Oil-water separator maintenance checklists
Oil-water separator maintenance checklists for the quarterly and annual rounds: 2 free lists, 28 items and 17 photo requirements, each item naming what to look for and the photo evidence it needs. Work is commonly verified against IPC / UPC plumbing codes; the edition in force is the AHJ's call on each project.
The oil-water separator rounds
Where each walk sits in the schedule
01quarterly
Oil-water separator quarterly maintenance checklist
Every quarter, and sooner after a heavy spill or wash-down event that loads the separator faster than usual.
Run by: The plumbing or facilities tech on the quarterly round at the separator.
02annual
Oil-water separator annual maintenance checklist
Once a year, coordinated with the pump-out so the tank is drawn down and the media can actually be pulled and looked at.
Run by: The plumbing service tech with the licensed pump-out hauler on the annual visit.
What most often fails on an oil-water separator
- Oil layer let build past the point where it carries over to the outlet because nobody dipped the top layer, only glanced at the cover.
- Sludge on the bottom never measured, so the coalescing media chokes and short-circuits long before the next pump-out is scheduled.
- High-oil alarm assumed live because a light is on, never actually tripped by floating the sensor.
- Tank pumped but the coalescing media left in place year after year, blinded solid, so oil and water pass straight through no longer separating.
- Pump-out done without a hauler manifest kept, so there's no record of volume or disposal when it's asked for.
- Sample or inspection port left silted over and never cleared, so future quarterly checks can't actually see the effluent.

Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
