460 unit #1 : technician was called out to this unit because they heard gurgling coming from the bathroom toilet. Will technician he ran the tub and flush the toilet a few times nothing was backing up and the toilet was not gurgling. That could be an indication that the clog cleared itself. Technician will still give the customer an estimate on pulling the toilet and snaking the line. 480 unit # 2: the issue with this unit is that the cast iron vent stack has a crack in the line, causing water to leak into unit #2.

(Maintenance worker went to the top floor above unit two and did not see any water damage or cracks in the pipe. But technician may still have to get access to the unit above.
