Simply attach four garden hoses (sold separately) to the Automatic Yard Watering System and set the timer to turn the water on as often and for the duration of time you designate. The timer requires three AA batteries, sold separately.# Digital 4-station timer # 2 automatic, leak-free valves # 4-outlet brass manifold # Instructions # Mounting hardware.The Automatic Yard Watering System connects to a standard faucet, providing four hose outlets, each with independent controls for convenient, remote operation.
