Thread: Vessel sink venting?

This place had vessel sinks installed with food diposal tail pipes with rubber hoses attached. Appears to be an effort to improve draining and venting. Is this allowed or accepted, have never seen it before.

Of course not, don't be fooled by new "vessel sinks". They have the same drain requirements as traditional sinks.

All I can think of Mr Chekoff telling Capt Kirk "there is a wessal off the bow".
