One of these Jetter Valves is installed in the middle inlet valve in place of the cap and valve normally found on an AR pressure wash pump. Once installed, it creates pulsations in the flow - turning your pressure washer into a "jetter".
Combining this valve with a foot valve (to control the flow) and a jetter hose with a jetter nozzle will convert your current pressure washer into another income stream!
NOTE: To be used at 3000 PSI or less. Not exactly as shown, but similar.
