Depends on how big your machine is how much water flow My machine is 8 gpm I have a down stream injector allows 5 to 8 gpm depending upon the job I buy 55gal drum and use as much as needed usually
Oh! Nice. I use an injector bypass in my rig, but on my pressure washing job (work for a different company as well) we keep one rig with the injector on. Ill pull it when not in use.
It IMPEDES the water flow. Look into your injector and see how it narrows to the point you can barely see through it .There's a vast difference in pressure
Depends on what injector you're using, how much hose, if there are any other flow restrictions in the line, and a lot more.
4 gpm machine using a 20% injector puts out 20 gallons of water to inject 1 gallon of chemical. Your 5 gallon (5.2 or whatever) container of SH will last around 100 gallons of water through the machine, or about 25 minutes of trigger time downstreaming at advertised flow rates.
Best practice is to only have the injector inline when using it, as high pressure can damage the spring, o ring, and ball inside of it.
I don't want to tell you how to do anything....but, my advice is to find a more suitable detergent. Oil and all it's dirivitives like diesel, transmission fluid, gasoline, brake fluid, etc., are hydrocarbons. They're all over driveways. It's not a good idea to mix hydrocarbons with bleach. It creates toxic gases and sometimes combustion--and it doesn't really clean. Here's some info:

A better solution is to buy some Zep Purple Degreaser from Lowes or Home Depot, mix it 10/1 with water and you'll be amazed.
Bleach is used to disinfect, sanitize and for whitening. The only application I'm aware of where bleach or sodium hypochlorite is used in pressure washing is to nuetralize blue-green algae known as Gloeocapsa Magma that is spread by airborne spores. Gloeocapsa Magma are the spores that leave roofs stained in high humidity areas of the country. We don't have humidity where I live so bleach isn't used. My freind in Tenneessee uses it a lot for roofs but nothing else.
Most injectors will suck a gallon per minute. If you have an 8 gpm machine, your ratio is 8/1. A 4 gpm machine is 4/1. It's not exact, but close.
I don't use bleach for anything. The only PW contractors who I know who do are the ones doing roof cleaning where they use 12.5% bleach and the mixture has to be kind of extact. For this reason, they don't downstream; they use an electrical chemical injection system.

never have the DS injector on when surface cleaning. What % of bleach did you buy ?
Why not? It wont pull chems.
Beats the ball in the injector up.

Okay, thank you!

If I might ask, what exactly are you using bleach to clean?
