Yard Mastery has contracted with a third party (SYSTEMS Environmental Products) to produce the 4-Gallon Backpack sprayers.
SYSTEMS Environmental Products ensures a 1-year parts & labor warranty outside of normal wear and tear. All warranty claims will be assessed on a case by case basis.
To maintain your sprayer, always use proper cleaning and storage procedures for the unit, including the battery and charger. This will ensure that your sprayer should last for many seasons to come.
If you need spare parts or an extra battery, here is a link to the page where you can purchase those.
