To see how much gpm you are losing, just look at your bypass hose in the tank. I lose at least 3 gpm because I am using a smaller injector on my 10 gpm machine. I wouldn’t want to lose ANY flow on my machine. Why buy a 10 gpm machine when the injector robs you of 3 gpm, and there is a way to stop the robbery!
So I’m thinking maybe I need one of these bypass systems. I guess they’re definitely worth the $$?
Absolutely!
So, has anyone configured their bypass so that the injector is on the bypass side, and the ball valve on the “straight-through” side? Essentially the opposite of how Bob’s kit is set up? Would it be worth it for me to switch things around?
I first stumbled on the recommendation from this site: https://www.pressurewasherproducts.com/pressure-washer-plumbing.html
I haven’t heard of anyone setting it up that way, bit it seems to make sense to me.
Alex, here is picture like you’re talking about. I agree. Had friend who actually tested back to back and the bypass like everyone sells knocks about 150psi off. Sometimes I just leave mine in but I run an injector sized for 3-5 gpm even on my 8.5. Knocks it down on flow to 7.5gpm. So unless I’m doing concrete, most the time I’ll just leave it on.

Hey just got my bypass today… so in that pic is that the best way to set it up? Or should the downstreamer go in the middle?
Unless you got Russ to make it up like this, may not have all the parts. When I ordered mine I sent pic with specs, ie all stainless where possible
Does that go right to your hose reel or a block?

Hi there Racer…first off thanks for all the great advice you have posted within this community. As someone starting out in the business it has helped so much. I have a 8gpm unit. I see you’re using a 3.5gpm injector…you find it pulls chemical better that way? Thanks in advance.
yes the 2.1 for 3-5 gpm machines

My question is when you have the bypass kit install do you still have to switch the chemical injector hose from wash to rinse when the valve is open won’t it still pull chemical with water if you leave the hose in the chemical tank all the time?

Not that I’ve ever noticed
Thanks just trying to figure out how it works…
No. The water will take the path of least resistance. So even though the water COULD go through the injector, it will go through the much larger orifice, which is through the valve and its associated fittings, putting the injector “out of play” until you close the valve, FORCING the water to go through the injector.
