A commercial kitchen maintenance checklist helps turn grease trap and interceptor service into a repeatable process instead of a reaction to odor, slow drainage or a missed visit. Use this guide to keep equipment information, access, observations and records organized between professional services.
Commercial Kitchen Grease Trap Maintenance Checklist
This checklist is operational guidance, not a substitute for the facility’s FOG BMP, equipment instructions, professional inspection or the requirements of the authority with jurisdiction.
Six items to review between service visits
Equipment record
Keep the unit type, capacity, location, manufacturer/model if available and a simple identifier for each trap or interceptor on the property.
Ready access
Check that lids, ports and exterior service areas are not blocked by storage, parked vehicles, landscaping or temporary equipment.
Operating changes
Record menu changes, new cooking equipment, additional shifts or major volume changes that can affect grease production.
Warning signs
Note new odor, slow drains, gurgling, visible leakage, backups or recurring problems rather than waiting for staff to remember them later.
Cleaning records
File the cleaning date, grease and solids removed, reported condition and any corrective action with the facility maintenance records.
Next review date
Schedule the next review based on applicable requirements and the latest service findings instead of relying on a forgotten calendar reminder.
Access is part of maintenance planning
A provider cannot perform the planned scope efficiently if the service lids or pump-out points are blocked. Columbus City Code 1145.04 specifically addresses ready access for interceptor servicing and requires exposed, unobstructed service lids. It also addresses exterior service space for gravity interceptors and remote pump-out capability for certain indoor hydromechanical interceptors. Review the current City Code 1145.04 document when the facility is dealing with design or access questions.
For day-to-day maintenance, assign responsibility for keeping the service area reachable and for telling the provider about unusual access before the appointment.
After each cleaning, close the loop
Update the log
The City publishes a BMP packet and interceptor log through its Sewer Forms page. Record the date and the relevant removal/condition information after service. Keep the record tied to the correct unit if the property has more than one interceptor.
Track corrective actions
If a provider reports an unsatisfactory condition, damaged component, access problem or incomplete scope, record the issue and who is responsible for follow-up. A completed pump-out should not make an unresolved equipment problem disappear from the maintenance list.
Review the interval when the kitchen changes
Service timing should not be treated as permanent. Columbus’ current grease-interceptor design rules require review when new equipment is added, equipment capacity increases or a menu change increases grease production. For routine maintenance, the same idea is useful even when no construction project is involved: changes in production can make an old interval a poor fit.
Use the 25% rule guide and cleaning-frequency guide to separate actual accumulation from generic calendar advice.

Commercial Kitchen Grease Trap Maintenance Checklist FAQs
This checklist is not an instruction to enter a tank or perform unsafe technical work. Limit routine observations to what staff can safely review and leave confined-space or technical inspection work to qualified professionals.
Assign a responsible facility contact. A contractor may provide or complete service information, but the facility should verify that the required records are retained and tied to the correct equipment.
Do not assume increasingly frequent pumping is the only answer. Compare grease production, equipment condition, kitchen changes, service scope and any drainage problems with a qualified provider or professional.
No. It is a practical maintenance aid. Use the City’s official BMP materials for the facility plan and records required under the Columbus FOG program.
Turn the checklist into a documented service plan
Keep the equipment record, latest cleaning log and access notes together, then use them when requesting the next visit. That makes the conversation more specific and reduces the chance of booking the wrong scope.
