If nozzles clog repeatedly, which component is most likely not working properly?

• A. The agitator is not working properly
• B. The pump is clogged
• C. The nozzle screens are blocked
• D. The pressure gauge is faulty

Answer: (A)

Repeated nozzle clogging usually means the spray mix isn’t staying properly mixed. The agitator’s job is to keep the formulation in suspension so solids don’t settle out. When the agitator isn’t working, solids fall to the bottom and can accumulate and travel to the nozzle area, clogging the screens or passages each time you spray. That’s why the agitator failing is the most likely cause.

A pump being clogged would slow or stop flow but doesn’t inherently explain why clogging happens again and again at the nozzles. A blocked nozzle screen is a symptom you’d see if debris reached the nozzle, but it wouldn’t by itself cause the repeated clogging unless the material is not being kept in suspension. A faulty pressure gauge would affect readings, not the physical clogging of nozzles.
