@jordanafunggol9543 you can get a general pump chemical injector 2.1mm for a 3-5gpm machine. It is rated as a 20% draw although they do fluctuate depending on the tips you are using to apply the chemical. You can draw directly from your SH tank. You will get anywhere between a .8-2% mix. You should get the injector and do a draw test by measuring out 1 gallon of liquid and dropping your draw line in. Run your machine until that gallon is gone and then do the math for how many gallons of water you put out to use up that one gallon of test water (in place of your SH). I have found that with my machine I draw less chemical than the injector is rated for when I do the draw test. This is all estimation, don’t get too stuck on exact output. It is rare to get too strong of a mix when using a chemical injector. Give it a test and let me know how it goes.
Thank you so much for the swift reply. I did a ran test and with my machine draw a 1 gallon of chem (water for a test ran) and 4 gallon of water coming out from the tip of my lance
@jordanafunggol9543 yikes! That is a hot mix. What are you using for your injector? If you start with 12.5% mix and end up with 4 gallons of total output and one gallon of that was SH then you have a 1:3 ratio. 12.5% divided by 4 (total parts) is equal to 3.12% SH. That is about what you would need for stucco or brick. Don’t wash vinyl with that or you will oxidize it.
Hi Brandon, Informative video. Where do you buy Lauramine Oxide and Superscent Lemon from? Thank you in advance for sharing the infor.
I get mine from Wesmar Co in Seattle.
You’re welcome!
Hey Brandon
I would like to ask how can I achieve the 1% solution out of 13.5 % SH if I have 4gpm machine
