When should you winterize your lawn sprinkler system in Maryland, and what can happen if you wait too long? In this video, TLC Incorporated explains why fall irrigation winterization matters and how proper sprinkler blowout and system preparation can help protect your irrigation system from freezing temperatures.

TLC recommends winterizing irrigation systems before the season's first freeze, typically in late fall. Proper winterization involves shutting off the water supply, removing excess water from the irrigation lines, inspecting system components, and adjusting controls so the system doesn't accidentally run during the winter. These steps can help protect pipes, sprinkler heads, and other components from freezing damage and help make spring startup easier.
