    How much pressure drop do I have ?

    3600 psi at pump with 5.5 GPM
    100’ 3/8” pressure washer hose going to foot valve.
    The 100’ of ¼” jetter hose and if needed another 100’ of hose

    I did read an article that said I am lousing around 1500 psi ?

    700 psi drop in every 100’ of ¼” and 100psi in 3/8 hose?

    Is this correct?????
    i am no good at math at all.

    just looking for a good explanation.
    or if what read is correct?

    easiest way is to install a tee at the front end of your jetter hose and measure the gpm and psi with the nozzle. this will also allow you to dial in your nozzles to match your flow.


    ps, we have the same pump and specs. i'm running 18 hp. with 100' of 3/8'' jumper hose and 125' of 1/4'' id jetter hose. i use a #5.5 nozzle with great results. wouldn't want to get near the end of it.

      not exact, and does not quite cover your situation, but you might be able to estimate/extrapolate from this

      The test t setup rick describes is the only way to be 100% accurate.
      This is my reminder to myself that no good will ever come from discussing politics or religion with anyone, ever.

        i seem to have a hard time getting 100' of 1/4' to pull the hole way?
