Connecting Two Pressure Washers Together

I have searched and searched with no luck on this subject. I am interested in doing this with a couple of cold water units we have had in storage forever. They are both 3800 psi @ 4 GPM. Does anyone have pictures of your setup, any complications?




Also....with this setup in mind....how would auxillary tanks work on these little cold water units, would it need a fuel pump?

Thanks
 
I do have a kit to hook them together. It's 2 - 4' jumper hoses, a 3/8" hydraulic tee, 2 stainless check valves, 2 hydraulic nipples, and couplers for easy on / off. For Honda 13 hp engines, you'll need regulators on the fuel pumps, too. The float closing pressure is very light, and a fuel pump will just shove it open, flooding your engine with gas.
 
Hey Mike we do it all the time. Those two cold water Pw's u see on the side of my flatbed are over 10 yrs old. The engines and pumps have been fixed or replace. We beat those machines to death. Use them on almost all residential wood restoration and house wash jobs. If you look closely at this picture with the flatbed you will see those two small machines are hooked together with that Tee that will not let the water shoot back down either one and into the pump. Those tee's are not cheap and but you need them so you don't kill your pumps etc. Russ had a good deal above. Ours are connected with two jumper hoses into the tee and one hose out. Sometimes we run that out hose into the burner so we have Hot water too. In this case those two machines are rated at 3.5 gpm @3000psi so they were used for rinsing @ 7gpm @3000 psi.

Alrighty.....I sent the Little Blue Two Pumper out this morning on a commercial run and here is the feedback I got from the tech. When both units are running and the water tank is full, the surface cleaner is running slow.....I am guessing it is starved for water. What diameter hose should be feeding the two machines from the tank? I have two garden hoses connected to a splitter (See picture) being fed from the tank, through a filter by a 5/8" or maybe 3/4" hose.

You're going to kill both your pumps with that inlet setup. Each machine should have it's own feed from the tank, or at least a large diameter (1 1/2" or better) splitter right on the tank. Garden hose makes horrible suction hose...it collapses too easily especially when warmed by the sun. Inner braid or the stiff coil wound hose is a much better bet, at least 3/4", and as short and direct as possible. Lose the bolt on unloaders. Go to a separate unloader / inlet setup, and bring the water straight into the side of the pump without any elbows.

Direct drive pumps have a hard enough time drawing water without making life tougher on them.
 
Mike, I run that setup with 2 4gpm belt drives and both have a separate 1 inch supply line and separate filters from the tank
 
Charlie and Russ....thanks for the Great Info. What would you recommend for unlaoders on these two machines Russ? Also....should I change the tips on the surface cleaner? Need to find a bigger splitter and buy some bigger hose.
