Start saving water and money today. One of the biggest mysteries of a sprinkler system is how run your system so you don't waste water. Making sure you water the right amount leads to maximum sprinkler efficiency and that's where Orbit sprinkler catch cups come in. They simply and effectively help you conserve water, perform your own sprinkler audit and reduce your water bill by accurately measuring sprinkler application rates for each watering station. All you need to do is place the catch cups in the included catch stands, run your sprinklers for 10-20 minutes per zone, record the amount of water that falls into each cup and input the numbers into Orbit's exclusive watering schedule application. The application will tell you your irrigation efficiency and give you a timer schedule for each sprinkler zone, including correct length and frequency of watering for every month of the year.
