  • Leaks from the handle
Poor quality. Leaks from the handle well under its alleged pressure rating.

  • Works great but dangerous.
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

  • Basically a high pressure complete shutoff ball valve...
Got this so I can cut off my pressure washer's pressure when I switch from my foam cannon to my washing wand and it works perfectly. Much easier (and less messy) to completely cut off the high pressure water flow and not have to fiddle with pressurized connections and get wet. Just remember to not leave it closed for a long time as your pressure washer pump will overheat and fail. Normal ball valves don't have the pressure ratings to withstand the high pressure your pressure washer pump will develop so a full port high pressure ball valve is required. This one came with the necessary male and female fittings so fitting it up was a simple matter of applying Teflon sealing tape and tightening the fittings up and installing the valve on the high pressure port. The seller even includes a roll of Teflon pipe tape for that purpose. ... show more
