1.5" vent and revent

lmei007 · May 24, 2011

My 1st floor tub drain has a 1.5" vent. I am thinking move and add a vent for my basement counter sink horizontal drain. Can I connect the planned vent to that 1.5" vent? thanks,

You can connect the two vents together at 6" above the highest fixture flood level.

Technically, the requirement is 6" above the highest flood level OR 42" above the floor whichever is HIGHEST.
