If I’m drawing at a 10:1, which realistically is probably closer to 12 or 15:1, How do I get the injector to draw more while down streaming? Is the only way to go with x jet or pump sprayer to get a stronger mix?
Get a hi-draw injector. Those are supposed to pull at 5:1 or even 4:1. Get one that’s undersized for your machine, for example a 2-3gpm injector if you have a 5.5gpm pump, or a 3-5 for an 8 gpm
Very helpful thank you. Would you recommend a stronger ratio when washing stucco? Also, why do I want to get an undersized injector?
Today i was wondering what would happen if you attached TWO injectors… 
You get an undersized to increase back pressure on extended hose lengths. You will pull weaker mix but at least you will pull.
Nothing
Ok so if I’m spraying with 100ft of hose, I definitely need to do it that way. Thank you
You dont need an undersized injector with only 100 ft of hose.
And dirty stucco needs a stronger mix than DS can put out.
The only way to get a stronger mix out of Downstreaming is to force feed the injector.
Bingo on what @Donte55 said. No need to downsize until over 200 feet. Xjet stucco, or better yet, just don’t do it. Much easier work out there.

In southwest Florida almost all homes are stucco. Unfortunately I can’t get vinyl siding very often here.
Xjet then. I’m in the land of vinyl here.

use a dual injector
I just got a high draw injector from bob 2 weeks ago. It is 5:1 draw and works great
Any chance you have a link?
Thanks instock. Not really sure how to post links… not very computer savvy
Thank you for that!
You have to be careful with stucco. If it’s old it will oxidize and if you leave the bleach on too long it will streek. We use 10% (volume) of 12% bleach in our mix tank for stucco and rinse before it dries.
Can you test it please, to see if it’s really is 20% pull one, because if you see just there on the site, the high draw injector kit at the Q&A there are two answered questions, and one of them states it is also a 10:1 pull injector.
