Chapin 4-Gallon 20V wide Mouth Backpack Sprayer Powered by Black & Decker - 6398
Mar 30, 2018
I own 5 of these for professional uses.
This is by far the best sprayer money can buy!!!! I use these for fence staining with oil based stain. (Not thick paint like stain though) We also use one for soapy water and 1 for bleach too.
The battery will spray non stop for way more than the listed 2 hours. Why would anyone want to pump their arm all day unless your just spot spraying. We put like 30 - 50 gallons through these things in just 1 day on 1 battery.
For bleach you must remove the metal screen inside the tank by pulling a small tab otherwise it will corrode and clog the pump. Which I easily fixed.
CONS
- Hose could be 2 feet longer
- I think one of them leaks a little at the top shoulder straps.
- The hose attached to the pump sometimes twists and I worry someday it may leak.
Installed these on an Isuzu NPR. Poor quality design.
1. The 2 rear hub parts were stuck together I had to hammer and use crow bars to separate them for about 30 minutes.
2. The "screws" that attach to the lugs are really soft metal. 3 of them stripped when tightening them on so I hope they don't fall off.
3. The Lug nut caps are barely holding on.
I miss the older design where you had to remove 3 lug nuts to install. They were much stronger but I can't seem to find the older design anymore.
