Always. And for awhile now it’s setup with a ball valve on the 1/4 tube to switch between soap/ water. So i always finish rinsing the injector automatically while rinsing the house.
Are those the high draw GPs? And where are you buying them from? Maybe you got a bad batch?
You can open them up and repair them. I’ve done it. But it takes time to do that and it’s just easier to toss it and put a new one on since they’re pretty cheap.

Sadly, everyone could have bought a new injector for the time they spent discussing it…
I consider those possibly the most disposable item on our rigs. Keep spare(s) onboard with the QCs attached. If the crew loses more than 15 minutes, I could have replaced it.

I’ve used the repair kit that comes from GP before with success. It comes with an o-ring, ceramic ball, and a new spring. I’ve never used the o-ring, but the ball and spring I’ve replaced a few times. The kit is $7 maybe?
If you go that route, just be sure to reinstall the spring and the ball in the correct order. I failed my first time to do that and ended up having a decent trickle of water coming back through the drop stick and into my batch mix tank - resulting in a steadily-getting-weaker mix.

Don’t use wd40 on them.
Get a new supplier or let your current one know the problem you’re having and see what they say.

I don’t even think twice. Out with the old in with the new. Job done.

I’m not saying i’ll spend all day to fix it instead of getting jobs done. I do keep a lot of spare ones. But if i get 40 or 50 that can be fixed easily instead of throwing out, maybe one guy can get it done in a few hours in the winter or on a rainy day. I bought 6 of a new kind that i’ll test next.
It just gets ridiculous when you have to go through 2 injectors to wash a house sometimes.

That sounds like a crappy injector brand, or a bad lot for sure… I buy ones that run about $10, and they last a few weeks normally. By my math that’s about $25k worth of production give or take…I’ll just swap them out for half that revenue and be happy about it. Especially since we burn up way fewer 12v pumps since we went to downstreaming almost everything… 
It was $10 US…looks like they went up 10% this year…like everything else 
try using PBlaster, nothing else. its not a wd-40 clone. Ive used it on pump rebuilds for the ceramic and seal lube so its safe.

Maybe just use this one and stop worrying

Do you use these? Is the S.S. worthwhile? My understanding is the failure point is pretty much always the internal spring assembly, so the value of a S.S. body would be nil. That said, I’m intrigued by the 8gpm version that’s only $21 …
one would be inclined to conclude a SS body would be a nil benefit, but Id conclude that the SS body would be less likely to hold or promote corrlsion. Thus allowing the internals to last longer than their brass counterparts.
Lol, sorry I felt compelled to speak like this is me writings.

Yes it’s all I use. There’s a big thread on here that I read when I first started “best injector on the planet” or something. After both Rick and William praised them, I didn’t see reason to use anything else.
But don’t be interested in the 8 gom one if you’re using an 8gpm machine. Use the one I linked, 3-5gpm

Also don’t buy cheap stuff just because it’s cheap lol

While I am prone to that, if I can get $20k+ in production out of cheap, I’m in! lol
Why the 3-5gpm on an 8gpm machine? Seems like they mis-labelled them then, lol
You can’t consistently pull soap with 250 ft of hose using a five to eight GPM injector
