What is a Sprinkler System Comprised Of?

An automatic sprinkler system is made of 3 main components: a controller, valves and sprinklers.
The Controller is the system’s brain
When the Controller reaches a programmed start time, it sends a signal to one of the valves telling it to open. Each valve controls a group of sprinklers. Each group of sprinklers is called a zone or station.
The valve works like an automatic faucet. When it receives the commend from the controller it opens the flow of water
When the run time for the zone is done the controller tells the valve to close. The valve closes, shutting off the flow of water to the sprinklers.
The process is repeated for each group of sprinklers in the system.
