Automatic Sprinkler Inspection, Testing & Maintenance

Alarm check valves

Alarm check valves must be cleaned and repaired as needed in accordance with the manufacturer's recommendations. During the internal inspection of an alarm check valve check the condition of the valve seat and the rubber gasket on the bottom of the flapper in the check valve. It is not uncommon for small pieces of debris to lodge on the machined valve seat and cause grooves or pitting. This can result in water leaking back through the check valve.
