  • Down Under use 5000psi.....

    I have been doing some home work and I have been checking out Aussie websites, and it seems they run alot higher psi than north america, Now I know these boys can drink beer and can put on a mean barbie, so are we behind the times up here, are we out to lunch here....running only 3000 psi, it makes sence to me to use a higher pressure? any thoughts

    seems like most of them are cleaning from the street back from the pics I have seen not from the house out. Besides the higher psi they are using smaller hoses as well. It was because of the aussie guys on here that I started using a higher PSI but I still believe that high GPM get the job done quicker and cleaner. The jetters edge web site has a lot of neat stuff for small drain cleaners while the american sites seem to be geared toward big municipal cleaners.

      as cuda has mentioned they tend to use smaller hoses that can negotiate the bends and cover the distance. i believe they use the higher psi to make up for the pressure loss due to friction of the smaller hose. therefore they end up with the proper pressure at the nozzle.

      5000# at the nozzle will do serious damage to clay pipe. therefore the tip pressure is probably closer to 3500#.

      high psi does cutting, but high gpm does the cleaning and flushing.

      psi is easy to attain. gpm cost money in the larger pumps.

      maybe i can ask when i'm there end of the week

                Spot on with your specs!

                Here is an early version of the first dual trailer we made. We use special check valves and other Aussie innovation to make it work.

                2 x 31hp 31 LPM Pump motor groups drawing from 2 seperate points on the tank at 4300psi. Combined it gives you 4300psi at 62 LPM or 15.5gpm.

                Have fun in NZ!

                  Re: Down Under use 5000psi.....

                  Well I will just have to try this as a local plumber who has a machine just like my jetter, 24hp honda,3000psi 8gpm is selling for dirt cheap and I thought about having two big jetters but if I bought a diverter valve and ran both at once I would think I had some serious power! Be nice to have a valve I could switch to using just one unit and then to both units when needed.

                        If the psi is the same on both machines (as you said) you can combine them, you will have 3000psi, 18gpm. If BOTH machines have trapping unloaders you just "T" them together.

                        A trapping unloader has built in check valves. If the machines have flow unloaders you can still combine them you just need to add the check valves and necessary adapters.

                        If you need help, I can supply you a vendor with a made up adapter with check valves.

                            Trapping means the power comes on right away? and flow is staged to gradually come on right?

                              I have never heard it expressed that way, so yea maybe.

                              If it is a trapped unloader the hose will be "pressurized" or stiff when the water is not flowing. If it is a flow actuator the hose will be limp, like when the machine is not running

                              So how many $$$ for this unit? If you are not interested I may be.

                              Also, you would need 27 hp to get 3000psi at 10gpm, so something is not kosher.
