You can li save thousands of gallons of water in your landscape, and save your plants from drowning, with the proper setting of your irrigation controller. But you can’t just set it and forget it. You need to change the watering schedules as plants become established, with the changing seasons and when it rains. Here’s an easy guide to make setting your irrigation controller easier than programming.
Many people don’t know that when the power goes out, many irrigation timers revert to the “default” setting, which usually turns on the sprinklers for 10 minutes a day, seven times a week. This can not only cause you to have a very wet yard, but can result in higher water bills and urban runoff.
A. Be sure your controller has a back-up battery in case of a power outage and replace it every time you replace your fire alarm batteries. Most controllers take a 9 volt battery, which is located behind or under the controller face.
B. Check your controller’s run times; if they’re set to water seven days a week, 10 minutes for each zone this means you have experienced a power outage and your controller’s back-up battery is dead or missing.
C. Now it’s time to re-schedule your run times.
