I have a free-standing kitchen island which houses a smaller food-prep sink.
Since venting vertically would have been impossible I decided to drop the 1.5" abs drain down through one of the hollowed out legs and place the trap below the floor.
That way I can 'T' off after the trap to connect to a vent that travels up through to the attic inside an interior wall.
Problem I see would be if any objects fall down the sink drain and become lodged between the sink and the trap (inside the hollow leg).
Should I install another trap directly under the sink to catch fallen objects?
Will this affect the performance of the second (main) sewer gas trap beneath the floor.
