Moving a vent in the wall.


I am installing a sliding glass patio door in my kitchen. The door that is there now is NOT a sliding door. So... Gotta cut a new hole in the wall and new header and studs. Blah, blah. That's not the problem. I tore into the drywall in the kitchen and realized very quickly that there is a vent pipe in the middle of where the door needs/has to go. I am NOT going to start a roofing project to move this vent's exit location. What are my options. Keep in mind that there will be a 2x12 header where the vent goes up the wall and to the roof. This is a two story house. I will try to send pics. if needed.

if it is PVC elbow away from the sliding door then come acrss the top to reconnect to the exsisting vent riser... if there is a basement relocate where it rises into the kitchen then up elbow over the top of the slider..even consider bush it down for the trip around the slider..just throwing out stuff...might be a law in your state that you can't size down a vent riser..forget the roof it's do able inside totally

The vent needs to exit through the roof. 2 ways around it- use an AAV on the fixture in the basement and eliminate the vent-assuming they are allowed by your local code. Or reroute the vent to tie into another vent stack.

Is an AAV a one way check valve?

Do a google search for studor vent or AAV
I recommend trying to reroute the vent first.

Be careful with those things. I hate them, as does my inspectors. If we can vent in a typical method (no matter how difficult)- we do.

I think someone should put a censor in for AAV and studor vent on the forum.

Yup. I did more research. I won't be using an AAV. I always want to do the right thing and you reminded me of that. Thanks guys.

I don't get the hostility toward AAVs. They serve a legitimate purpose if a fixture can't be vented any other way, and are perfectly legal (here anyway). My kitchen sink is vented with one, and there has never been a problem.
