Why kitchen lines fail
- Hot grease rinsed off pans cools and coats the pipe wall.
- Food scraps settle in long horizontal runs under the floor.
- Undersized or skipped trap service lets grease pass into the building drain.
- Dish machine water pushes soft grease further down the line.

Keeping it working between visits

Straight answers to common calls
Can you clean the trap during service?
Small under-sink traps sometimes can be. In-ground interceptors and jetting are best done before opening or after close.
How often should a grease trap be cleaned?
It depends on volume. Many busy kitchens need monthly service; we can help you set a schedule after the first inspection.
