Can Someone Describe What Downstreaming Is?? Thanks!

Hi Guys,

Another basic question, but im having a helluva time getting a definition on the board... I have a 3600PSI cold / 4GPM unit w/ a chem siphon (not sure what ratio...not quite sure how to find out..) Anyways, when i apply my detergents for flat surface cleaning I usually mix a concentrate in a 5gal pale and use the chem siphon to attain my H20 mixture...

Is this "downstreaming"?

If not, could someone be kind enough to educate me? Thanks Again!

If the injector is on the high pressure side and you must use a lower pressure to get the chem flowing, then yes it is "downstreaming"

yea, that is downstreaming (as Alan said, I also assume your using a soap tip (the black one) to allow the injector to draw the chems)....... 4gpm with a 3600psi pump, my guess would be your ratio is 12:1....

hope this helps

Thanks guys.

So, if my unit is giving me a 12:1 ratio, it would make sense that I would need to fill my 5gal. pale w/ straight bleach/soap/tsp,etc... and NOT with any water? I know everyones cleaning 'concoctions' will vary, but for general non-wood flatowrk where removal of mildew/moss/agae/gen. soil is desired would that mixture make sense?

Before learning more about detergents, I use to mix the 5gal. pale with bleach AND water!... Seemed like a pretty tame mix though...

And is there any procedure for cleaning out my chem siphon after use? Say, using my black soap tip with straight soap and/OR straight H20?

Thanks!

definitely no water. In fact on flatwork I am surprised you can downstream at all and still get decent results.

Why The Low Pressure If You Are Using A Black Tip..the Chems Come Out Anyway.?

The black tip is what is lowering the pressure.

The black tip is what is lowering the pressure.

and allowing the injector to draw the chem out of the chem tank (jug, pail, whatever)

Ken, why would you think downstreaming on flatwork would seem unlikeley to produce any results? Just curious... Thanks

[tropical wave 22]

probably because the water ratio is too high when downstreamed to get the concentration of chems on the surface to be cleaned.....but thats a guess on my part

i feel it works better at 20% .....you will get better results but thats just my oponion

I hate to be a stickler, down streaming is simply by-passing your pump with what ever your spraying. up stream down stream... its applying chemicals with your PW.
