Kitchen Island Vent
We are installing an island in our kitchen and the first plumber we had told us we did not need a separate vent for the island sink. He told us that connecting the island drain to the main drain and vent would suffice (first picture is what he did). I realize we need a cleanout with the drain, which will be installed after the cabinets.
Now, our new plumber told us we do need to vent the island sink or it "would bubble and have problems draining". However, our new plumber did say he could connect to the vent from the main sink (see picture) which is in the wall (trench already cut in wall to left of window). He told us he would "install an upside "u" with a cleanout for the vent and go back into the floor, through our crawlspace on an upslope and up through the exterior wall to connect the existing vent".
Which is correct? If we need to vent the island, will the upside "u" be the way to go about it? Finally, can we connect to the existing vent?
Our state only has a final inspection on a remodel so we want to have it right before they get here. Thanks!

vent
The upside down "U" would be the way to vent it, but it takes more than just that and a pipe to a nearby wall.

Thanks for your help but when we searched for kitchen island vent or any combo thereof we found no results.
Who is CM?
Can you provide a link to this post?
Besides a cleanout what else?Originally Posted by hj
Possibly this will help.

vent
A "foot" connection to the drain from the vent, a cleanout in the vent riser in the wall, a properly sized, (2"), vent line under the floor.

Thanks gentlemen!
studor vent???
I dont know where you live but in the mid-west
an auto air vent is ok under a kitchen sink
they are called studor vents, aout air vents
it might be ok for your area,
it sounds like you canned the first plumber
but he still might have been correct about this..
we use them all the time
