Does the knapsack sprayer you are considering to buy – leak?
Leaks are regarded by many as the most important problem of knapsack sprayers today. Tank lids, shut-off valves, hoses and their attachment points must all be effective at controlling leaks; under pressure and when the sprayer is vertical, inclined and even horizontal.
Will the sprayer be safe and comfortable to use?
Knapsack Sprayer must be convenient to carry and comfortable to use. Check to establish it has a lifting point[s] and its fully loaded weight can be readily carried. Straps and their fixing points are critical. Wrong straps may break, come loose, be very uncomfortable and absorb spray solution. Does it also have a waist belt to both secure the sprayer in use and stabilise it when pumping?
Can the sprayer be filled without spillage yet remains capable of filtering out debris that can clog the spray line and nozzle?
Knapsack sprayers are normally filled with spray solutions prepared in buckets. They have to be filled quickly [typically within 60 seconds] without excessive splash or spill and with adequate filtration.
