Is a vent or air admittance valve required when a kitchen sink drain is connected to a four inch drain line? The builder says "no", but I thought every fixture required some kind of vent.

You thought right! Although, an AAV would probably work here, it is usually required to have a 1.5" vent going back to the main vent stack.

This might help.
http://www.nachi.org/plumbingcoursereleased2008.htm Jump to "Vent Section." I think that it's a good course, but I'm heavily biased. |

Thanks to all for your quick replies.
The things that some builders say to justify poor workmanship never cease to amaze me. |
