Chapin combined so many features into our 63900 self-cleaning backpack sprayer. Whether you're a DIYer or a professional this sprayer tackles jobs with ease. It offers an innovative and patented JetClean, self-cleaning pump technology, directing a powerful burst of liquid through the tank filter with each downward pump stroke. The filter stays free of debris and virtually eliminates clogging! The benefits continue with a 4-Gallon (15-liter) translucent poly tank with an extra-wide mouth opening for easy filling and cleaning, a 3-stage filtration system, cushion grip poly shut-off, 3 nozzles for a variety of applications and a stainless-steel wand. The swing-away pump handle can be set up for either right or left-hand use and it folds up when you're done. Compatible with common fertilizers, weed killers and pesticides.
