In response to Re: Kitchen sink venting issue!! need help and opinion.
: : : I have a contract signed for a 4 family home and it turns out that none of the kitchen sinks are vented... When you run water for awhile and fill up the kitchen sinks and then release the water a gurgling sound is heard like it is sucking for air.

: : : Are there any dangers to not venting and more importantly, short of breaking throught he walls to install a venting system is there anything else that can be done to cure this issue??

: : : I have included "fix non vented kitchen sinks" on my home inspection report to sellers attorney. But realistically I doubt very much he will break through the walls and poke through the roof w/ a venting system due to costs and labor so I am hoping there is an easier method to doing this??

: : : Lastly if sellers refuse to fix anything do you guys think thsi should be a deal breaker??

: : : thanks in advance,

: : How did you determine that the sinks were not vented if you do not have access to the walls?

: By the gurgling sound it makes when the water goes down the sink drain. Also, by looking on the roof and attic and not seeing any vent holes popping through.

: Assuming there was no venting how would you proceed deb??

: Thanks,

I would not assume that there was no venting (is this a double negative? ;-). A partially clogged drain will cause the problems that you are describing. Kitchen vents can combined with other vents and not be readily discernable.
If there actually are no vents, this needs to be rectified prior to closing any deal. You may be able to run them on the outside of the building and then box them in. You may be able to make a horizontal run through the cabinets to a closet or pantry. I would not recommend an auto vent.
