Always let cooking grease cool and drain into a container instead of your sink!
Wipe out cool pots/pans/griddles with paper towels and dispose of them in the trash.
Restaurants: hang a “No Grease” sign above your sink as a reminder!
Use a sink strainer to help prevent food particles from entering your drain.
Regular backups and slow draining at multiple drains like the sink, toilet and bathtub are telltale signs of an issue with your main sewage system.
Most backups are created by a buildup of debris, grease, etc. in the sewage pipes.
If the issues persist after snaking or jetting the pipes, there is likely a break or leak that needs immediate attention.
