Shared Bow Vent......

[Desert10]

As part of a kitchen remodel we’re enlarging an island to include a small prep sink. The island already has a double bowl 36” wash sink that is vented with a bow vent. Are there any issues tying in the new prep sink to the existing bow vent. My plumber says not but just checking……..

I have never had to do it, but cannot see why it is not possible, assuming pipe sizes are adequate.
