    Hi Gypsie...

    They make a mechanical vent, called an AAV (air admittance valve) that can be used in place of the vent that is there now.

    With that being said, however, the AAV is not accepted by most plumbing codes so if you want to stay code complaint (can be important if selling your home, for example) this may not be an option for you.

    If AAVS are code legal in your area (would need to call a local plumbing inspector to know for sure) then you can install it under the new sink so it remains "readily accessible" in case it fails and needs to be swapped out years from now, OK?

    Bottom line is that an individual vent as is present now is the best way to go as you have no mechanical parts to fail, but as a last resort AAVs do work.

    Check out some of the images below. Let me know if you have questions...

    Hi Gypsie...

    I'm sure they sell them and I'm also almost 100% sure NY won't allow them to be used, even if they are sold locally. Here, in my area they are sold, but they are also illegal and a homeowner may be able to install one (illegally), but a plumber could never get away with it.

    My best advice, it being NY, is going to be to find a way to connect onto the old vent or even better, see if you can find a new, shorter route to run a new vent. If you can't run a new vent know that someday when you try to sell the house you may be called on an illegal vent (AAV) and it would need to be removed and a new vent run then!

    If you have more questions please type in the box at the bottom of this page and post that way so all can read up, OK?

    Thanks...
