Best unloader
Bought this bcs I thought I needed it, and now that I have it installed, I'm buying another. NO MORE BOOMS! Let off r trigger and pull it again, calmness, only high pressure to the gun, I can adjust the pressure too. It came in a cheap bubble bag, and it had some small scratches, but I'm idc it's so worth it. I was blowing up hoses, equipment, hate that pressure that builds Everytime I let off. What a relief. I wasn't sure because I have it on a smaller pump I've seen them on some of the bigger pumps a 4 gallon per minute system 4000 psi this thing works great on I just spent 95$ on a name brand unloader that went with the pump and if I could I would send it back but I will be putting one of these on my other pump. 100% GO AHEAD AND BUY IT. IT'S WORTH THE 45-50$

I do not recommend this unload valve
This is a pulsating unloader valve, so it makes the pump vibrate while using it which ultimately damages the pressure washer pump because the wrapper changes in pressure continues after looking at the description. It says nothing about this valve pulsing. Not only does the pulsating damage the power washing pump, but my power washer is bolted to a pallet, and this pulsating eventually loosened up the bolts enough to where my power washer pump almost fell off the back of the truck. I do not recommend this valve for anyone unless you’re just looking to damage your equipment.

Good product but hard to get new seals for it
Bought this unloader valve last year and used it on 5 jobs. Unfortunately it didn't work on last job. Today I have disassembled it and found out the a few seals are bad. Looks like it's hard to get new seals. I've looked on Amazon and ebay, no luck so far.
