# Step-by-Step on How to Replace a Solenoid Valve on a Sprinkler System
Automatic sprinkling systems utilize solenoid-operated valves to disburse water in selected areas known as zones. A solenoid device converts electricity to mechanical action. A preset timer sends an electrical current to the zone solenoid, which opens the sprinkler water valve. When the timer signals the solenoid circuit, the water valve closes and the sprinkler is turned off. You can replace a faulty solenoid on a sprinkler system valve in 10 minutes or less.
