Think there was a post or two commenting that roots got into the drain
then water leaks eroded the soil underneath allowing the drain to drop
and cause subsequent problems. Had a plumber here recently for slow
sink drain and he insisted on sending his new camera down the mainline
for show & tell. Found a few small roots that we'll take care of with
the semiannual Root Kill flush.
