UNLOADERS PART 1: How to Set an Unloader 

Awesome video coming from a Pressure/Softwasher! Subbed

Great quality video! Super informative! And exactly what I was looking for, keep it up!

Great explanation! Thanks

Thank you for this very informative video. We have a Simpson 4400 psi pressure washer that has a built in (part of the pump) unloader. As far as I can tell it does not have a bypass like the machine you show in your video. It only has a pressure relief valve and then a small (possibly) another relief valve on the bottom of the unloader. There does not appear to be any extra inlets of outlets to install a bypass hose to. Would we have to install a secondary unloader in order to install a bypass hose to run out on the ground or recapture in a tank?

Thanks for sharing, great information. Could you please let me know any idea how to bypass my Predrator 4400psi, 4gpm?

Is the ball bearing that is on the end of the unloader needle supposed to come out?

Very nice tut, How to choose the right unloader and where i can buy ?

What does it mean when it suddenly kicks into bypass while pulling the trigger.. it will be fine than randomly just stop the pressure.. just cleaned the valves so dont think it then, changed the bearings botg roller and ball..and changed oil..

I can't seem to find this unloader on your website to buy, is this discontinued?

I have my handle zipped tie open and i tie it down when i start it at low speed It’s 12/13 years old and no problem at all

Good Explanation but what about these Ryobi pressure washer 3000s with Honda GCV160 engines and runs great with trigger on wand fully depressed but surges when idle. How do I set my unloader valve on it

Thanks for sharing, great information. Could you please let me know how can I bypass my Predator 4400 psi 4gpm?

Why is my pressure washer building pressure while I’m trying to crank it. I have to hold the trigger for it to come on

Could anyone tell me how to spot the difference between a trap pressure unloader and flow? I've looked at mine and cannot tell.

This video should be titled "How an unloader works" not "How to set one"

Now see this is confusing to me pretty sure my machine needs a new unloader valve and whats bad it's a brand new machine. I've already contacted the manufacturer and they're sending me a new one. Now my confusion is somebody clarify this for me my machine is rated for 3600 PSI with a 0° red nozzle or a turbo nozzle on my wand when I pull the trigger on the gun im barely getting 2200 psi but when I let go thr head pressure jumps all the way to 4200 psi and then settles at around 4000. Funny thing is adjusting the unloader does nothing for the pressure but when I tighten it down the head pressure increases instead of the outbound pressure including where it settles for example tightening it almost all the way down at the manufacturer's full stop idle head pressure jumps all the way to 5000 psi and then settles at around 4800 psi and the engine definitely does not like it because it's strains like crazy to get it there but what's weird is when I pull the trigger no matter where the unloaders is set on the gun pressure drops all the way to 2200psi or lower depending on what nozzle im using like the 40° nozzle when it's installed pressure barely goes to 1200 psi and then skyrockets to 4000 psi as soon as i let go of the trigger. Surely that is a sign of a failed or malfunctioning unloader valve?

I have a Dewalt direct drive I believe 4000 psi 3.5 or 4 gph. Can I make it discharge to the ground or a tank?
