DOWNSTREAMING BASICS

DOWNSTREAMING BASICS

This post includes a video covering DOWNSTREAMING BAISCS for pressure washing business professionals.  We explain in a simple and basic manner how to operate downstream infectors.  I am a huge fan of downstreaming as it is the original soft wash method before soft wash became a buzz word about ten years ago.  So don’t miss a word of this in depth downstreaming basics video!

ADJUSTABLE DOWNSTREAM INJECTORS

One type of downstream injector is adjustable.  This just means you can adjust the chemical ratio that comes out from the downstream injector.  The fully open position allows you to get highest mix ratio possible.  Conversely, as it moves toward the closed position, a lower mix is the result.  In my years of experience, I never really saw need to close it.  So I quit using adjustable downstream injectors.

FIXED INJECTORS

The fixed injector has no flexibility in terms of mix ratio.  This is a popular approach because it is a fast, easy way to apply the solution onto the surface.  In fact, I sell the GENERAL PUMP HIGH DRAW INJECTOR through my Doug Rucker Store.  It comes in either 3-5 gallon per minute or 5-8 gallon per minute.  We use a schertzbox remote to turn the chemical on and off, saving time and effort when rinsing.  Be sure and watch the entire video for more insight such as using check valves with downstream injectors.

MIX RATIOS

One of the most complicated aspects is calculating precise mix ratios.  Regardless of the ratio calculation, the main concern to look for is whether the mix is changing the color of the stain on the surface.  Double ports do not increase the mix ratio.  A double port simple delivers more of the same ratio mix from a single port injector.  I also explain our JROD nozzle system that includes our shooter tip.  There is so much more in the downstreaming basics video so be sure and watch it all!  There are a few OTHER PRODUCTS which I find extremely helpful in my business.  I can’t recommend these to you highly enough!
