Venting kitchen/laundry.


Hello, my kitchen sink gurgles when I run the washing machine and my guess is the lack of venting is what is causing it. From the top down, the kitchen sink has 2 drains that come together at a T with an S trap underneath going straight down to the floor (all 1.5 inch PVC) where it attaches to a 2 inch cast iron line going to the basement floor. Just above the floor is a 2 inch cleanout with a 2 inch PVC pipe screwed into it going to a P trap with an open ended vertical pipe for the washer hose. No vent.

The washer would be easy to tie into the current vent pipe in the basement (just have to add about 40 feet of 2 inch PVC and tie into that cast iron vent line) but to do the sink I'd have to run it down into the basement and across and then back up and out.

Do I need to vent this? Both the washer and/or the sink?

Good guess.

Of course you do.

I'm not taking the time to decipher your description of whats there... The only question is how to run the pipe up through to the attic and how to attach the several drains along the way to that pipe.

Ok, I will vent these. To vent the sink I'll have to run the pipe down to the basement and attach it to the vent for the washer. Is that alright? The only other way I know to vent that sink to the attic would be to either cut holes in the cabinets and counter to run it along the wall or pull out all the cabinetry and that one piece counter to get access to the wall. I keep seeing posts for an AA- something (but haven't come across what it is yet). Is that something that could help here?

Vents are supposed to be above the drain and therefore hooking your sink vent into the washer vent by running it downstairs is a no go.

What may help you out is what is known as an AAV, automatic air vent. While it may be helpful to you you might want to check with your local inspection dep't to see if they are permissible in your area.

Ok I found some AAVs online for $15-$20 but they say: "for secondary venting." Does that make a difference? And do I just cut in a T and install it on the new opening? I am unsure how to get it above the drain as that is the highest plumbing in the house aside from the main vent line on the other side.

I'm trying to get a picture up here but I don't know how to get it here. I had to draw it on my PC but I don't know how to get it onto my phone to upload to the Internet.

Where under the sink should I attach the AAV? I can put it above or below the trap using a T and an elbow.

As for the picture, I know how to upload it from my phone but loading it from PC to my phone is the hard part.

It should look like this. The red dot is the AAV.



Or this.

Awesome, I will do that (assuming its permitted).

Now the only hard part left is cutting in a T into that cast iron vent pipe just upstream from the toilet elbow.
