Providing up to 2 hours of watering, this irrigation innovation connects directly to your tap and automatically shuts off the hose when the preset time runs out. No more remembering to turn off the tap, no more worrying about over watering — simply turn the dial to set the time and go! Keep your lawn lush, green, clean and beautiful with a perfectly timed watering schedule.
