Grease interceptor maintenance checklists for the quarterly and annual rounds: 2 free lists, 10 items and 14 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against IPC / UPC plumbing codes; the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule
- Grease interceptor quarterly maintenance checklistquarterly
- Every quarter, tightened to monthly for a busy kitchen — the depth reading is what sets the real pump-out interval, not the calendar alone. Run by: The kitchen facilities or plumbing tech on the quarterly round, or the grease hauler at a scheduled service.
- Grease interceptor annual maintenance checklistannual
- Once a year at minimum, done as a complete pump-out so the interior baffles and walls can be seen empty rather than through a floating grease layer. Run by: The licensed grease hauler with the facilities or plumbing tech present for the interior inspection.
What most often fails on a grease interceptor
- Depth never measured, so the interceptor fills past its capacity and grease carries straight through to the sewer between pump-outs.
- Pump-out manifests missing or unsigned, so there's no proof the hauler actually emptied it and the sewer authority has nothing to see.
- Lid gasket dried out and leaking odor into the kitchen, masked with deodorizer instead of being reseated.
- Interceptor 'pumped' by skimming the top grease while the hardened solids on the bottom are left, so the working capacity keeps shrinking.
- Cracked baffle or corroded outlet tee only visible with the tank empty, missed on every quarterly done through the access lid.
- In-ground tank taking in groundwater or losing its seal, diluting the sample and hiding how loaded it really is.
Verified against
Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
