Found this on Facebook. What do you guys think? In theory it’s a great idea imo.
What even is it supposed to do? Increase draw rate?

Looks to be 4 injectors? I’ve heard of this recently. I’m also curious about it
By splitting the water flow each injector should pull a higher rate. 8gpm/2 = 4gpm witch should in theory have a higher draw rate then 8. Add in the dual injection possibly increases the rate. I don’t know, so I’m curious.
It’s two dual injectors.

I think it’s a hot mess! 
Unless this lets you pull a hot enough mix to clean stucco or a roof while downstreaming then I don’t see the point.

Seems a little dumb. What’s wrong with one injector pulling SH. I don’t get why people try to reinvent the wheel. If you need a higher concentration of chemical build a 12v system.

I’ve been force feeding my injector to post treat concrete. It eliminates the need to pull out a second hose, it eliminates having to flush the second hose, it elongated the need to reel the second hose. There’s nothing wrong with reinventing the wheel if it improves productivity/
Thanks @florida_condo_cleani for the suggestion

I post treat downstreaming straight SH it works fine. Look, I’m not trying to tell people to not be creative.
In my opinion the simpler the better, the less moving parts, the less to break. The less breaking creates less downtime which, in return, improves productivity.
But whatever, to each their own. I don’t really care how other people wash houses. If I find something that works better I will share.
If this new creation can somehow cut washing time by 10-20%, I will be buying one. If not it was just a fun little weekend project for the dude who made it.
Now, I know I’m rambling. I love creativity and I think when groups of people use their brains to work out problems lots of good things are created.

If it does work for roofs don’t tell any one on here, shoot me a message lol

I’m following the post. Apparently a few have done it before. They’re saying it can get you a 30% mix but you’re limited to 125’ of hose. That’s a deal breaker for me. I think dual force feeding would get it hot enough for a roof throttled down but that’s purely a theory.

Not to mention what it would do to your expensive pressure hose and fittings.

Nah would maybe only shorten the life slighty if any.

Will a single dual port injector pull equal amounts of HW mix from one tank and a marker indicator from another? would i need to put a metering valve on the indicator so it doesnt pull too much (or dilute too much with water)? looking to add a color pattern to my DS set up, cant afford a dedicated softwash system yet.
I’ve read of people successfully downstreaming apple wash via dual injectors and metering the soap. No idea of the details tho. Can’t find the time to pursue all these sweet ideas I read about
I wish I had a few days that I could use to just fiddle around with all the stuff I’ve been meaning to try.
I got a bunch of cool toys for my new wfp, and just started trying them out on the job today. I’m liking that bronze wool pad holder for initial cleans.
One of my hairbrained ideas partly inspired by this thread:
Find/modify an unloader to bypass at around 150-200 psi.
Run a 3 way valve off my pressure washer so I can choose between the high pressure or low pressure unloader
The low pressure side would be for high-concentration chem app.
I would run one of the dual twin injector setups pictured above, and force feed it with maybe a 4gpm 12v pump.
All of that would run to 1/2” or 5/8” flexzilla. Thus the need for a low pressure bypass.
My idea is that this would provide a better flow rate and stream distance than a typical 5.5 or 7 gpm 12v, for the same or less money.
The downside of course is that you’d still be limited in application strength. But I would be very surprised if it wasn’t strong enough to clean just about any roof or similar surface.
The strength of the mix could be metered by throttling either:
- the 12v pump with a PWM (reducing the concentration, and also using less power)
Or: - the machine (increasing the concentration, but likely losing some spray distance (smaller nozzles might help a little))
@sgb Says the guy who has no idea what he’s going to clean with it or what chems would be run through it. You know we don’t all clean the same things right??? Just wanted to shed some light on the fact he may be cleaning carpets with it or something. Don’t live in a bubble man! I clean fleet vehicles and heavy equipment btw
I would have no use for it or anything similar but I have electrical mechanical components on my rig that would blow your mind. You know reinventing the wheel and stuff. I use the pumps vacuum to draw in a concentrated alkaline soap so I can apply soap using high pressure. I then control the soap using only the trigger. No remote like that box that’s being sold on here.
