I am wanting to relocate my kitchen sink. How far away from the 3", main waste pipe can I run my 1 1/2" sink drain, before it requires an additional vent pipe?
Your help is appreciated

Cool

Contact your local Building Inspection Department for local code. They should be able to tell you, after you give them specific distances.
Good Luck!

Vent requirements

Code Check-Plumbing-Vents
I just completed the rough on the plumbing for an addition. I used a wet vent for the sink. In my case I could use the drain for the sink as the vent since it was less than 42" from the main vent for the bathroom. Reason being: more than 42" and using the 1/4" per foot drain, the vent opening will be closed. Use the link to Code check. A great site for building, plumbing, electrical and some mechanical codes. These are generic per association governing the trade. Local codes may(will) differ.

You might be able to use an auto-vent, if you can't make your 1/4" per linear foot slope in the drainline to the stack.
It installs in the drainline under sink (after the trap).
Good Luck!
