Restaurant Grease Line Maintenance That Prevents Closures
Why food service drains fail during service, how often grease lines need jetting, and how a maintenance interval costs less than one closure.
In a commercial kitchen, drain maintenance is an operations cost with a predictable interval. Skipping it does not save money, it converts the cost into a closure at the worst possible hour.
Why grease lines fail
Warm fats, oils, and grease flow easily through the trap arm, then cool in the horizontal run and adhere to the pipe wall. Detergents emulsify grease long enough to get it past the trap, which is why aggressive dish chemistry often makes the downstream problem worse rather than better.
What a maintenance program includes
- Scheduled hydro jetting of kitchen branches and the main grease line
- Grease trap service on an interval matched to volume
- Camera verification so the interval is set by evidence, not habit
- Floor drain and mop sink service, see floor drain cleaning
- Documentation suitable for health inspection files
Staff habits that extend intervals
Scrape plates and pans to the bin before the dish pit. Keep a fryer oil disposal routine that never touches a drain. Use drain screens at every prep sink. Train new staff on it in week one, since turnover is the usual reason a clean line degrades.

Common questions
FAQs about Restaurant Grease Line Maintenance That Prevents Closures
How often should a restaurant grease line be jetted?
Most kitchens in our service area run a 3 to 6 month interval. Volume, menu, and pipe age set the number, and camera footage after the first two services tells you which end of the range you are on.
Can you work outside service hours?
Yes. Commercial drain work is scheduled overnight or before opening as a matter of course, not as an exception.
Is a grease trap the same as the grease line?
No. The trap intercepts what it can and needs pumping. The line downstream still accumulates, and it is the line that closes a kitchen when it backs up.
