Dry-pipe sprinkler valve quarterly maintenance checklist
A quarterly dry-pipe valve round is short on purpose: it catches the wear items that fail between annual services. This checklist is sized for a tech with a phone. Every item says what to look at and the photo that proves the round happened. Work is commonly verified against NFPA 25, NFPA 13. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The building engineer or sprinkler service tech reading the gauges and the enclosure on the quarterly round, recording conditions rather than tripping the valve.
When in the schedule
Every quarter, and watched most closely heading into cold weather since the enclosure heat is what keeps the valve from freezing and false-tripping.
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.
Pressures and priming
- 2 photos
Air and water pressures read and the differential compared
System air pressure and supply water pressure both read at the gauges and compared against the valve's required differential, readings noted, neither gauge stuck or pinned.
- 1 photo
Priming water level checked at the priming valve
Priming level checked at the test/priming valve, water present to the intended level over the clapper, no excess backing over the seat.
Alarms and quick-opening device
- 1 photo
Low-air alarm and its pressure setting observed
Low-air supervisory setting on the switch or maintenance-air device read against the intended value, the low-air signal confirmed reaching the panel where it can be observed without tripping the valve.
- 1 photo
Quick-opening device condition observed where fitted
Accelerator or exhauster isolating valve open, device pressurized and free of leaks, priming chamber where fitted not weeping, nothing left isolated after prior work.
Enclosure and valve
- 2 photos
Enclosure heat and freeze protection observed
Valve enclosure or riser room held above freezing, heater or heat trace operating, thermostat set and the space free of drafts at the openings.
- 1 photo
Valve position and supervision checked
Main control valve open and supervised, tamper confirmed reporting to the panel, trim valves in their normal positions and the reset/trip instruction plate legible.
What usually sends this back
The failures are almost always the evidence, not the work
- System air and water gauges read individually but never compared, so a differential that has crept toward the trip point isn't caught before the valve dumps on its own.
- The enclosure heater tripped or the space cold, discovered only after ice at the clapper false-trips the valve and floods the system.
- Priming water level never checked, so water backs over the clapper seat and the valve either weeps through or trips low.
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 8 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 dry-pipe sprinkler valve quarterly checklist cover?
- 6 items across 3 sections, covering pressures and priming, alarms and quick-opening device, enclosure and valve. 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 building engineer or sprinkler service tech reading the gauges and the enclosure on the quarterly round, recording conditions rather than tripping the valve.
- When in the schedule should this walk happen?
- Every quarter, and watched most closely heading into cold weather since the enclosure heat is what keeps the valve from freezing and false-tripping.
- Why does every item ask for a photo?
- 8 of the 6 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 dry-pipe sprinkler valve quarterly inspection?
- System air and water gauges read individually but never compared, so a differential that has crept toward the trip point isn't caught before the valve dumps on its own. The enclosure heater tripped or the space cold, discovered only after ice at the clapper false-trips the valve and floods the system. Priming water level never checked, so water backs over the clapper seat and the valve either weeps through or trips low.
- 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.
