Domestic water heater annual maintenance checklist
The annual domestic water heater service is the deep pass — the measurements, cleanings and tests a quarterly round doesn't reach. This checklist keeps the full service on record with the photos that make it defensible later. Work is commonly verified against IPC / UPC plumbing codes — confirm the edition your authority having jurisdiction has adopted.

Who runs it
The plumbing service tech on the annual service visit.
When in the schedule
Once a year — the flush is what keeps sediment from cooking the bottom of the tank or coating the elements.
The checklist
Every item, and the photo that proves it
The photo count on each row is what RTI would require before the item can be submitted. Copy the list as-is, or load it into RTI and let the gate enforce it.
Flush and internals
- 2 photos
Tank flushed until discharge runs clear
Discharge observed running clear, sediment volume noted — heavy sediment changes the service interval.
- 1 photo
Anode rod or elements inspected where accessible
Anode consumption checked and logged, elements free of scale on electric units.
Safety and performance
- 1 photo
All safeties and shutoffs functionally tested
T&P re-tested after the flush, gas or power shutoff operated, mixing valve output verified.
- 1 photo
Recovery and capacity observed
Unit brought through a recovery cycle, no unusual noise, delay or short-cycling.
Housekeeping
- 1 photo
Mechanical area kept clear around the unit
Required clearances maintained, no storage against the vent or blocking the service side.
What usually sends this back
The failures are almost always the evidence, not the work
- Tank 'flushed' until the first cup runs clear while pounds of sediment stay behind.
- Anode never pulled because the ceiling clearance makes it awkward — the tank fails early instead.
Run it with the Photo Gate
A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 6 required photos exist. Approved walks roll into a branded turnover package with a tamper-evident record behind every line.
Submission state
The gate is enforced on the server, so it holds even if the phone is offline when the walk happens.
Common questions
- What does this domestic water heater annual checklist cover?
- 5 items across 3 sections — flush and internals, safety and performance, housekeeping. Each item spells out what the person walking the job is actually looking for, not just a box to tick.
- Who should run this inspection?
- The plumbing service tech on the annual service visit.
- When in the schedule should this walk happen?
- Once a year — the flush is what keeps sediment from cooking the bottom of the tank or coating the elements.
- Why does every item ask for a photo?
- 6 of the 5 items call for photo evidence. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.
- What most often fails a domestic water heater annual inspection?
- Tank 'flushed' until the first cup runs clear while pounds of sediment stay behind. Anode never pulled because the ceiling clearance makes it awkward — the tank fails early instead.
- Can I use this checklist in RTI?
- Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper-evident audit trail.
