water backup in sink
Posted by jane pankew on September 09, 19100 at 19:21:54:
when the toilet is flushed, water gurgles up in the sink. clog was suspected so drains were treated with
liquid plumber. toilet and drains work fine. this has happened in the past but it went away.
the basement drain has backed up twice before and the city snaked and found tree roots, but no
flooding at this time. sink and toilet are on the main floor. whats up?
thanks, jane
