Keep up to two areas of the yard regularly watered with the Melnor 2-Zone Digital Water Timer. Each zone works like a separate timer, so the squash and daisies can be watered every morning while the lawn sprinkler comes on every few days. The dirt-resistant valve keeps water flowing smoothly through the timer, even with girt commonly found in well water, ensuring reliable operation year after year. Turn on the ECO mode to allow water to soak into the soil and prevent run-off. Avoid wasting water when it rains with the handy rain delay to pause the watering schedule. Need to wash the car or spray off the walkway. Manual mode allows you to turn on the water whenever you need it.
