    back pack sprayer

    By Scott on 08/30/2019

    The sprayer works great except for the top leaks around the cap...it appears the top is not perfectly round and the cap gasket must not make a good seal

    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.

Q
Will this Solo 425 hold up against bleach?

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

A

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.
