If sprayer pressure is too low, what is the most likely cause?

• A. The nozzles have become worn
• B. The pump is failing
• C. The tank is low on solution
• D. The filter is clogged

Answer: (A)

When spray pressure is too low, the most likely culprit is nozzle wear because worn nozzles enlarge the exit opening and reduce the system’s backpressure. With larger passages, the pump has to push more liquid through a less restricted nozzle at the same pressure setting, and if the pump can’t maintain that demand, the measured pressure drops. Replacing the worn nozzles restores the proper restriction, letting the pump build and hold the correct pressure. A failing pump would typically show a more direct, overall loss of pressure or erratic readings; a tank that's low on solution mainly reduces total volume rather than the pressure in the lines; a clogged filter can reduce flow and may lower pressure in some cases, but the most common fix when pressure is visibly low is worn nozzles.
