What are the consequences of ignoring clogged nozzles and sprinkler heads in my lawn irrigation system?

Ignoring clogged nozzles and sprinkler heads can lead to uneven water distribution, reduced water pressure, and decreased system performance. This can result in overwatering or underwatering of certain areas, leading to plant stress, disease, and pest issues. Additionally, clogged nozzles and sprinkler heads can increase water waste and energy consumption, leading to higher utility bills.
