Grease interceptor quarterly maintenance checklist
A quarterly grease interceptor round is short on purpose: it catches the wear items that fail between annual services. This checklist is sized for a tech with a phone. Every item says what to look at and the photo that proves the round happened. Work is commonly verified against IPC / UPC plumbing codes, manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The kitchen facilities or plumbing tech on the quarterly round, or the grease hauler at a scheduled service.
When in the schedule
Every quarter, tightened to monthly for a busy kitchen — the depth reading is what sets the real pump-out interval, not the calendar alone.
The checklist
Every item, and the photo that proves it
The photo count on each row is what RTI would require before the item can be submitted. Copy the list as is, or load it into RTI and let the gate enforce it.
Capacity and cleaning
- 2 photos
Grease cap and solids depth measured
FOG layer on top and settled solids on the bottom measured with a dip stick, compared against the interceptor's capacity to trigger a pump-out.
- 1 photo
Pump-out record and hauler manifest reviewed
Last service date and volume logged, signed hauler manifest on file, interval adjusted to the measured loading.
Internals
- 2 photos
Baffles and inlet/outlet tees checked
Baffles and tees in place and intact, no grease shortcutting from inlet to outlet, outlet tee dipping below the grease layer.
- 1 photo
Flow-control fitting and vent verified
Flow-control device present and unobstructed so the unit isn't surged past its rating, air intake or vent clear.
Lid and odor
- 1 photo
Lid, frame and gasket inspected
Lid seats fully, gasket sound, bolts or clamps secure, no seepage or odor escaping around the cover.
What usually sends this back
The failures are almost always the evidence, not the work
- 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.
Run it with the Photo Gate
A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 7 required photos exist. Approved walks roll into a branded turnover package with a tamper-evident record behind every line.
Submission state
The gate is enforced on the server, so it holds even if the phone is offline when the walk happens.

Common questions
- What does this grease interceptor quarterly checklist cover?
- 5 items across 3 sections, covering capacity and cleaning, internals, lid and odor. Each item spells out what the person walking the job is actually looking for, not just a box to tick.
- Who should run this inspection?
- The kitchen facilities or plumbing tech on the quarterly round, or the grease hauler at a scheduled service.
- When in the schedule should this walk happen?
- Every quarter, tightened to monthly for a busy kitchen — the depth reading is what sets the real pump-out interval, not the calendar alone.
- Why does every item ask for a photo?
- 7 of the 5 items call for photo evidence. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.
- What most often fails a grease interceptor quarterly inspection?
- 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.
- Can I use this checklist in RTI?
- Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper-evident audit trail.
