Here's my message I pass along on Facebook and Reddit about this subject the 1.5mm, 1.8mm, 2.1mm, 2.3mm, 2.5mm is the orifice size that's inside the injector. This varies your draw rate. These are general pump sizes Metric-Inches- similar tip size 1.45mm-0.057"-(5) 1.5mm-0.059"-(5.5) 1.6mm-0.063"-(6.25) 1.8mm-0.071"-(8) 2.1mm-0.083"-(11) 2.3mm-0.091"-(13) 2.5mm-0.098"-(16) The smaller the orifice means higher pressure which means a stronger draw through the venturi effect Also like an xjet your gpm is also going to vary your dilution ratio.
@@TheFreshRinse they both work hand in hand with each other because just like nozzles smaller orifice means higher pressure and lower gpm so it's less diluted but also at the same time higher pressure from the smaller orifice is creating a stronger vaccum through the Venturi effect on the other size of the orifice where the barb is bringing in chemical faster. I would say with a stock injector that has the same barb size, the orifice makes the bigger difference in dilution more than the pressure created vacuum does. Reason being, the barb could and probably does restrict how much more chemical could come in with the higher pressure created vacuum. If the barb were larger to not cause restriction on the chemical intake then I would say the pressure causing vacuum would be what makes a stronger mix more than the amount of flow the orifice allows.
With all the tropical plants down here in Florida I use the 2.3 however I do use a 2.1 when the algae gets super bad, great video Mike. Downstream is a fantastic way to clean.
I soft washed my house (well x-jet) for the first time this weekend. Thank you for your videos…. I saw my neighbors watching, wondering “what is the mysticism?” Seriously tempted to go into business for myself!
I exclusively use 2.3 during spring and summer and I'm super fast and efficient. I even sometimes close my 3 way valve to my bleach a tad. Come late fall and early winter I go with a 2.1 or 1.8. the comments that state that a 2.3 is a chemical saver are spot on and I get the same, fast results during warm weather
Like your video/info. Mike 👍 And Yep, ordered & changed back to 2.3 DSI last month for my 8gpm as well after a few mishaps in this heat. FYI, a Gardener said that even watering plants if very hot, direct sun, dry conditions can cause problems with plants. Recommends a very Light mist/fog to cool, second heavier mist to wet, and even a third pass to soak… then you can wash/ rinse. Im also adding a neutralizer for a secondary pre or post treatment. It’s definitely more work/time/cost but, I can’t afford to destroy any more plants. 😢
@@TheFreshRinse I am looking to get the raw chem (can’t recall tech. name) and mix my own, I was using “Agent Halt” from The Power Wash Store in Nashville when I started out but there are several brands on the market.
I appreciate the test and it gets me re-evaluating my own process. I have ordered by accident when I didn't know any difference; the 2.3 and didn't notice any difference. But something to consider in your own process is that when I am using a 2.1, I am typically using a batch mix of about 10% SH, so that means that my off the gun mix is probably about 1% with the 2.1 and when you did your house-wash with straight bleach and a 2.3 orifice, you are probably also about 1% off the gun. So there are different ways to accomplish the same thing and I think your test is about exactly what I would have expected. As an additional point, I have never felt the need to switch the orifice size and have just accepted that my hottest mix is going to be about 1.2% and if I need hotter then I switch to a roof pump or XJet and so far that has been fine.
You are probably right, I just assume when it is cleaning good then it is in the 1% zone. Well I can also tell by the amount of sting in my eyes between hot and not. Super scientific I know.
I agree with your field data. I have only used a 2.3 with a igx 800 10gpm. When it is in the 60degree range and less I usually have to reapply the solution. Good video. Good suggestions.
Did the homeowners say you killed plants or did you notice? I haven’t killed anything in 2 years other than my own grass at home when priming my 12v lol. But seriously just wondering. I bought a 1.8 injector and didnt even think to be more careful on plants. Does that 1% if even 1% make that much difference on plant life?
Yeah, pretty much. I’ve killed a few. I never argue. If they feel the plant(s) are toast, I say “Please let me know what I can do to help resolve the situation. I’ll stop at nothing to make it as right as I possibly can.”
I determine it by the temperature. Sounds crazy but, when it’s cold I use the 1.8 because it’s more potent. When it’s warm I use the 2.1. And when it’s hot outside I use the 2.3
The orifices from there Not a dollar Each. They are 3.50 each Plus shipping. If you happen to find them anywhere for a dollar, let me know cause I need to buy some more. Thank
I heard a rumor that you don't use surfactant on roof washs anymore? Is that true and why if it is? I am new to the game and have done to roof washes both was her fact that I'm wondering if the extra expense is necessary.
Would you say that a 10gpm would be too much? I'm thinking that a 10 could be quite versitile if configured properly: you can do both flatwork and house washing without having to jump around between different machines. Just thinking out loud.. let me know what you think
@@TheFreshRinse Yes, I can imagine with all of that power! Would you recommend using dedicated softwash systems for roofs/houses and just downstream for flatwork?

