By MarinaSeptember 13, 2019plumbing in the bathroom leak from second floor
very bad plumber.
I had a leak from second floor, plumbers fixed it and while fixing the leak
they didn't bother closing the main valve so the water would stop flowing
plus they broke the floor of the second floor apartment while fixing the pipes and dumped all the debris on top of my sealing, guess what: the ceiling collapsed and all the debris fell in to the toilet than G-D no one was using the bathroom.
2 weeks after "the fixed the pipes" it started leaking again from different place and right between the wall. and I am still waiting for them to fix that problem going on 4th week already.
I am planning to sue the management for sending such plumbers.
