Yes, you should turn off sprinklers during a freeze to prevent water from freezing within the system, which could cause pipes to burst. Before the freeze hits, shut off the water supply to the sprinkler system and manually drain all the pipes. If your system is equipped with an automatic drain system, activation might occur when the system is depressurized. Consider insulating any above-ground components to provide extra protection against freezing temperatures. This preventative measure will save you from potentially costly repairs.
