Na the most wear is on the orfice. Some run 2.1 orfice to get more draw and water there sh down. But I like using a 2.3 orfice and straight sh about .85 percent hitting the surface. U get more gpm for rinsing and ur sh will last a lot longer than being water down. And no wasted room in tanksš

Maybe itās in my head but when I close my ball valve partially it seems to put out less water volume and psi this creating a stronger mix when using the xjet.
@Coolunderpressure your correct on the machine. I believe we have the same skid.
Harold instead of closing ur ball valve some. Install a 2.1 orfice injector then u will be getting 7.5 gpm and ur xjet will put out a stronger mix. But it will be consistent instead of closing the ball valve some. And the xjet has an orfice to so it will affect the stream coming out. Kinda like using a xjet rated for 8 gpm with a 5 gpm pump. It wonāt affect the stream munch though just wonāt shoot as high maybe bout 5 feet.
Makes sense. Iāll try that. 
But to answer your question. Yes if u close the ball valve off some and it is bypassing say 1 or 2 gpm. Then ur xjet will be putting out a stronger mix. But I would suggest if u had a 12 volt or air diaphragm use it if u need a mix that strong. Or install the injector with the 2.1 mm so at least it is consistent.

I do if the job is big enough. My 12v mix tank usually has 50/50 40/60 ish. The xjet is in the middle for me. DS, xjet, 12v. Weakest to strongest. I should get a porportioner
When I went from 5 gpm to 8.5 I changed the orfices in my xjet. Couple of bucks if Iām not mistaken 8 gpm takes number 14 orfice in the xjet I think. Easy to change donāt take but a minute. They just slide in they donāt screw in like the one on ur injector. Just donāt drop the spring!!
I changed it. 8gpm calls for a 16 orifice.
But I found that the 13 orifice, which is for 5gpm puts out a stronger mix. So I kept it undersized to 13.
Got ya. Just bypassing a good bit of water. So once u get through applying you remove the xjet so u have 8.5 gpm to rinse with. Iām firing up my air diaphragm pump Iām not a fan of xjet carrying around a bucket. But I do have one if the situation arises. But I havenāt used it since I changed the orfice in it.

I might use it more if I had a air setup. I donāt get the range that I would like with my 5gpm 12v. It does the trick for roofs. A new setup is on my want list. Didnāt make the need cut just yet.
