first go out side lift and check the man hole that serves your property for a blockage/backup (YOU WILL TELL NO SOONER YOU LIFT THE COVER)DRAIN RODS WILL DEFINITELY BE NEEDED FOR A BACKUP PROBLEM AND MARIGOLD GLOVES. if clear problem is between the bowl and the manhole, could rod the using a big plunger, or the bowl needs to be took out and rodded through to the MANHOLE
If a backup problem you need to rod from the manhole to the main sewer.If possible FIRST check ALL the manholes on the run to the sewer.
