During the design of a residential sprinkler system, domestic water use should be taken into consideration unless the domestic supply can be stopped when a sprinkler operates
When a sprinkler operates, water supply is automatically diverted from the domestic system to the sprinkler system
Eliminates the need for pumps, pressurized storage tanks, or electrically operated domestic shutoff valves
Valve automatically resets after the fire protection system is returned to normal service
