I’ve had an AR45 system for 2 years. Taking delivery tomorrow of a dual Remco system. Give me a week and I’ll let you know if you should move to gas.

I love the quietness of my 12v. My wife laughs at me because I like to hear the outdoors when roof washing. Same goes with the 24v, but it seems like I waste a lot of chem.
I can tell you now, you’ll waste a lot more with a gas setup. I got mine mainly for industrial buildings and real high, long range peaks on roofs, because of head loss with a 12V above 30ft. But it’s kind of a PITA to use compared to just a 12V for routine stuff or something simple like post treatment or touching up a foundation or something. I rarely use it. Maybe 10-12 times per year.
I’m hoping this dual !2 will be a good happy medium. Got 7-8 roofs to do in next couple of weeks, so guess I’ll find out. The good thing about it is if I just need one pump it’ll still work like normal. Main advantage of the gas pump is not ever having to worry about battery life so on big projects that’s a plus, but since most the time I’ve got my machine running anyway and have it’s battery connected to my others, it keeps them charged 95% of the time. I very rarely have to hook up charger.

I plumbed two Delavan 7gpm pumps together with check valves. I know I still have an air leak somewhere (pumps don’t stop running - eg never reach pressure) but, it saved my bacon last week. I was using just one of the pumps (small 2k SF roof) and needed just another 15’ of distance to reach the peak. I turned the second pump on and was able to shoot over the ridge. I was getting at least 45’ and I’ve got a leak. I have 200’ of 5/8” hose, 2x Delavan 7gpm pumps, (would prefer Remco’s instead), and pull from the top of a 335 gal tote to a 3-valve 3/4” Proportioner/mixing block.

Did you buy the two gpm 12v pumps from heath? I agree on the gas system for large jobs. We have some large stucco commercial buildings and roofs I hope to utilize it on. On a commercial apartment I tried the 24v and 12v. Speed wasn’t noticeable, but chemical usage was huge. I had a few tell me the gas system will wash a house a lot faster than downstreaming and I’d like to test that. The flow pro and 8gpm seems hard to beat.
You’ve definitely got something wrong. I get 40’ with a 5.5 NT pump and 250’ of 1/2". Send me some details pics and I’ll help you out.
They’re full of crap, lol. Unless house needed a 2% mix or something. They may be close, but I have both and have never even considered using the AR for house washing.

I agree with 2-7"s been looking into the 2-7’s or a pumptec x6
. I think the 10 gpm with 2 heads will not give you as much flow as 2-7’s One motor turning 2 heads…vs. 2 motors turning 2 heads.
I got my setup from the guy that lives about 20min from me who developed the control system for them and the X6. The X6 flow is about 6gpm, about same at the 2 combined at end of hose, the only difference is the X6 runs at higher pressure. The way we built my box, if I’m not happy with the dual 12v, I 've got room to swap out one for an x6, then have best of both worlds. But want to try this first. The X6 is expensive, but not a diaphragm pump
First off, get rid of the check valves, absolutely no need for them. What’s the model number on your pumps? Delavan makes a model that doesn’t have relay, so it runs constantly.
Make sure you prime your Proportioner. cut all the valves off, except the soap, turn it wide open, make sure it’s sucking thru your intake hose with no bubbles, then do same with SH line, then water. Doing this, it’ll let you see that everything is good to the proportioner or not and where your leak is coming from. Soap, once it’s primed will usually stay. But I always run my SH just by itself to check it, you’ll see in 10 sec whether you have an air leak anywhere

Rick, do you happen to have a pic or diagram of the dual 7gpm’s, and are you running two batteries?
Maybe I’ll just do that instead of the $$$ 24v. Price increased to $230 but still half the price.
Is that a tankless water heater on your cabin??? Really roughing it out there lol
It is
A warm shower on a cold night in winter under the stars is a great thing

If you’re going to run dual units, need the 2 batteries. I’m running dual 27’s and going to hook in my machine battery to keep them charged, but we built in a charger with external port anyway. He rec the 29’s but couldn’t find around here and it’s not that much difference in performance. Lot’s of weekend work for me this weekend. Have to re-plumb everything for the higher flow. Here’s one I got, except because I already had box and because of way truck is, everything reversed and my blend manifold outside of box. I’ll take some pics when I get it finished. The secret to his is that control module and the modification he makes to pumps so you can run different size nozzles w/o the pumps cycling. His background is in robotics, so he’s good at this stuff. The pumps never cycle one you get it adjusted. When I tested it when I picked up the other day, was putting out right at 9gpm thru a 50’ 5/8. Going to use a few times with my 1/2" to see how it does with it distance wise.

Holy smokes, that’s a lot of flow in that video. Probably more than my machine. 
Thanks for the video, I’ll have to consider my options now.
BTW what hose is he using, looks a lot more flexible than my Ag hose.
I need that gun.
It’s just some old black pos 5/8 he had laying around. It’s not bad though, used it the other day. I’ll ask him. He doesn’t think much of Flexilla for softwash hose.
He’s got a new one now that’s about $200 lol. The problem with all of those type guns is none of them make a flat spray. I’ve been using my 7-12 M5ds nozzle on my regular old softwash gun on roofs lately with my AR45 and it’s working great. Easy to adjust your pattern when doing roofs.
Anyone use a Suttner 2315? I have a spare, thought about using it.
