Fuel oil storage and day tank maintenance checklists for the quarterly and annual rounds: 2 free lists, 12 items and 18 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against NFPA 110; the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule
- Fuel oil storage and day tank quarterly maintenance checklistquarterly
- Every quarter alongside the generator exercise, because a starved or waterlogged day tank only shows up when the set is loaded. Run by: The generator service tech or building maintenance mechanic, usually on the same visit as the standby generator round.
- Fuel oil storage and day tank annual maintenance checklistannual
- Once a year with the generator's annual service, when the set can be run under load long enough to prove the fuel path holds up. Run by: The fuel or generator service contractor on the annual standby service, coordinated with a scheduled generator load run.
What most often fails on a fuel oil storage and day tank
- Main tank gauge read as full while water has settled to the bottom and is feeding into the suction.
- Day tank float switch stuck, so the transfer pump either runs dry or overflows the return with no one watching the level.
- Weep at a flare fitting or filter head wiped up on the last visit and never traced, so it soaks the containment between rounds.
- Fuel polishing skipped because the tank 'looks clean' from the fill, while the bottom is carrying water and microbial growth that plugs filters under load.
- Vent line or its screen partially blocked, so the tank pulls a vacuum on draw-down and the day tank starves during the run.
- Filters changed but the change interval never adjusted after a heavy water bottom, so the next set plugs early.

Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
Common questions
- Which fuel oil storage and day tank maintenance rounds do these checklists cover?
- Fuel oil storage and day tank quarterly maintenance checklist (quarterly): Every quarter alongside the generator exercise, because a starved or waterlogged day tank only shows up when the set is loaded. Fuel oil storage and day tank annual maintenance checklist (annual): Once a year with the generator's annual service, when the set can be run under load long enough to prove the fuel path holds up.
- Who runs the fuel oil storage and day tank maintenance round?
- The generator service tech or building maintenance mechanic, usually on the same visit as the standby generator round. The fuel or generator service contractor on the annual standby service, coordinated with a scheduled generator load run.

- Which standards is fuel oil storage and day tank work verified against?
- NFPA 110, published by the National Fire Protection Association. Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 2 lists (12 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.
