Service at 6-plex. Worked for ~ 15 years. Knockout plug left on end of 4" ABS. Had a chunk broke out of it, like it plugged up right away and someone poked it with a snake. ~ 60% of flowpath blocked. I keep finding these incredibly messed up things that somehow worked for a long time. Makes me think that drainage systems are, really, shockingly robust.
