Sewage grinder pump quarterly maintenance checklist
A quarterly sewage grinder pump 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 the applicable plumbing code, manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The plumbing or maintenance tech running the station through a cycle on the quarterly round, watching it start, grind, pump down and stop, and checking the alarm.
When in the schedule
Every quarter, since a grinder pump lives in a sealed basin nobody opens until it alarms, and by then a jammed cutter or a stuck float is already backing sewage up.
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.
Pump cycle and cutters
- 2 photos
Station runs a full pump-down cycle
Pump seen starting on level, grinding and pumping the basin down to its stop point and shutting off cleanly, no long run suggesting a worn cutter or a fouled impeller.
- 1 photo
Run current and cutter condition observed
Running amps consistent with the pump's normal draw, no grinding or cavitation noise, no sign the cutter is dragging or the motor is laboring against a jam.
Level controls and check valve
- 1 photo
Level controls start and stop the pump at the right points
Floats or level sensor free of grease and rag, the pump seen starting and stopping at its set levels, off-level not so low it lets the pump run dry.
- 1 photo
Check valve holds after pump-down
Discharge check valve seen holding after the pump stops, level not creeping back up from drain-back, no water hammer as the valve seats.
Alarm
- 1 photo
High-level alarm tests good
High-level float or sensor lifted or simulated and the audible and visual alarm confirmed operating, any remote or panel signal seen reporting.
What usually sends this back
The failures are almost always the evidence, not the work
- Floats or the level sensor fouled with grease and rag, so the pump either short-cycles or never starts and the basin creeps toward overflow.
- Check valve stuck open or fouled, so each pump-down drains back into the basin and the pump runs far more than it should.
- High-level alarm float or the alarm itself dead, so the one warning the station gives before it overflows never sounds.
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 6 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 sewage grinder pump quarterly checklist cover?
- 5 items across 3 sections, covering pump cycle and cutters, level controls and check valve, alarm. 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 plumbing or maintenance tech running the station through a cycle on the quarterly round, watching it start, grind, pump down and stop, and checking the alarm.
- When in the schedule should this walk happen?
- Every quarter, since a grinder pump lives in a sealed basin nobody opens until it alarms, and by then a jammed cutter or a stuck float is already backing sewage up.
- Why does every item ask for a photo?
- 6 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 sewage grinder pump quarterly inspection?
- Floats or the level sensor fouled with grease and rag, so the pump either short-cycles or never starts and the basin creeps toward overflow. Check valve stuck open or fouled, so each pump-down drains back into the basin and the pump runs far more than it should. High-level alarm float or the alarm itself dead, so the one warning the station gives before it overflows never sounds.
- 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.
