    • A great accessory for your pressure washer
Style: Short Gun
Shipped quickly and packaged well. The compact design is exactly what I was looking for to use with my foam cannon while washing my car as well as by itself for rinsing it. A great product and very good value.

    • Great for Rinsing

Works great for rinsing. Bolt on top loosens if not careful. Lightweight and great entry-level ball valve.

    • Now I've got options
Style: Ball Valve
Perfect for switching between my surface cleaner and my wand without having to turn my machine off. I’m also able to take it off my surface cleaner and use the valve without an attachment and get some pressure to rinse driveways clean between sections so I don’t get too much dirt buildup in front of me. ... show more

    • Works great but dangerous.
Style: Ball Valve
I love being able to swap guns without shutting off the pressure washer. I’d highly suggest adding a 2 foot chunk of hose after the valve, especially if you’re running a big boy pressure washer. When opening and closing the valve, there’s a moment (when the ball valve is just cracked open) when extremely high pressure water blasts out of the valve and could easily lead to a hydraulic injection injury, (not something you wanna look at pictures of) which are incredibly life threatening. Add a chunk of hose after this valve so that you have a buffer zone between you and the highest pressure water directly after the valve. I’m running a 5000psi pressure washer which will easily slice an arm or hand open if you get too close. The other option is to put this valve on the pressure washer side of the hose vs the wand side. I wanted it on the wand side so I’m not constantly walking back and forth. ... show more
