I'm installing a loop vent for an island sink. This is for a room addition. I would like to make the loop vent waste connection up stream of the sink waste connection. The two books I have show the vent return to the waste line down stream from where the sink connects to the waste line.
Does it matter where the loop vent connects back to the waist line?
Could it even be a different waist line than the sink it is servicing?
