    Any idea what the pump pressure is on a solo backpack sprayer? I usually walk and constantly pump. Got a few laws that must be treated that way. What nozzles are you guys using in the back packs? Floodjets?

    Depends on how fast you pump. Why not install a pressure guage. or a pressure regulator valve? It is best to keep the pressure low and the mix at a high concentration--so you can cover more ground per tank. Add a gallon of water and spray cement to find out how many sqft you cover with one gallon.

    If I am not mistaken the solo backpacks have a pressure adjustment that you can make by turning a regulator on top of the pump inside the tank . They are numbered 1,2,3,4, 1=15 psi ,2=30 psi, 3=45 psi , 4=60 psi .
