Anyone got a parts list for this two step gun? In particular that 3-way valve, and the adapter that goes into the injector?
I’d like to piece something together that’s a little more sturdy than my xjet and poly ball valve solution I used last year for the big psych facility job. I’ll be doing it again first week in August 
So, follow up question:
I’m going to be doing everything at low pressure. How large can I bore out the orifice of the downstream injector if it’s being used at the gun, with low pressure house wash tips?
One article from PTek indicates you need a 30% pressure differential for the injector to draw soap. My housewash tips only put out 80psi.
So by that logic, if I had the orifice drilled out to generate only 120psi, it should still suck. That doesn’t seem quite right to me, though.
Does anyone know what size orifices are in the xjets? That might help get me on the right track…
@dperez, you seem like a guy that might know such a thing… 
I have never messed with a xjet but I would guess they are 40 45 and 50 sized orifices.
You’re hole size would be .156" to .172"
5/32" to 11/64" with wire gauge size #20 being right in the middle
Thanks, Dezmar.
I think you’re probably thinking of the the spray tip orifices, not the pressure orifice inside the xjet body. I should’ve been more specific.
I pulled out my drillbit set and used them as a size gauge on my 4-6 gpm xjet. The orifice on mine is just a hair under 3/32”, or .094”. That lines up with a #13 orifice nozzle @ .091”.
Looking at a spec sheet for the xjets, the 4-6 gpm model is labeled XJET-13K. So it appears that they use the actual orifice size in labeling them. Pretty handy!
So all that said, I think I should be more than safe drilling out my DIY 2-step injector to 3/32”.
I got one I could loan you in a week or 2.
It puts out soaps @around 800 psi ish rinse around 1500 psish. Just got to screw on your own lance and run 1/4" lines @Infinity. Has 3 different nozzles that will work for a 5.5/6 gpm. The injector is a 1.8
Yeah I didn’t feel good about knowing what’s going on lol
It’s coming together…
I had to use a non-standard injector that came from who knows where. The gp hidraws do not have 1/8 npt on the soap inlet. But this one did.
Unfortunately, I already drilled the fixed orifice out of this one (pretty sure to 1/8”). That’s a #25 orifice, putting me right around 200psi at the injector. Still enough to pull chem, I hope. Can’t wait to try it out tomorrow.
I tapped the ends of the hose barbs to be able to use the screw in metering tips from the Dultmeier stainless/kynar injector. For anyone interested, it’s an 8-32 thread.
I was PM’d for a parts list.
Unfortunately, I can’t give exact model numbers and such, since I opted for some low pressure fittings for the sake of expediency and convenience, and I know for a fact that high pressure tips will never go in this gun. But that’s not a ‘best practice’ by any stretch.
Also, I have this mystery injector that happened to have 1/8” threads. It might be a JE Adams 10% fixed injector? I think it would be much more preferable to find the correct adapter for the soap inlets on the standard injectors.
For my gun, I used:
•(2) 1/4” fpt x 3/8” fpt adapter couplers
•10” x 1/4” stainless nipple
•1/4” fpt x female pressure coupler (stainless)
•1/4” fpt 3-way PVC ball valve (MFR #: 6900190)
•(2) 1/4” mpt x 1/4” barb elbows (Banjo MFR #: HB025-90)
•1/4” mpt x 1/8” mpt adapter nipple (substitute this part for whatever thread is on the injector of your choosing
An 8-32 thread tap was used on the hose barb ends to allow the use of screw in metering tips:
Dultmeier seems to have the best prices on pressure-rated fittings. You may have to go to Zoro for the PVC 3-way and a couple other items, though.
So, I was afraid this was going to be an issue.
First test was an utter failure. Water spraying out of the draw tube. Apparently, 1/8” is just too big an orifice (at least for the design of this particular injector).
For those curious to know, I used this injector previously as a back-pressure orifice on the bypass side of my k5 injector. That’s why it was drilled out to 1/8”.
Basically, a two step xjet, with somewhat lower pressure, if possible. I don’t need the high draw ratio of an xjet for my application.
I need to find a way to adapt to the inlet of a standard injector, though.
I have a couple spare orifices, so I can experiment a bit with different size openings. I want to draw chem at the lowest possible pressure, using my housewash tips.
Edit: I guess I could accomplish all of this with my actual xjet, since I know it has standard threads on the inlet.
What I really want is something where everything is screwed together and fixed in place, so I don’t have to use both hands to switch from soap 1, to rinse, to soap 2, back to rinse.
So an actual 2 step gun is to much psi then @Infinity .
I’m understanding now man.
Dont wanna go blasting through windows and caulking etc,etc.
Why soap, rinse, soap rinse?
We soap, soap, rinse.
I figured the bleach + acid thing was a bad idea…
You rubber scrubbers don’t use bleach in your caustic soap mix, huh? 
Ha !! No sir we do not.
Ok I’m still confused on what you are planning on using it on and also how are you going to carry 2 bucks and the gun at the same time. Also what are you going to use it on.
Are you referring to me?
I’m using it on the job discussed here:
Buckets go up in the lift with me.
