Hi, I was wondering if anyone had a picture or sketch of a drain with an AAV. Just want to make sure what I have is right.

Thanks

Here are 2 examples of AAV installation... (Edit: I have substituted first diagram with what I believe is better way to go )

I can go with Milo'as 2nd pic but the first one is like spitting into the wind. The washer is darining into an open ended stand pipe above a trap, no AAV needed with this design, the air just enters through the stand pipe

Ok, so here is what I started with :

And here is what I finished with:

I am not sure if the bend is too narrow going from the washer drain through the P to the stack? I ran the washer and it went down fine without a problem, what do you think... also, I put a rubber seal from the washer hoe to the stack, any problems with doing that?


That didn't seem to work, here are the links:

Bob, You said,

Ad,
Photos #1. 2 and 4 show a illegal hook up, I see a direct connection to the city sewer without either a trap or a vent.
However , photo #3 shows both a trap and a AAV such as Milo pictured. That's your keeper. Good luck, Tom

So, 1 and 2 are the way it was...

3 and 4 are the new setup, though 4 is sideways---sorry about that...

What you can not see is that even before it didn't tie into the main sewer it tied into a sink's p trap... it was a very odd setup...

But it looks OK now? Even thought there is a harsh angle for the water to travel the almost "s"?

Yourtrap is more of an S than that"harsh" angle. Lloks fine to me. What does this drain into, looks like maybe a sump pump pit or something.

In pic three and four, you have installed the trap and aav just as any plumber would have. You are good to go. Good job.

Nope that's my first floor, it goes down through the subfloor about another 5 feet into the basement, then it travels essentially at a zero pitch 6 feet, then makes a 90 degree turn through a wall 12 inches, then another 90 degree turn and on for about 6-7 feet at about a 45 degree pitch then connects to a utility sink (above the sinks P trap) draining out with the utility sink (again at almost a zero pitch in a big square to the main sewer line).

I know it is a cluster... but Im tackling it slowly but surely one step at a time!

Sweet, thanks!

Good job !

Thanks, I wanted to show you guys what's below the washer and the next step in the project.

This is the room below the room the washer is in:

Here is where it punches through the cinderblock wall:

You can see where I have marked it for cutting to replace with PVC and tie in the washer line.

The next picture shows it progressing through the cabinetry towards the drain tie in that was done before I bought the place.

And finally the wacky tie in:

So what do you think of the plan?
