    beween the guage on the pump and the reel guage is about 60ft of jumper hose.

    worked awesome on 4" with grease !

    The true test for the new dbrr is 6" with roots... with the other inserts its just didnt finish it off as well as the single did.

    Even with the single barrel the pump guage reads 3500 psi and the gauge on the real reads about 4000psi

    ben i would guess thats the valve...

    We jetter a 4" pvc grease filled line 200' with the dbrr today...the machine ran for about an hr with no troubles .. sounded normal...the real guage read 4800 psi and the guage on the pump read 3600 psi
    I will admit, I am a little confused.

    the needle valve is a high pressure throttling valve used in hydraulic systems. if you can find a stainless steel one you'll be much better off than a carbon steel one.

    basically install a tee just after your outlet on the unloader. install the needle valve and pipe the outlet back to your holding tank, a bucket or just let it weep onto the ground. start up the jetter and throttle it to the right rpm. rpm will adjust volume and therefore less volume, less psi.

    if you need higher rpm to keep the engine running and cooling properly, then just crack open the needle valve to relieve the excess high pressure water and that will drop the psi. if you had a holding tank, it just recirculates into the tank. or in your case just a bucket or the ground.

    the problem with your present unloader setup is it recirculates into the intake water and as it does this, it heats up. it also puts excess wear on the unloader.

    Rick .. The needle valve doesnt sound like a bad idea. Could u explain a little more detail as the proper installation .. Thanks ..And i just watched the video of you and the dbrr again !

    ben remember the video i shot with me trying to hold onto the double rr while still holding the camera in 1 hand. i got up to 2500 and called it quits. 4000 would have pushed me over

    just think what a double at 4000 and up to 18 gpm will do. wanna come out and play

    you could fine tune it with your unloader, but realize that the unloader will dump it back into the intake of the water supply which will cause the water to heat up. since you don't have a holding tank. or better yet, install a tee with a needle valve bleeder and just dump a little water on the ground or into a bucket.

    4500 # will put a big stress on you hoses, foot valve, unloader and pump. not to mention the engine is straining at the higher psi.

    i'm using the same set up with my 4000 18 gpm machine. using the bypass and also using a larger nozzle as need be.

    very impressive wood cutting.

    Did you order it direct? Where did you find the orifices that you wanted? Was it Gear's place to shop?
