Inlet check valves and discharge check valves found within a Karcher pump manifold assist the pump in creating high pressure. They can sometimes become damaged by foreign debris that is flushed through the water source, such as small pebbles or sand. We highly recommend replacement of Karcher pump valves whenever replacing any Karcher pump seals.
This Pressure Washer Pump Valve Kit contains 6 valves (3 inlet check valves and 3 discharge valves), which is the total necessary for rebuilding most pressure washer pumps.
