How do you vent a kitchen sink in an island?

There are several ways, but the only one you should be concerned about is which one the inspector will approve. Find out before piping it, because it is often a pain to revise it. hj

JoeB:---An island Sink can be vented in two ways.
Old way...increase the branch line two pipe sizes
(3") and make a bumper stack under the
New way...Use standard pipe sizing, and vent with
a Studor type vent.
Both need the blessing of the inspector if this is to be a permitted installation. Good luck with your project..Ahr
