Exactly instead of paying 100 bucks for a gun pay 100 bucks for a k7 u can use all ur guns with:grinning:

Interesting thread. If you do a lot of wood the one “disadvantage” of the pressure trapped unloader is you have to remember to point the wand away from the wood when pulling the trigger. That trapped pressure can impact the wood much harder than it will when the pressure is normalized. It can change the finished look on the board if you’re not paying attention. Not a big deal once you learn it but it was when I started training new guys…

I’ve been running flow unloaders including K7 for years. I’ve run them of 50’ up to 350’ of hose with no problems. I have used them with buffer tanks and without. Only issue was k7 is limited to 3,500 psi. So I bought a different flow unloader. With flow unloaders there us less wear and tear on your equipment and i never have to worry about my employee shooting a tip through a window or onto a roof because it wasn’t seated in the wand correctly.

New rig will be in tomorrow. Glad to see all the comments saying it works with ds. I also have some 3/8 hose on the way. I’ll let you all know. I’m thinking they are pretty darn popular not to be able to ds

I got the 2315 mainly for it’s chemical resistance. But when I was still running the trapped pressure unloader, it was nice to be able to slowly squeeze the trigger to avoid the kickback when it would be a problem in a tight area.
But personally, I found it easier to just “caveman it” most of the time. The slow squeeze took a lot of muscle control for me, and as soon as I would get a little kick, my hand would clamp shut and I had the full kick, lol.
My K5 is treating me well, so far. No issues with DS on 200’. I can’t imagine why longer lengths would be any different, honestly.
I have heard that the flow unloaders can get finicky if you get air in the line. So maybe the guys who have had trouble, were the ones who will just pull the soap tube out of their mix tank and let it suck air?
Another theory I have, is that sometimes the check ball tends to stick inside the injector, and without that sudden kick of pressure, the ball won’t dislodge itself as easily.

Why is everyone’s videos in reverse? Or are you in Europe?

About half of Rob Anderson’s videos are reversed. I think it has to do with how it is uploaded or an app that is used?
Most “live” videos, like fb and youtube, reverse the image to make it a mirror image to the person on screen. Seeing a non-mirror image can be a little distracting for many people. Like when you walk into a grocery store, and there’s a CCTV monitor on the ceiling, and you’re like, “that looks like me, but I’m going the wrong way!”

Anyone using a zeromatic unloader? I’ve been looking at replacing the stock one (vrt3?) with a good one. It’s a pressure unloader but doesn’t seem to have the same kick as other pressure unloader based on what I’ve read and video from Michael Kreisler.

800 psi AG hose is well suited for the bypass line. I’ve never popped one. I’m not sure if cheap poly braided hose will last long. I use AG hose for just about everything from plumbing the roof pumps to bypass wire insulation. The stuff is really tough. I buy a 100 ft roll of 1/2 every few years just to have around
Poly braid will last 7 or 8 years before it gets pin holes
That’s a lot longer than I would of assumed
I was engraving serial numbers on two motors this weekend and realized it was the third motor on one skid. Plumbing is still original do I figured it had to be at least that old
@squidskc I’m sorry, I don’t know for sure, but I think they do, I was looking for this for some time, and I thought maybe it might help someone a bit, see what PA says for it in their Pulsar Zero flow sensitive unloader Technical Manual, especially DISCHARGE SYSTEM AND WATER ADDUCTION part:

That was incredibly informative and detailed, thanks for sharing that.
What I got from it, is you can use a variety of methods to increase the back pressure on the bypass line, as long as you get it up above 60-70 psi or so.
What I’m thinking of doing is using an old DS injector, drilling out the orifice to 1/8” (equates to a #25 nozzle, and would produce ~250 psi @ 5.5 gpm), and install that between the unloader and bypass line.
Then I can run whatever size hose I want, 1” if I like, and reduce the turbulence/force of the water going back to the tank.
