Roof system for stronger mix for most.

The psi won’t matter much with actually washing houses. Most of your tips are gonna be below 300psi. But you still need to know and understand how to read a nozzle chart so that you can really dial in your system. My JROD setup is ideal for my system but you may like something a bit different. You can buy a dozen different tips and test them out to see what you like best or you can learn the chart and narrow down your search to 3-4 tips and save money.
And, yes, for those substrates you’re going to want a direct application method as @TexasPressureWashing suggested. Vinyl cleans up great with .75% to 1%. Stucco may take 4% to get clean and no downstream injector is going to produce that regardless of what envirospec claims lol

So I’m wasting my time downstreaming these houses? Soft washing a house 4% is a little freaky considering landscaping.
No. There’s a lot you can downstream and get clean. I’ve cleaned some light staining on stucco downstreaming with my 8gpm and I’ve had stuff that took 4% on the really bad parts. Anything hotter than HW mix and I’m watering everything around the area before, during and after rinsing. You can mix up a couple different pump sprayers with different mixes and do some test spots to see what’s going to work best for that job. Shoot for a 7-10 minute dwell.
Good lord, this man would not take my money

But I can try!
Nope.
Get a 1/2’ banjo on-off valve and then put a 1/2" to male GHT on end of softwash hose. Then can use any kind of nozzle you want.

Wow. Can’t believe all the back and forth about JRODs ability to soap/stop soap siphoning.
Admittedly, I may lack the decades of experience that some on here possess. However, I know what works for me.
I use a JROD (Pressuretek) exclusively when I softwash houses and rinse surfaces. What I know is there are two tips that soap - low and high, and two tips that spray - low and high. The “low” tips fan either water or soap, and the “high” tips stream either water or soap. The only pressure I would be concerned about using on someone’s house is the high rinse tip, up very close.
I soap with the low tip (if it will reach what I’m cleaning) and then rinse with low water tip. Perfectly safe. I repeat, perfectly safe. As a matter of fact, I have 2 jRODS setup for 8 gpm, one on my short gun, and one on my long so I don’t have to keep switching JRODS back and forth, I can just switch gins as the application calls for it (commercial work).
This setup works, pulls chem when it’s supposed to, rinses safely and effectively when it’s supposed to.

I’ll add, I am using hotwater, and when I am on my low rinse tip with the JROD setup (short gun), I can hold my hand 8” from the tip safely. Tell me that’s too much pressure to wash a surface.
The Jrod that you use from pressuretek on the 8gpm pressure washer for downstreaming, do you also use the same one/tips on your 12v softwash gun?
I use a 4 gpm JROD tip setup on my 12v rig. I based this on my pump that puts out 5.5 gpm, and, I already had a 4 gpm JROD setup on hand. I mix my batches 50/50, usually (12.5SH/Water)
Of course, since this is a straight pump setup (no siphoning) each tip will push chem through, but I made my JROD a 3 prong setup - low volume fan, high volume fan, high volume stream.
Don’t use two guns. One gun should run everything you own. Yes, a low rinse tip should be able to spray your hand. That’s the point. All of your tips should be low pressure. But, of your low rinse tip is soft enough to spray on your hand, it’s still pulling soap.
I do use the short gun for about 90% of operations, along with surface cleaner. The long gun comes in handy for edging raised sidewalks, and for cleaning areas with poor drainage, so I can’t abandon completely. Also, when you need that extra reach to hit the 2nd story gutter with chem/rinse, it comes in handy for that. Short gun delivers almost all soap, and rinses everything for me. Also, extremely effective at rinsing sc work, and moving stagnant water from a holding spot.
I use a j-rod, didn’t like the m5. Too much overspray. You’ll change out at least two of the tips on the j-rod (because you’ll eventually want a shooter tip too).
I also use the same j-rod with my 5.5 12v when I’m “soaping” a roof, but I pop it off and put in a loose 2515 tip when I want to mist on a concrete pre/post.
Use a quick connect on you gun and you can plug in a short wand, long wand surface cleaner etc. To change guns you either have to turn off the machine or use a ball valve, and both are bad options
