Chemical Injector Size?

What size chemical injector to use for a 4.5gpm machine with 150-200ft of hose?

I ordered one for the 3-5gpm but I’m reading that maybe I should go with the smaller injector due to length of hose?

Is this true?

Also would the mix still be 2 gallon Sh & 3 gallon h20?

Uh oh did I finally stumped the big dogs?

I am new but generally you want to go down one size to increase the amount of sh you are pulling. Really it’s whatever works best for you.

I have a 1.8 and a 2.1 injector for my 4k/4gpm machine. I run 200ft of hose 90% of the time. They both will drain a 5 gallon bucket quick lol. Not really a noticeable difference for me. The 1.8 will restrict the flow alittle.

No. Your question had been asked and answered dozens of times in the last year alone. Just gets old repeating the same info over and over



Steve deleted a pretty asinine comment from a poster that had only been here for 8 minutes and between the comment and how fast Steve caught it I can’t stop laughing.

Like a sniper.


Lots of weird, new posters recently


It’s fairly reasonable to assume this particular guy was definitely $99 guy because the comment was essentially “who uses the injector?” Hahaha


I prefer the term “Keyboard Commando” thank you.



He also started a thread that I deleted saying that softwashing is a scam and high pressure is the only “real” method of washing things, but we’re all too scared to do it etc… and blah, blah, blah…


I just said to my wife this morning “here comes the onslaught of weirdos that Winter always brings for some reason.”


He could have been some good entertainment. Yall are no fun​:joy::joy:


The problem is when we let the crypes and awesomewash’s of the PW world be our entertainment for even a few posts they inevitably go off the reservation and turn into pains in the neck that are sure to run off new readers or give info that gets them in trouble or makes the rest of us look like hacks… it’s best to quarantine them to their own world of insurance claims and/or failing out of business.

Or yeah… letting people have at this last guy could’ve been incredibly entertaining lol.
