Yes, sprinkler heads can freeze if water remains in them during cold weather, leading to potential damage. It's important to winterize your sprinkler system by draining water from the pipes, valves, and sprinkler heads before the first freeze. This can be done manually, or by using an air compressor to blow out the remaining water. Always make sure to shut off the water supply to the sprinkler system and remove any above-ground hoses to prevent freezing and cracking during the winter months.
