  • Pressure washer-jetter conversion

    Just got a 2.4 gpm 2400 psi gas pressure washer. Looking to get hoses and was thinking of US Jetting Micro jet hose. It's 3/16. Or maybe I should just get 1/8 hose? I plan on using this for 2" and smaller. What kind of hose should I get? Also looking to get some accessories. I already have a foot pedal but here's the other stuff I was thinking of.

    -hose reel-Only needs to store 100' or less of hose
    -jumper hose
    -unloader? I have an AR RMW series pump. Do I need an unloader for something so small?
    -hose and nozzles

    Looking to get most of this from water cannon but am heavily leaning on the us jetter hose. Anything else I'm missing?

    ben, the unit better already have an unloader valve. looks like an adjustable pressure regulator.

    i would stick with a 1/8'' npt hose with a 3/16'' id.

    100' of small hose is easy to wind up on a $10. home depot plastic electrical reel. like used for extension cords.

    sounds like a 5.5h.p gas engine.

    get nozzles drilled for a #3 max. all rear will do you much better. limit it to kitchen and laundry lines.

      no unloader valve. Here's the pump on it. https://watercannon.com/pc-796-155-a...-rmw2g24p.aspx

      So how does hose size get measured? The 1/8 with 3/16 interior has me confused.

        ben, please save your money and buy a better pump. i can't see anyone using a vertical shaft pump.

        this pump has a built in relief valve according to the specs.

              Guys,

              A pressure washer that delivers 2.4 GPM will produce around 770 PSI of pressure drop in 100' of 3/16" jetter line.

              This means that you can use a #4.2 custom-machined nozzle (like a 1/8" Aqua Mole that costs around $27) without overloading your pump rated at 2400 PSI.

              If you're using a good quality nozzle (like a Suttner nozzle for around $20) you can use a #5.5 nozzle without overloading your machine.

              If you're considering a $10 consumer-grade nozzle sold at many online parts stores (typically stamped "CHN") go with a #6.5 or larger size because of looser manufacturing tolerances. This size of nozzle delivers significantly lower cleaning and pulling pressure.

                I strongly suspect the us jetting hose you mention is exit-flex dp 1.3. Harben sells it also. Great hose. Best I've found for 2" lines.

                1/8" refers to the npt thread on (one) of the fittings. The other is a flare fitting. No idea why.

                the 3/16" is the hose i.d.
                This is my reminder to myself that no good will ever come from discussing politics or religion with anyone, ever.
