Automate your drip system and enjoy worry-free watering with the Hose-End Automatic Water Timer. The user-friendly timer makes it easy to program run time and frequency by using the two bottom dials, and the control dial on top enables timed manual watering and rain delay. Indicator lights blink when changes are made; the battery-operated timer also indicates when batteries are running low. System turns valve to the "off" position when batteries run out, to prevent wasting water. The Auto Timer also comes with a Smart Loc™ Universal Adapter which attaches to the bottom of the timer. This unique fitting accommodates tubing and dripline of multiple sizes, and the swivel prevents the tubing from kinking. Timer and adapter are made of acrylonitrile butadiene styrene (ABS).
