Chemical injector for downstreaming?

[rj242 16]

I have been using an xjet for washing houses, but have become curious about downstreaming after reading all the post on the subject. I have a 3500psi/5.6gpm washer and it came with what looks like an Adams chemical injector. My question is will this type of injector work? or do I need one of the higher draw injectors? I believe the Adams is suppose to go up to 20%, but they recommend a hose length of 100ft or less. I usually need 150-200ft of hose.

If my Adams injector is enough, then what would be a good Simple Cherry/12.5%SH mixture for downstreaming with this rig. Also how long does it take for the chemical to go through the lines (150-200ft)?

Any injector works fine with up to 200 ft of hose. Get yourself a gun made for use with high volume machines (12gpm+). I've used Simple Cherry at 2 scoops in a gallon of warm water plus 3.5 gallons of 12.5% plus to remove nasty buildup on vinyl with no problems.

Polish up your X-Jet.. it makes a pretty paperweight. I'm teasing, the X-Jet is still important in a professional arsenal for stucco or laying down chems on concrete. For vinyl though.. waste of time and chemicals.

Little under five gallons Randy. You wouldn't have any problem topping off with more water to fill a pail to the top.
