The Wet Alarm Check Valve (150mm Flanged) is a critical component of wet pipe sprinkler systems. It prevents reverse water flow while providing hydraulic signals to alarm devices when water flows in the system.
For optimal safety, commercial extinguishers should be inspected monthly and professionally serviced annually as per strict fire safety standards.
Most dry chemical extinguishers last between 10-12 years if maintained correctly, but the propellant and cylinder integrity must be checked regularly.
