Stop wasting water， chemical concentrate and time with Mixes on Exit™， the clean tank spraying system from Chapin. Separate water and concentrate tanks mean no more messy and wasteful premixing of chemicals - and your water stays clean! The Mixes on Exit system is designed around 2 tanks - a 15 gallon water tank and a 1.33 gallon concentrate tank - and a 2.5 GPM pump that connects to your ATV/UTV/Lawn Tractor battery. The included lockable poly shut-off and wand provide versatile， adjustable spraying on the go， with optional boom spray kits available (sold separately). A simple Mix Valve control allows you to adjust the concentrate from 1 to 15 ounces per gallon. One year limited warranty.
