Chapin Professional 4-Gallon Backpack Sprayer
$68
This is the sprayer I reach for on bigger jobs. Four gallons is the right capacity — enough to do a complete residential perimeter treatment in one load. The pump action is smooth, the wand gives you good control, and it doesn't leak if you maintain the seals. Maintain the seals.
Specs
- 4-gallon capacity
- Padded backpack harness
- Brass wand with adjustable nozzle
- Translucent tank with measurement markings
Dave's Take
“I've used a lot of sprayers. This one doesn't embarrass me. Buy it, clean it after every use, and replace the gaskets before they fail rather than after. You'll know when they're starting to go.”
