Maintenance Procedure For Fire Sprinkler, Stand Pipe, Hydrant & Hose Reel Systems

Maintenance Instructions for the maintenance of Fire Sprinkler, Stand Pipe, Hydrant & Hose Reel Systems including fire fighting pump sets.

  1. Maintenance Of Sprinkler System: Installation of Control Valve (Alarm Valve)

It is recommended that the Alarm Valve be inspected periodically to ensure proper operation.  Several areas to be routinely inspected are:


Clapper/Clapper Latch: The rubber clapper facing should be checked for wear or damage and to determine it is free of dirt and other foreign substances. If found to be worn or damaged (eg. foreign matter embedded in the surface ) the facing should be replaced. If it is dirty, it should be cleaned, but compounds, which could damage the rubber facing, should never be used.

Seat Ring: The seat ring should be cleaned thoroughly and checked for damage.  If it is found to be damaged, the complete valve assembly should be replaced or returned to fire systems supplier for reconditioning.

By pass check valve. The ¾ “ check valve in the external by pass should be checked for clapper & seat condition.

Alarm Line Strainer.  The strainers in the alarm line, pilot line and air supply should be checked and cleaned thoroughly.

Alarm Test Valve & Main Drain Valve.  All controlling valves normally closed when the Alarm valve is in the set position should be checked to be sure that they are fully closed and not leaking.

Alarm Valve & Trim.  The overall setup should be checked for visible leaks and possible physical damage to the valve and connections (e.g., broken gages)
