It can be done from what I’ve heard…just not worth the effort in my book. In our case they’re like $12, so as long as we can remove the QCs to swap onto a new one (and we always keep a pre-built with QCs on every truck to keep from losing production) then I consider them somewhat disposable. If I can get 2 weeks out of them, the math puts that at 0.06% of revenue…I can afford that, lol

You’re one of my favorite dudes in this here forum by a longshot! (props dewd!) But you’re clearly looking at my question from an operational standpoint & not from an engineering standpoint, which I totally respect. But you don’t break ground sticking to what works. I’ve placed the order & I’m going to give it a stab. Wish me luck! In the meantime, I’d love to hear how this contraption worked out for @Racer in the meantime.
Aww, that’s sweet 
This should surprise no one…since I’ve been an accounting & finance/profitability guy since college. There weren’t any chicks (at least any that looked like chicks) in the engineering building back then…my decision matrices were a bit different back then, lol. My only engineering interests fall somewhere between MacGyver, and “because I can”…
They went out just as quick as the cheap ones. I’ve got 2 new ones in my spares box and I’ve just been running the standard. It pulled maybe 10% better. I average about 125 hours out of a standard one, but I’m pretty good about flushing it at EOD. Like Jason said, they’re chump change. Works out to .12/hour.

Good to hear from you sir! I’ve found that DS injectors can grow old just sitting in the tool box with zero hours of use and become lazy or even useless altogether. If I find a better way, I’ll send you a present, hopefully it will have a better draw rate as a bonus. Hope you are doing well.
Physics doesn’t care about either of our opinions. If we stuck to what works 20 years ago without room for debate, your employees would still be climbing ladders to red tip that vinyl siding. Somebody had to push the envelope / explore new ideas. Or maybe you’d be a cosmetology specialist by now (lots of chicks!).
No they don’t, just ask IBS. He’s got buckets of them. Spend your time doing something constructive to build your business. Then you won’t care about them.
I’m fine, thanks for asking.

I appreciate the advice dude!
Is this not the best way to do it? At least the red tip definitely gets the 12.5% off there, it’s sometimes stubborn once the hour dwell time elapses…
Might have entertained that back then…but I’m a bit older, wiser, and have a better perspective these days. lol
I used the modified injectors with the check valve. They didn’t last 2 weeks. I bought all the fittings to build them myself. What a waste.

Hahaaa! Red tips are for cutting firewood. All jokes aside, I have competitors around here that prop ladders up against one story vinyl houses. That way they can get 2 inches away from it take care of business!
Gotta get that artillery fungus off…

I think I may have read that somewhere…that was a good book

If I was more savvy and had access to machinist tools I would develop an injector ‘booster’ that guarantees 1-2% through the pressure hose regardless of gpm.
I may try a larger diameter hose like @Innocentbystander suggested. Right now it’s a dip tube from the vert tank, up to the valve then down to the injector, all with 1/4".

I really like this setup - SH tank on one side, water tank on the other. I have 3 ball valves so I can DS straight SH, straight water (to rinse the injector), turn everything off or anything in between. I’ve considered adding a poly / viton check valve for a while now to prevent SH from back siphoning into my water tank (it does). I’ve got a couple on the way. First thing I want to try is running an injector with no ball or spring to see what happens. I’ve got nothing to lose.
yeah, had a big siphon of SH into a 275 gal tote this summer…which reminds me that I was planning to vent the water tank lids this off-season (which after finally getting done with Christmas lights, essentially starts today, lol)
That means it’s going through the pump in your case. Do you run a similar setup using the buffer tank to supply water to your injectors?
Hadn’t really thought about it. The trucks are something I have to pretty much look at to understand still (or at least our schematic diagrams of them worst case). We were so busy draining the buffer and flushing everything through after that, I didn’t give it a ton more thought once we alleviated the problem.
It wouldn’t have gone through the PW at all (well, other than what was pumping out of the buffer). We had some bad parts and not closed valves in the proportioner possibly. My service manager handled most of it, I just found the temporary solution to pop the little cap out of the lid to vent. I want to do something better to keep it from geting bugs and crap in the tank though.
Don’t stand on front of it, you’re gonna get wet. One three way ball valve would be a lot simpler. Send me your address and I’ll send you one
