16 views

You should winterize your sprinkler system when the temperature starts to consistently approach 32 degrees Fahrenheit (0 degrees Celsius). This is the freezing point of water, and ensuring your system is winterized before reaching these temperatures will prevent the water inside from freezing, expanding, and potentially causing damage to pipes and sprinkler components. It's best to schedule this maintenance in the fall, before the first freeze, to protect your system through the winter months.
