Chemical Injector Help

Any help with this would be great!
I can’t get my chemical injector to work at all. I haven’t added additional hose, I repaired my entire unloader setup, I’ve replaced my entire chemical injector (ball, springs, check value, everything) and still nothing. Does anyone have idea what may be causing the problem?
Psi is proper, water flow is good, the right tip. It’s such a pain in the ass

Sounds like you have covered most everything, assuming you don’t have it in backwards, I’m puzzled to.

There realy is no puzzle with injectors, when they stop working, snap a new one inline and continue soaping.

If you want to confirm the new one works, hook one piece of hose to your pw’r with no gun or valve on the end and see if it draws soap.

I thought he said he replaced it with another one, my bad I misread it.

make sure its not in backwards

The injector is technically new, all of the parts after the unloader were replaced but still nothing. It’s a built in one not an attachment and none of my attachments are working either for drawing soap. Any other help would be great!

Somebody will come along and suggest that you should consider purchasing a unit meant for commercial use but sometimes people get offended by that so I don’t want to be the one to break the bad news to you.

But it is a thought…

Its a decent machine and had held up well, it runs 5gpm, 3000psi. It’s perfect for my house washing. Are those specs not considered commercial?

Thanks, Seab

I can’t speak to your machine but 10 to 12 minutes is how long it takes us to change out a downstreamer and get back to making money.

Time management means a lot. If you are happy with your machine, it is certainly not my place to say that you are wrong.

I wasn’t offended by the comment, I was just asking if the specs were considered commercial. I’ve changed the injector many times but for some reason it’s not having it this time around. Could it be any other reasons aside from what I mentioned?!

Thanks, Sean

If you remove the injector and take it back to the basics and it works without the injector then you have found your problem.

Do a little troubleshooting to help yourself out and get better responses to your questions on here.

Every hour you are are down is $100-$150 or more, if its the injector and it still doesnt work after verifying the actual problem then call it a day and get a new injector.

Only other thing I can think of (if its not the injector) is that something is causing back pressure not allowing the injector to open. This could be caused by…wrong size injector…low gpm rated gun…soap nozzle too small. Trigger gun should be rated for 8 + gpm. I do remember a few months ago Bob said General had some injectors that were not sized correctly and worked when drilled out…other than that I got nothing.

[MENTION=7366]GuyB[/MENTION] : I have two of the exact same machines and a bunch of extra parts. I took apart the entire thing from the pump out and didn’t see any problems. Putting everything back together I noticed it was pulling and then I realized my hose reel is causing the problem. The hose pulls fine but when I plug the hose into the reel it stops. I’ve never had this problem before.

This happened with an order of injectors. I thought my pressure washer had crapped out and ended up looking through the injector and it was a pin hole size. Ended up having four more just like it even though they said 5-8 gpm.

What some people didn’t read was the comment where you said the injector was built into the pump. Typically this is what comes with machines that you buy from places like Lowes or Home Depot or other department stores. What they call commercial pressure washers is not what we consider commercial. When you have harsh chemicals running through a piece of equipment for 12 hours a day it’s going to go bad often and you should be able to just unhook it and have a new one put on in the matter of a couple of minutes. If this is a machine that you use for just washing your home than there is nothing wrong with it but if your start washing professionally and use it often then your going to run into a lot of issues eventually. If it’s not working when you hook it up to the hose reel than there is something in the reels plumbing that’s clogging it at least partially and causing it to create too much back pressure for your chemical injector to open. Either way eventually you are going to have to replace more than just the ball, spring, and o-ring in that injector if you use it often.
