Weekly Dry Sprinkler Valve Maintenance Checklist
by Daniel Van Oosten, from the Community
This weekly preventive maintenance checklist covers the Viking Model G-4000 dry fire sprinkler valve. It guides technicians through tools and safety prep, coordination with site personnel, and step-by-step checks: verify supply and system pressure ratios, confirm the dry valve’s intermediate chamber is free of water via the drip check, check for air at the PORV outlet, inspect accelerator pressures if fitted, and ensure the water supply control and trim valves are in normal operating positions. Inspect for mechanical damage or corrosion, confirm adequate heating and freeze protection, verify proper signal at the fire alarm control panel, and record findings in the equipment history log.