I’ve heard of guys that work that way, one guy soaps the other follows and rinses, (some guy up in CT maybe, LOL) my son and I just divee it up when we arrive, “ I’ve got near and rear, you do front and far”. As a solo act Fresh, you get to drag your two guns and hoses around and soap and rinse at the same time. Good luck not running out of water with an 8 and 10 sucking you dry at the same time. We run 2 6s and struggle to maintain water in the tank, or as Joe says, “chasing water”. Keep up the great work guys!
@@TheFreshRinse yes….you did say that. I was thinking for you long term, 2.1 would be the go to injector for 8 gpm. I’ve tried 2.3 myself…..seems like longer wait times and more applications, but that’s me. Thanks for the videos, their great.
Maybe you killed the plants like I did that one time on a house because I forgot that I did not switch my down the stream injector back to rinse 🤣🤣🤣🤣 talk about a big "oops"

Thank you. Are you sure it’s the small hole/pressure combo that draws a different ratio? Or, is it large hole adds more water, thus diluting the mix?

You can change the orifice out with the quick connects on. Asduming your allen key is long enough.

I’ve had several customers call. I get it. It doesn’t seem right. I can only chalk it up to the severe lack of rain.
Thanks Mike great information to know.
Thank you my friend
I've been using a 1.8 with my 5gpm. Been working great
That’s a powerful combo
@TheFreshRinse Yea, I have been sure to wet everything very well, so far I've haven't had any issued lol. I may switch back to the 2.1
Another knowledgeable video! Thanks Mike
@@kmc669 You are very welcome brother
Hey Mike! Wouldn’t you be better off doing a better job watering plants than changing the size of the injector?
That’s a great question Jose. As the temperature rises, a strong mix is not as necessary. Perhaps doing both would be beneficial.
Love this information for sure.
Very valuable.

Great video mike! Very informative!

Awesome brother!
Thank you kind sir!
How do you determine SH percentages when using the different orifices wirh different gpm machines?
I determine it by the temperature. Sounds crazy but, when it’s cold I use the 1.8 because it’s more potent. When it’s warm I use the 2.1. And when it’s hot outside I use the 2.3
Where do you buy the replacement orifices?
Southside Equipment in Kentucky.
@@TheFreshRinse Thanks sir
any way to test the water to get an exact mix ratio? pH testing strips or something?
It’s a great question. I’m sure… but in the end, if it eliminates the organic growth, it’s strong enough. Still a great question.
What size injector would you recommend for a 4gpm?
2.1 or 2.3

Prices increase all the time. I would encourage you to buy them at $3.50 as you can. $3.50 is the new $1.00
So I should stick with the 2.1 with my 5.5 gpm
Yes sir
5.5 comet pump with a 3 orfice in a super sud sucker is getting a 14:1. That with 12.5 sh gives 0.8% final.

You can go ad low as you want. A 1.8 will work. Probably a 1.8 would do great.
