Where each walk sits in the schedule
01quarterly
Sewage grinder pump quarterly maintenance checklist
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.
Run by: 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.
02annual
Sewage grinder pump annual maintenance checklist
Once a year, the pass that pulls the pump to look at the cutter, impeller and seals, which the quarterly cycle-and-listen check can't see inside a sealed basin.
Run by: The pump service tech on the annual service, pulling and inspecting the pump, cleaning the basin and floats, and rechecking the full cycle.
What most often fails on a sewage grinder pump
- 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.
- Basin pumped down but never cleaned, so grease and grit build back onto the floats within weeks and the short-cycling returns.
- Cutter and impeller wear noted but not measured against the manufacturer's limits, so a pump grinding to failure is signed off as serviceable.

- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 2 lists (30 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper evident audit trail.
Run these lists with the Photo Gate.
Tag one area, scan it, and the submit stays locked until the photos exist.
