Injector with check valve

It came with one already mounted. I just screwed it in to the injector.

Now you tell me, lol. Did you flush it like regular injector? What went bad?

I always flush my injector at the end of every job.

What I think happened is that the clapper inside corroded around the edges or the gasket inside broke down. When it was new, you couldn’t blow any air through it against the valve, now you can blow air through it very easily, but you can still hear the clapper moving inside, just like it did when it was new. It seemed to happen pretty suddenly. It was working fine, and then it started back feeding through the check valve. I think it was corroding the whole time, and it just held up until the SH finally wore a hole somewhere around the edge.

I haven’t taken it apart yet, but if I do, I’ll post some pictures.

So what’s the consensus, @Racer, after further testing? :+1: or :-1:

@Racer are you still using the injector with the check valve?

Yep, I like it. Does pull about 20% more mix, but works flawlessly so far. If house not real dirty, I just add a tad more water to my mix. The good thing is that unless a lot of embedded algae in concrete, I can usually just post treat down streaming. Plus when you have like a front stoop that the steps are really dirty, I’ll just hit with mix and let sit while I do back of house and then just come back and soap it again and my m5ds nozzle will clean it right up. Beats having to pull out my 12v.

Link to check valve?

I think he ordered this one from above:

Ok, thought he put one together, looks like about 20-25 to make it yourself. Thanks!

No, ordered from Wash-skids. He’s the one who sells them to Rucker.

LOL, good luck on that

It’s just a 1/4” stainless check valve and 1/4” stainless barb right? Or no?

Can you link?

You sold me. I’m gonna try it. Hopefully it lasts longer than a regular injector.

Are they cheaper from wash-skids?

What size is adapter is it from the check valve to the injector? I’d like to build one too so I’m not reliant on buying a $110 valve every time I need one.

I tried finding his website but it would just redirect back to his Facebook page every time

I was never able to figure out exactly what type of threads it was. So this was my solution:

But I’m sure once you had the $110 injector, you could reuse the adapter it comes with and just buy the $18 check valve on Dultmeier or wherever.

Is the point of the check valve to just get rid of the ball and spring in the injector?

Yes from what everyone has said. Basically the most frequent reason they fail.
