The Raindrip Dual Station Water Timer is a simple way to automatically water two separate garden areas from one water source. The frequency and duration can be individually programmed for each outlet from one hour to one week in intervals of one minute to two hours. Temporary override of settings is also possible for manual watering. Operating with a water pressure of 10 to 80 PSI, the Dual Station Water Timer requires a 9-volt battery (not included) and features a low-battery indicator to know when it’s time for a replacement. A 90-day limited warranty covers every new Dual Station Water Timer purchase.
