- Follow these steps to prevent freezing components of your sprinkler system. Operating your system in the winter is risky and will likely damage your system requiring spring repair.
- Remember to detach all hoses from any faucets outside your home to prevent damage.
- Remember to winter water by hand. Colorado’s dry winter climate can leave your grass, trees and plants susceptible to desiccation, and in need of water.
- Remember to check the 9V battery in your sprinkler clock to assure the programming is maintained in the case of a power outage.
