Slow Drain - can’t find a clog
Slow kitchen sink drain. Took off p-trap, no blockage. Inspected disposal unit, no blockage. Everything looks free and clear into the wall.
Takes about 30-45 seconds for the drain to back up into the sink.
Kitchen is on first floor above a basement. Main drain is shared with half a dozen other sources, none of which seem to have issues.
Any ideas?
