"Tapping" into 3" soil stack for a sink drain?

Is it ok to tee into a 3" soil stack for a wetbar sink in my basement?

I have 2" PVC running from the soil stack thru the studs to the sink area.

Also I have a lot more than 1/4" fall per foot...is that a problem?

See pic 4 page 3 of my site.

Thanks FF

Pic 1,
Looks like you have a low voltage line Coax (TV line or something phone) running in the same hole as some 120 Volt wires.
You may want to ask someone in the electrical section about the code. But its not a good idea, the 120 volt line may put in interference in the (any) low voltage lines, coax has less problems but I would keep the distance over 12" from any"

-----------------------------------------------------
I think you also need a vent for the sink.

Thanks for the reply.

You are right on the coax (12") the one that is there is just temporary for little tv I use/listen to while working. The permenent coax will be 12" away min. in separate run.

When you say a vent for the sink.... There is a vent connected to the "soil stack" on a horizontal run in the joists right above the wetbar sink.... is that adequate?

Thanks for any help.FF

I would be concerned about the slope of the 2" drain. Too much slope can actually drain your sink trap and you'll have an open pipe direct to the sewer stack.
