Downstreaming + Dual wand question

Hi Everyone.

Well, my machine is showing up this coming monday, finally (been waiting for awhile)

Until then I have to rent a hot water machine to get some work done on some heavy equipment this weekend.

I rented the machine last weekend (yea its a pain in the ass, but better then nothing) and it had a dual wand and I was trying to get the chemical injector to work but it wouldnt suck anything from the bucket. Is there supposed to be two tips on the dual wand, if so there was only one tip on this wand and when I turned the handle on the wand the one side (w/out the tip) would stream out like a hose. Is this correct? If so what am I doing wrong?

Of course the company I am renting from is saying it should work but its not. It would sure be nice to at least be able to apply SOMETHING to these machines instead of just using hot water.

As mentioned my real machine will be here monday and I am looking forward to having a complete setup and really being able to do some grade A work.

Thanks for any help, I have to do the work Saturday early am, so any ideas/help would be appreciated!

All the dual lance is doing, is adjusting the pressure. You will still need your soap nozzle to apply chems and another nozzle to rinse.
 
So the lance SHOULD have another nozzle on it.. I thought so.. because it doesnt right now.. I thought it should so it would create the low pressure suction and then you rinse with the regular nozzle..

Thx for the reply!
 
No, not another nozzle as such. You need to swap nozzles as you would on a single wand. Just as if you were down streaming. One side of the dual wand is only for releasing pressure, so that you can regulate the pressure you are washing with.
 
Pops,
A dual lance normally has 2 nozzles. The high pressure you rinse/wash with. When you turn the valve, it adjust the pressure by diverting water out the other nozzle (normally a soap tip) when the pressure drops to about 800 psi (depending on which injector you are using) then it should start drawing chem.

So, if there was no tip in the end, and the water was diverted via the valve, the pressure should have dropped and chem would have been drawn.

On a single wand thats what you do when changing tips from a small (wash) to a large (soap), just dropping the pressure so the downstream injector draws chem

Different ways, to get the same result.
 
You need a bigger orifice tip. It doesn't matter the pattern. I have a zero tip that I downstream with (You can also use a hose barb). I believe Bob from pressuretek.com told me that it needs to be AT LEAST 30% lower than full pressure. Not sure exactly. All I know is whatever he sent me, kicks butt.

so by say you can't run a single tip wand with the 15 degree and get chem in through the lines, you need to run a soap tip or so and the injecter will then pick it up.?? sorry don't no just a new b

I'm glad to see you found an older thread on downstreaming Gary. Doing a little research always pays off. If you would like to downstream, and use only one nozzle, try one of these.
 
Finally got my little electric to downstream better. The soap tip it comes with is the same size as the soap tip for my big washer....a 40. At only 1.5 gpm there aint much happening through a 40. Got a bunch of 15 degree tips, 5 through 30. A 5 wouldnt pull any chem, a 10 just started to pull but not enough, a 15 is perfect, pulls plenty of chem but still has some umph behind it.

Ron...it's been awhile since you were behind a wand eh? :) Better get that oring fixed too, caustic leaking on a battery full of acid doesn't make a good combo.

Good video though, good job explaining how the DS'er works and how simple it is to use.

Ant I miss you man whats been going on ?

oops Ron did I just hijack your thread ?

Ok wait , its a great tool get you a couple per rig today call Russ Johnson !
 
Couple of things. Rental machines with the built in downstream injectors are notorious for not working due to abuse/ or never being used. Or never being set up. I would not base my desision on that one time. I find that a downstreamer on the jumper between the machine and hose reel works much better and can be changed out in seconds as oppsed to having to pull the machine apart at the unloader for "built in units", also diffrent injectors can be changed out for diffrent draws very quickly.
I use a dual lance with a 40 soap tip with a 4.0 turbo tip on the other side. Once chem starts flowing you can split the chem to the turbo tip to give more "ooomph" to the application to knock off alot of junk real quick.

I was hoping to meet you at the NO rountable, but you didn't show man. I wanted to call you and tell you I'z coming, but then we wouldn't have had the element of surprise. :)

Anyway, the last couple weeks I have had a sinus infection, both ears infected and fluid in my lungs (mild pneumonia) and haven 't been to fun to chat with :(

It started when I went to Nawlins...
