Hi! I had a leak in my basement coming from what I thought was the cold water line going up to a sink in the bathroom. I took the wall apart, exposed all of the pips and that was not the problem.

I did find the leak though, I'll try to explain it:
1. The waste line going down to the basement has a 'T' attached where the waste from the sink enters and exits (2 of the 3 possible connections from the 'T')
2. The top of the 'T' is connected to a junction which connects to a second 'T.'
3. This second 'T' is capped off on the top, but the side has a junction connected to an elbow that had a small tube (looked like aluminum from the sink drain type stuff) with a whole bunch of garbage stuffed into it - this is where my leak came from.

I took the elbow with all the garbage off, capped the junction and now water does not drain from the sink. I realized that I needed some sort of vent and read about the DWV in a home projects book, but don't know how I would be able to attach this piping to the vents that leave my house, this bathroom is on the first floor of my three story home.

I was told about some 'in the wall vent or quickie vent' and I was wondering if these are allowed/legal? And how to best go about installing one? Or is there another way that you recommend that I vent these pipes.

Thanks so much for your help
Jim

Hi Jim,

Your explaination's a little confusing. Could you post a picture of the drainage set up? You're asking about a AAV,(Air Admittance Valve) (see image) This "cheater vent" would install on top of the uppermost tee if local codes allowed it. Regards, Tom

Tom,
Thanks for your help. I figured that my explanation was wordy and confusing. Unfortunately I do not have the ability to take a photo and post it on the web. I am going to see if home depot has one of these and try to attach it. As long as it is higher then the uppermost tee it should work, right? Thanks again
Jim

The AAv I put up is a Studor Vent and can be checked out at; STUDOR (R) inVENTive Technology (TM) - Air Admittance Valves Good luck, Tom
