Domestic water heater maintenance checklists for the quarterly and annual rounds: 2 free lists, 28 items and 22 photo requirements, each item naming what to look for and the photo evidence it needs.

What most often fails on a domestic water heater
- T&P valve assumed good because it isn't dripping. It's never actually lifted and reseated.
- Flue or intake partially blocked by stored material in the mechanical room.
- Delivered temperature drifting high or low with no one reading a fixture, just the aquastat.
- Tank 'flushed' until the first cup runs clear while pounds of sediment stay behind.
- Anode never pulled because the ceiling clearance makes it awkward, so the tank fails early instead.
Verified against
Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
