I just recently got a Downstreamer and it pulls a 10:1 ratio. My Bleach is 10%. So If I were to DS the bleach bottle I’d only be getting around a 1% mix. But I heard that in order to Pre and post-treat concrete driveways 3-4% is recommended. I’m only asking because I see people post-treat with a DSI. I have a 3.5 gpm 3800psi pressure washer and this was the DSI I got here
Man, read here for a while.
I’ve read trust me I’m confused and asking for a bit of guidance. I just want a simple answer. If you know the answer then let me know if not don’t fill up the thread.
The irony of you saying don’t fill up the thread about a topic that’s been explained in clear, concise terms on this very forum is…ironic.

3 great links an all i had to do was click on the magnifying glass and type “downstreaming driveway”
People on here are all pretty much professionals so you are expected to do the legwork yourself, and if you need further clarification, then ask. To be spoonfed answers is not good for you in the long run.
So you could say something like “in this thread, i had a question about how _____ was actually done. I have tried such and such but am still confused about this. Could someone elaborate on that method?”
As opposed to just getting on and blurting the first question that comes to mind without actually researching.
Ill tell you my 2 cents because im a softie. First, you need to figure out if youre legitimately pulling at a 10:1 ratio because thats just a number on a paper until youve proven it through your system. To do that, do a bucket test. If you ask what a bucket test is without searching for it im gonna brain ya! 
Then youll get your actual ratio and be able to figure out what youre really pulling. I know a lot of people that DS onto a driveway as well and it comes down to how gross the driveway is. I personally hit driveways with a 2.88% ish mix because thats convenient for me to do with my xjet.
Try DSing a driveway and see how it works for you. If it doesnt work, back to the drawing board and raise your SH to 2-4% and see how it works for you. An easy way to do that without spending a lot of money is to buy a pump sprayer and while not ideal, old faithful will be there to help you out whenever you need hotter mixes.
Welcome to the forum. I say this with all respect but try not to ask a bunch of dumb questions, so that when youre REALLY stuck on a tough issue, youll have people there and willing to help you with their expertise. This forum here is literally the best dang informational forum ive found on the internet about its subject. The amount of knowledge in here and freely given is mind boggling if you only search for it.

Once again, the search bar will be your friend.
Downstreaming a driveway is absolutely do-able. Downstreaming stucco is do-able. Downstreaming a roof is do-able. BUT, it all depends on how dirty the surface is that you are trying to clean as well as how clean you intend to leave it. Most folks won’t clean their stucco or roof often enough to allow for the weaker concentration of a downstream injector to work and therefore that is why they typically aren’t used to do such. Same could apply to a driveway…every scenario is different.
Why don’t you tell us a bit more about YOUR setup as well as any specific jobs, with photos, you are trying to tackle and we’ll be able to assist you more. Otherwise we are just speculating.
Uh oh. You filled up his thread. Big no-no, mister.
Say my downstream injector is a 10:1. My question is how do I get a higher percentage when if I were to DS straight from the bleach bottle id only be getting a 1% mix? am I supposed to be pulling from a bucket that has a 2-4% mix? if so I thought the downstream injector dilutes it a ton.
How would I get a higher percentage? and this is after genuinely searching and doing research.
I think you answered your question…eliminate the diluting piece of the equation…
So don’t downstream? because that’s the only diluting piece in this equation.

If downstreaming means you are only capable of getting 1 percent you need to do something else that’s not downstreaming
So then how do other people do it? I have a 3.5 Gpm pressure washer and 10%SH what else do I need?
You need to introduce yourself. Tell us who you are. Buy a pressure washer. Forget about ratios, they are meaningless.

Ok in a nutshell, you’ll probably get about 1% concentration out the gun downstreaming straight 10% with that machine. That’s it, all it’s capable of.
If you want a stronger mix you’ll have to get a separate system such as a 12v that has the capability to draw straight water all the way up to straight bleach depending on mixture.
Where are you researching?
