I have to do something with the existing lines. What to do with the soon-to-be abandoned/unused drain is fairly straightforward because I have access to remove the drain pipe back to...

I'm in the midst of a kitchen remodel and am adding an island with a sink where previously there was none. I'm familiar with the idea of island vent loops and generally would prefer to do that rather than use an AAV to vent the island sink. However, in this situation, there's insufficient...

Thanks Asktom. Unfortunately, while my simplistic drawing shows the existing basement vent pipe in the same wall as the 3" waste stack, in reality, it's on the other side of the room. To get the new vent connection from the standpipe to the existing basement vent pipe, I'd have to tear out the...

Okay, thanks for the quick response. I saw some responses in other threads here suggesting that AAVs weren't allowed by some codes or, even if allowed, aren't ideal for pump discharge like on a washer due to the fact that the sudden high volume of water creates back pressure in the rest of the...

Okay, I've done a little more digging and come up with an alternative to an AAV. I'm familiar with island vent loops and could do something similar to vent the washer standpipe and want to make sure that's kosher. Effectively, I'd have the washer standpipe drain into the existing 3" waste...

Not the answer that I wanted to hear, but thanks for setting me straight. That brings me to my next question: How do you feel about my using an AAV/Studor valve to vent the washer drain? Putting in a dry vent would require a good bit of demo and drywall repair. I'll have some deep cabinets...

I'm about to start a laundry room remodel on my house's first floor and would like to move the washer and dryer. The location the washer would be moved to is on a wall that has a 3" waste stack servicing one (and only one) bathroom ( with a tub, toilet and sink) on the second floor above the...

Thanks HJ! I figured as much so it'll just come down to what parts I have available.

I realized my question above in post #5 about moving/modifying the right drain stack was a bit hard to understand, so here's a sketch of what I'd like to do to be able to move the right stack even further to the right while keeping the part where it 45's back to the left drain/vent stack from...

HJ you're right, there are two tees. The upper tee is going to be removed and that's where I would tie in the tee for the washer drain line. I'm still concerned that keeping the right drain stack arranged so it ties in on the 45 might make it tight to put the washer drain ptrap in between the...

Thanks for the quick reply Terry. Am I correct in my belief that I'll need to add a new vent connecting the sink drain line to the vent stack on the left above the point where the washer drain ties in? Also I'm a little concerned that maintaining the 45 on the right drain line (especially...

I'm aiming to add a washer outlet box drain line to a wall that currently has a sink drain line, vent, and drain line from the floor above and would like to get some advice on the best way to re-do the drain/vent lines. I've attached a photo showing the existing situation. These are all 2" ABS...
