What is a precaution regarding the tank of a backpack sprayer?

• A. The top of the tank is often not water tight
• B. The tank should be emptied before use
• C. The tank must be full at all times
• D. The tank should be stored inverted

Answer: (A)

Backpack sprayer tanks often have a fill cap with a gasket that doesn’t form a perfect seal, so the top isn’t reliably watertight. Because the system is pressurized during pumping, even a small flaw in the cap or its gasket can let liquid escape from the top. The precaution is to inspect and replace worn gaskets, and to ensure the cap is fully tightened before use. Test for leaks around the fill area after sealing, and relieve pressure before opening the tank. Store and transport with the cap closed and the tank upright to minimize spills.
