  • nozzle questions

    I figured I'd stop bugging Rick and throw my questions in the public forums. I was thinking of going with a 7.5 gpm at 3500 psi instead of the 6gpm and wanted a rootranger for those specs. I emailed the jetters edge about what RR would work and how much. The email I got back I didn't quite understand mostly because of how ignorant I am on the jetting subject. I emailed them back but maybe I can get an answer quicker here. Below is the email they sent me back and I just want to know if I need to somehow attach the rotojet to the RR or what. I am going to use 3/8" hose and I told them that. So from their email it looks like I am going to have to get a reducer from 1/2" to 3/8", is that correct? Also would that make it to stiff to navigate through 4" 90's? Thanks for any help


    "Thanks for your enquiry via our website. You would require a non-standard 255-070 Rotojet Nozzle on the Root Ranger to suit your pressure & flow which would be AU$350 + $AU$30 postage. This has a male quick connect tail or if you screw your heads on there is a ½” BSP female port. You may have to use a bush to adapt to your hose end, depending on what you have."

    looks like you're stuck with me

    i too have a 1/2'' rr. their 1/2'' thread in not npt, but bsp which is pretty close so a tap will clean it up.

    the 1/2'' rr is much larger in mass than the 1/4'' rr body.

    honestly i would stick with the 1/4'' body and the largest rotor they can fit. maybe they have a #7, 1/4''. if not they are easily available. the #7 will still leave you with some pressure for the small front jet if you chose to use it. personally i wouldn't.

    i use the 1/2'' rr with my 4000# 18gpm machine and it's a monster. i've blown back waste water over 50' with a full line.

    see what they have in 1/4'' specs and even if you need to downsize, i would stick with the 1/4'' over the 1/2'' to allow for 3'' fittings too.

      Ok so what is the max size pipe a 1/4" rr could clean with the specs i'm looking at? Also woud i have to tap the threads with their 1/4" rr or is that only on their 1/2"?

        the us version/ made for ridgid is already npt.

        with the extension nipple to keep it from turning around/ safety, you should be good to 6'' possibly 8''.

        ridgid has it jetted for their specs. you can go slightly larger.

          Alright so the jetters edge will take a 1/4" RR from ridgid and drill it out to handle 7.5 gpm at 4000psi?

            Re: nozzle questions

            i believe they have a #7 nozzle that is rated for 7gpm at 4000#.

            the ridgid spec is geared towards their 3055 numbers.

            i would stick with the 1/4'' body unless they have a 3/8'' body as the 1/2'' body and rotor gets to be quite large for what you're planning on using it for.

            nothing wrong with the 3/8'' hose as that will carry the volume you need. have them sell you a 3/8 fip x 1/4'' mip adapter for the hose, nozzle. or get a jumper hose made that's 2' long 3/8'' fip x 1/4'' mip. this will also save your expensive 3/8'' jetting hose from damage and act as a safety mark upon retrieval. very important not to pull back out of the pipe with it under pressure

            see what they offer as far as jet turbines, and adapters/ hose leaders.

            of course you can always get the double barrel rr and have them jetted at 3.5 each.

            i'm looking into a 9 gpm double rr now.

            i believe bill had designed a triple rotor at 1 time too.
