A lift station is unattended infrastructure whose failure mode is a sanitary sewer overflow — raw sewage into a street or watercourse, which is a public health event and a reportable regulatory one. Duty pumps bind with rags and wipes, seals admit water into the oil chamber, and float switches stick. The redundancy that protects the station is a second pump and a working alarm, so verifying both is the job.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

Stations run on one pump for weeks without anyone knowing, because the duty pump covers normal flow and nothing reports the standby's failure. Then a storm arrives, the single working pump cannot keep up, and the overflow happens at the worst possible moment. The untested alarm dialler is the compounding failure: the operator finds out from a member of the public.
Quarterly service with the run-hour leg leading on high-flow stations. Compare pump run times between duty and standby at every visit — divergence is the cheapest early indicator of a binding or failing unit, and it costs nothing to read.
