IrrigationPregunta 18 de 100
Misting or fogging from spray heads is usually a sign of what condition?
a.Pressure too low
b.Clogged emitters
c.Pressure too high
d.Broken lateral line
Explicación
When operating pressure is too high, the water leaves the nozzle atomized into a fine mist that drifts and evaporates instead of landing on the target area. The fix is to install pressure regulation so heads run at their rated pressure. Low pressure causes the opposite problem, poor throw and doughnut patterns.
