My vent for the sink is on the old wall, the wall that I will be moving the sink to only has a inch and a half galvanized drain from the tub above on it..,no vent that I see anywhere IS it safe to assume that the vent for this tub drain is maybe below the floor somewhere in the basement??

Lastly, I will need to vent the new sink in it's new location, I know that the old wall has the vent for the sink but how can I tie this into the new sink being located on the opposite wall??

Thanks again for all your help Tom,

Regards,

Harvey

The vent for that tub drain you are mentioning is the main stack that goes thru the roof. If your tieing in the new sink on that same bathtub drain it's already vented. I would not worry about a seperate vent. If your concerned about it that much, install a studor type (cheater) vent. And yes, since you have the ceiling or floor exposed and you can get to the plumbing easily, install a new waste and overflow drain on the tub. They make them in PVC and if you need help with that, post back.

Hi Tom,

I was told about some kind of siphoning effect if I tie in my new sink drain to the exisitng tub drain?

Like you said, the tub drain is vented already so I don't see a problem vent wise but I Was told the tub drain would siphon the water in the sink p trap??

Keep in mind the p trap for the sink is a few feet over to the right. IOW- there is a horizontal run that goes through the studs before it gets to the y connector and ties into the above tub drain.

PLease tell me this will be ok??

thanks in advance Tom,

Harvey

It might Harvey, good point made. Get a plumber to come in and look at your situation. Let him explain to you how to make the connections properly by code. The cheater vent I mentioned before is usually not allowed by code. Some plumber's sneak them in sometimes if it's a long run, etc;etc. Of course you will have to pay for the consultation, but you will be in the game. Good luck.
