Still working
By Ernie on 05/25/2024
My dad bought a 425 back in the late 80s. He bought 2. One for bugs and one for weeds. One finally conked out after he died. I am still using the other one. Just wanted to make a testament to a product that was made to last. After about 40 years, it is still working fine. THANKS SOLO.
I'm looking fit a good sprayer to apply bleach to roofs affected by algae and moss would this be a good sprayer to use? If not could you recommend one? Thanks
It would not be recommended to use bleach in the Solo 425 4-Gallon Professional Piston Backpack Sprayer. Instead you could use the Chapin Euro Bleach Backpack Sprayer 4 Gal. (61575) or Chapin Industrial Poly Bleach Sprayer 1 Gal. (20075) designed to hold up against this harsh chemical.

No, the Solo 425 4 Gallon Professional Backpack Sprayer is a pump sprayer. If you are looking for a battery-powered sprayer, you may want to consider the Solo 416 Battery Backpack Sprayer.
