What does this wet sprinkler riser annual checklist cover?

13 items across 5 sections, covering notice and impairment, main drain test, valves and trim, alarm verification, and more. 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 sprinkler service tech running the annual inspection, results recorded on the inspection report rather than a certification.

When in the schedule should this walk happen?

Once a year, with water available for a full main-drain test and coordinated so the alarm test doesn't dispatch the monitoring station unannounced.

Why do these items ask for a photo?

7 of the 13 items call for photo evidence, 10 photos in all. 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 wet sprinkler riser annual inspection?

Main-drain test run but the static and residual pressures never recorded against last year's, so a gradual supply obstruction trends invisibly. Control valve exercised open-to-shut on paper but never walked fully closed and back, so a seized valve isn't found until it's needed. Alarm test called in to the monitoring station but the actual signal receipt never confirmed back, so a broken communicator passes.

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.

Wet sprinkler riser annual maintenance checklist

The annual sprinkler riser 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 NFPA 25, NFPA 13. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

Notice and impairment

Monitoring company and owner notified before the annual tests
Monitoring company told alarm and supervisory signals are coming, the owner notified of the test window, and the call logged before work starts.
No photo
Impairment procedure followed while valves are exercised
Impairment logged under the owner's procedure before any control valve is closed, affected floors known, and a fire watch arranged where required.
No photo

Main drain test

Full main-drain test performed with pressures recorded
Static pressure read, main drain fully opened, residual pressure recorded and compared against prior years to catch a supply obstruction.
Gauges checked for accuracy
Gauge readings cross-checked against a calibrated test gauge, any sticking or off-reading gauge flagged for replacement.

Valves and trim

Control valve fully operated through its travel
Valve walked fully closed and back open, operates without binding, left open and re-secured with the tamper confirmed.
Riser trim, check valve and priming observed
Alarm check valve trim and drains clear, no weeping at the clapper, retard chamber draining, no corrosion at the trim piping.
No photo
Tamper switch trip point checked early in valve travel
Supervisory signal given early in the closing travel, as the switch manufacturer sets it, and not only once the valve is fully shut.

Alarm verification

Alarm and supervisory signals tested and receipt confirmed
Waterflow and valve-supervisory signals tested through to the panel and the monitoring station, receipt confirmed back before reset.
Waterflow signal delay checked against the device setting
Time from test flow to panel signal matches the retard or flow switch delay setting, with no false trip from a pressure surge.
No photo

Spares and return to service

Spare sprinkler cabinet stocked for each installed type
Spares match each head type and temperature rating installed, a wrench for each type is present, and the posted list of installed heads is current.
All riser valves back in normal position after testing
Main drain and test valves shut, every control valve walked open and sealed, and the panel normal with no alarm or supervisory standing.
Monitoring company and owner told the riser is back in service
Monitoring company confirms the account is back on normal monitoring, the owner is told, and the impairment is closed in the owner's log.
No photo
Inspection report left with the owner
Report records the main drain readings, the valve, alarm and spares results, and each deficiency found, filed with the owner for their records.
No photo

What usually sends this back

The failures are almost always the evidence, not the work

Main-drain test run but the static and residual pressures never recorded against last year's, so a gradual supply obstruction trends invisibly.
Control valve exercised open-to-shut on paper but never walked fully closed and back, so a seized valve isn't found until it's needed.
Alarm test called in to the monitoring station but the actual signal receipt never confirmed back, so a broken communicator passes.
