Which issue is listed as a common equipment failure?

• A. Leaking spray tanks.
• B. Worn hoses.
• C. Worn gauges.
• D. Worn gaskets and seals.

Answer: (C)

Maintaining accurate spray results depends on knowing the actual pressure inside the system. The pressure gauge is the instrument that tells you that. When gauges wear, their readings drift and become unreliable. That means your spray can be delivered at the wrong rate, even if you set it correctly, leading to under- or over-application, uneven coverage, and potential drift in performance. Gauges tend to wear from constant vibration, exposure to chemicals, and age, making gauge wear a common and impactful equipment failure in spray systems.

Regular inspection and replacement of worn gauges are essential so you can verify true system pressure and keep calibration accurate. The other issues—leaking spray tanks, worn hoses, and worn gaskets/seals—are important problems, but gauge wear specifically undermines the ability to monitor and control application rates, which is why it’s the best answer.
