    Chapin 20v Backpack sprayers

    By Tom on 04/12/2020

    The sprayers are poorly designed you might get eight months to a year out of them and then either the switch to turn them on goes bad or there's no pressure. I have purchased 4 of these sprayers in the last 2 years

    LCN approved!

    By Eric on 05/04/2018

    LCN approved, works exactly as expected. Sprayed twice with it and love it. Cant wait to try out more concentrated liquid products on the lawn. No leaks, quality product, sturdy, nice grip/wand. I highly recommend.

    so far, so good

    By Rob on 05/25/2018

    Very happy with performance after using sprayer on 2 different occasions. Maybe I'm lazy but I like the fact that spray has same power output because of battery versus pump that slows down as pressure fades. Also backpack capacity over my 1 gal sprayer better for almost half acre property

    Backpack Sprayer 63985

    By Gary on 05/22/2020

    Purchased for home use in Texas Hill Country 1.5 acres. After charging battery, my 1st run was with 4 gallons, my 2nd was another 4GL and my last was 3GL. The sprayer and battery worked perfectly. Excellent product!

    Working great for almost 3 years now

    By Bob on 01/25/2021

    Verified Purchase

    I bought this on a recommendation from The Lawn Care Nut. I love this sprayer. I use it for blanket apps of liquid fertilizer, herbicide and pesticide on the lawn as well as treating the perimeter of the house with pesticide. I have had it for almost 3 years and it is still running great.

Q
Once I turn my Chapin 4 Gallon 20v Wide Mouth Backpack Sprayer on, it never stops running/priming. Seems to spray fine, just never stops running until I switch.
A

We are sorry that you are having trouble with your Chapin 4 Gallon 20v Wide Mouth Backpack Sprayer! You should hear the battery running while the unit is turned on, but you should be able to control the spray using the handle to stop and start the flow of liquid from the handle. If something is getting caught in the handle, then you may need to give Chapin a call directly to troubleshoot this issue. You can reach them directly at 800-950-4458. Please let us know if you have any trouble contacting them or need further assistance.

Q
Will a Milwaukee 20 V battery work on the Chapin 4 Gallon 20v Wide Mouth Backpack Sprayer 63985?
A

The Chapin 4 Gallon 20v Wide Mouth Backpack Sprayer 63985 should use the lithium battery suggested by Chapin. The 20V replacement battery is to be used in the Chapin Backpack Sprayer 4 Gal. 20V Lithium Black & Decker Battery (63980) also.

Q
Is there a metal wand available for the Chapin 4 Gallon 20V Wide Mouth Backpack Sprayer 63985?

In the summer sun the plastic wand curls into a "C" shape.

A

The only replacement wand for the Chapin 4 Gallon Backpack Sprayer 63985 is the plastic wand, part 6-8219. Be sure you are storing your sprayer empty, clean, and out of direct sunlight and extreme heat to prevent damage. We have other backpack sprayers like the Chapin 62000 that do have metal wands, if needed.
