This DOWNSTREAM INJECTOR VIDEO focus is on how to go from bleach to water when you want to rinse.  Here are direct link to the downstream injector kit that is part of this video.  In addition, I talk about the various nozzle sizes and options and how they affect downstream flow.  One of the great features of this DOWNSTREAM INJECTOR VIDEO is actual demonstration footage of various nozzles and their different spray patterns.  Understanding the two reasons why we call it downstream injector is vital.  First, it’s on the down side of the pump so no chemical is going through the pump.  Second, the injector puts chemical into the line and sends it down for spraying.  Be sure watch this entire video to get all the details.


At the 2:00 time stamp in this DOWNSTREAM INJECTOR VIDEO, take note of the arrow.  It’s a small arrow but it’s vitally important because it’s pointing in the direction the chemical will flow.  After applying the bleach, the next step is to rinse the surface.  In the old days, we would use the various color nozzle tips depending on application versus rinse.  We would use the black tip to apply the bleach, then use the red, yellow, or white tip to rinse.  The question I get often is how to rinse without having to change nozzles.  There are a couple of ways to do this which I explain at the 4:00 time stamp.


But then a new nozzle option came along.  So the question now is how do I stop the flow of the bleach with JROD nozzles?  Two of the nozzles have larger holes like the black nozzle which lowers the PSI of the machine.  This is what allows the bleach to be injected into the flow of the water.  You can rinse with these two nozzles by switching the injection syphon tube from the bleach bucket to a water bucket.  Or you can rinse by using the other to JROD nozzles which lower the PSI of the machine.  If this video is helpful, please check out my online video school.  This is a great way to get the training you need to start and grow a successful pressure washing business.  Please don’t hesitate to leave a comment with any questions you might have about this DOWNSTREAM INJECTOR VIDEO.

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!


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.


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.


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!
