Sprinkler Mains and Hydrant Mains

Fire Hydrant systems are generally connected to town’s water main providing a means to deliver water to the Fire Service on large sites and within buildings to permit manual firefighting and rescue activities.

Fire Sprinkler systems are an automatic fire suppression system within a building which will activate once a sufficient heat source is detected spraying water to extinguish the fire. Sprinkler systems are usually charged with pressure from a pump with is fed from a water storage tank.
