    kitchen sink plumbing/vent problem
    good morning to all!
    I have a question that I hope someone can answer.I have an older modular home that we've decided to upgrade the kitchen in.I'm installing new cabinets and a new sink and also have decided to add a dishwasher next to the sink base cabinet.my problem is that the vent that goes into the wall and up through the roof is right where the dishwasher needs to go.at this point the walls and ceilings have just been done so relocating the vent in the wall isn't really an option.the contractor that I had here doing some of the work suggested capping off the vent,cutting it off at the wall and installing what he said they used to call a boka or booka? Vent that goes under the sink.he said it had a check ball in it? I'm lost!! Wouldn't venting it under the sink give me sewer fumes/gasses? The existing vent is right next to the wall studs next to the window over the sink (its all open right now-no sheetrock) and the only thing I can think of to do is cut the pipe and I'd have to put an elbow on it to move the entry point in the wall over 8" but that would require going through one of the wall studs and they're only 2x4's.any help would be greatly appreciated!
    thank you,
    dave

    And a good morning to you too Dave,

    You plumber wants to install a AAV, (Air Admittance Valve) witch is a spring loaded mechanical vent . Click on: http://www.studor.com/homeowners.htm to see. It would be better to offset the vent and use the roof vent even itf it meant taking it through a 2 X 4.
    However a AAV will not allow sewer gas to escape in your house as it only lets air come in and not go out. The only problem I have with AAV's is if they fail it will for sure allow sewer gas in your home.
    Having said that, and if there's no other way, a AAV's acceptable to replace a outside vent. Good luck, Tom

    Thank you so much for your info! I've checked out that website and emailed them about a price.I'm going to try to use the vent pipe that's there now-i've just got to figure out how to move the entry point over without reducing the integrity of the wall studs.
    Thanks again,
    Dave

    Yes it would put out some nasty smells... revent it if the pipe is galv. Before cutting anything look at it and see if what kind of pipe it is. If it is galvanized pipe look to see if you can cut the pipe and relocate the vent. As long as it vents out the roof you are doing good. If you have room under the sink to relocate the line to the old one then you will be doing good. See if you can cut it one the side where the dishwasher is at and right above the dishwasher reconnect it. If that will not work you are going to have to take that part of the wall out and have it redone. That is the only way that I can see for you to revent the stack because you HAVE TO HAVE THAT STACK/ VENT.

    Bear,
    Did you miss the part where he says he has a modular home. You won't find galvanized pipes in a modular home, only plastic. Dave has already decided on a AAV so your advice about reventing, while good, is a little late. Regards, Tom
