Irrigation Heads Spraying Unevenly — San Francisco, California
Sprinkler heads that spit, mist weakly on one side, or leave dry patches in an otherwise green zone indicate clogged nozzles, incorrect head pressure, or worn internal seals. When pop-up bodies are cracked or tilted by settling soil, the spray arc shifts and coverage suffers. Low-pressure misting wastes water through evaporation while failing to wet root zones. A landscaper or irrigation technician can flush the line, replace clogged or worn nozzles, adjust arc and radius settings, swap damaged risers, and verify zone pressure is within the head manufacturer's rated range so each head delivers its designed pattern.
