Connecting Two Pressure Washers Together

Nigel, Thanks for sharing, your YouTube video was helpful and inspirational to me when building my rig. I've been using the double motor/pump set-up for over a year now and it really is great.

Russ, there are times when I close a ball valve to bypass one of the machines for a stronger down streaming mix, for some situations (It is a lot better than having to break out the x-jet in my opinion). Do you sell or know where to find, a high pressure ball valve that can be controlled electronically. I would like to set up a remote control if possible.
 
Richard,
That depends on your nozzle size. A trigger gun that is sized for your 4gpm machine will create enough pressure to shut off your down streamer, and too small of nozzles or different volumes of h2o will put one or both machines in bypass. It has taken a lot of research and practice to get mine to act like a professional high volume machine. GPM x2 not pressure.

Glad it was of help, remote sounds nice, two other options popped into my head on ways to do this but it would depend on the machines you currently have

It would be double GPM, but not double pressure.

Why couldn't you just shut of the engines down? Would that not work?

Yes, just less efficiantly. I might wash some concrete and want to kill some sporse after or have some other kind of tough spots that just need a little extra. that way I'm only using the strong mix where it's really needed. If the entire project needs stronger mix I just swap my injector for a smaller one. Something like bad stucko I apply chem with one and rinse with two.
 
My chemical injectors don't work if there's back pressure So they wouldn't work before the T. The higher the flow Of soap the smaller the diameter of the hole in a downstream injector. The 2.1mm is perfect for most applications. The 1.8mm works for Higher concentration If I still want full flow from both machines. The problem with the 1.8 is it creates more back pressure on the system from that tiny little hole And disrupts the flow for my service cleaner. Do you know of a different type of injector?
 
Have you thought about getting a clutch for one of the pumps and have it wired to a remote control?

This way you can just disengage one of the pumps from the flow temporarily and then engage it when done downstreaming.

You can also setup the soap hose with a solenoid valve to the same remote control system to shutoff the soap.

Just some different ideas.

Just the adjustable orifice super suds sucker and the double injector. Would a 12 volt chemical induction system help.

Disrupts the flow to your "surface cleaner" you meant to say.

Right on Chris, thats why I asked what type of machines, if is a belt drive, a clutch with remote on off, if is direct drive or gear box, Greg would need an electric start motor, then he could remote start the motor.

He could also remote start a chemical induction system

I don't know the first thing about a clutch. It really isn't that hard to turn the valve. I've just needed a stronger mix on wood which is often in the back yard deck or dock.
Here is a picture; the ball valve is on the right. I pieced the trailer and washer together mainly from parts off craigs list. several different motors pullies and pumps carts, mounted on a hot water skid frame.

They are set up to put out 4.5 gpm when ran individually through a hose reel and injector and 200' of hose, and put out about 7.5 when ran together. That number seems to goes up when I pull the injector and or bypass the hose reel. I think the back pressure just slows those little motors a bit. No real issues in months. I spent some time scratching my head until I discovered that one of the motors from c's list was actually an 11 hp that someone put a 13 hp pull start on.
I am curious about the chemical induction system you mentioned, in theory but it's not really an issue.
 
You can if both machines have trap pressure unloaders without the easy start built in.
