What should you always do before mixing in a backpack sprayer?

• A. Add water to the tank
• B. Add concentrate first
• C. Turn on the pump dry
• D. Remove all parts

Answer: (A)

Always fill the tank with water before adding any chemical concentrate. By starting with water, you provide a ready diluent so the concentrate can dissolve evenly as you add it, avoiding undissolved pockets that can cling to the bottom or leave concentrated areas in the mix. This also helps ensure you achieve the correct final spray volume and prevents running the pump dry, which can damage the sprayer. After adding water, add the concentrate and then mix thoroughly to reach a uniform solution. Remember to follow the label for the proper mixing order and wear the appropriate PPE.
