Do you know what your sprinkler system does in the dark? Many of us – rightly – set our sprinkler systems to go off during the night or early morning hours. This reduces evaporative losses compared to mid-day watering. However, if your sprinkler system develops problems such as broken sprinkler heads, you might not see the water waste because you are tucked in your bed. Periodically, turn on your sprinklers during daylight hours to inspect the system for broken, clogged or misaligned heads.
