Found the guy on ebay…cost…wait for it…$400.00. Custom built to my specs. Holds 20 gals.
You can use a Marine type plastic tank that will work just as good and a whole lot cheaper. I just got a little carried away when I built this one.
But Sure Looks Good Going Down The Road!!! LOL!
All of our machines are 8 gpm and we use 3/8’s hose with no problems at all. Though I’m no expert I’d say if you exceed 9 gpm you might want to move to 1/2" hose. But I sure don’t want to have to drag 1/2" hose all day or buy it.
Guy what ds injector do you use that was my biggest problem once i went to 8.5 gpm i couldn’t get any injector to work with 300 ft of 3/8 hose a sud sucker worked a little but not great. 1/2 hose fixed the problem
We use general Hi-Draws rated for 3-5 gpm . We run 200’ hose hose.
When guys switch to 8 + gpm machines they usually make the mistake of matching machine gpm to injector gpm, and if you’re using over 100" of pressure-hose a matched injector won’t work. There’s just enough “Back Pressure” or restriction to stop the injector from pulling. Dropping down to a lower gpm injector will solve this problem, and pulls like crazy.
I use the same as Guy. Works great.
How much difference was it?? I am going to hook up my 2 8.5gpms together… And let the other 2 8.5 gpms for washing down…
If you are going to run 2 8 gpm machines together you will have to use all 1/2" hose the 3/8" will restrict the flow
Now you tell me lol doh…

What does that do to your GPMs?
I run 2 8.5gpm machines on my main rig. We usually like to tackle large driveways and concrete by running 2 machines and surface cleaners at the same time… Which is about 17gpm… I use a 275gal tote tank as the buffer, and always start with it full. I frequently run it empty while running two machines, unless I double feed it with two hoses from two different spigots.
.
In theory 8gpm through 3/8 hose will cost you 300psi per 100 ft so a 300 ft section of hose losses 900 psi by the time it hits the nozzle. Were 1/2 hose looses 35 psi per 100 ft so the difference is huge at that volume and it feels like it. For me i really dont need that much psi since i dont do much flat work i only switch because of my injector issues
Good question Thad…I have no idea really. I see no “real” problem when we’re washing houses or apartments but I do see a difference when cleaning concrete. That’s why all of our set ups have QC’ed down streamers at the reel. Just takes seconds to pop them in or out depending on the situation.
All I do is flat work … I was just wondering how much it would help … If its worth it… My time is limited I need to get done faster…
Rodney, if all (Or just about all) you do is concrete cleaning then I would look into switching to 1/2" hose, especially if you’re going to run above 10 gpm. Make sure your hose reels are 1/2" also, some have 3/8’s manifolds. You’ll also have to modify your surface cleaners with regards to bypassing gun (1/2" Ball-valve) and 1/2" hose to swivel
The speed will be awesome and there are several videos on youtube showing high flow surface cleaning, it’s crazy fast…Just remember you’re gonna need a “High Flow Supply” to your tank or tanks.
i thought i went big when i bought my 8gpm… guess i still am a little guy;)
Thanks guy yea I am going to swap over … I clean a lot of truck stops . Got a lot of parking lots to do also… I am going to build a new rig box truck with a 1500 water tank. Or something got to figure it out…
