Function of the Valve Kit

The valve kit helps:

  • Control one-way water flow through the pump
  • Maintain proper operating pressure
  • Prevent water backflow
  • Improve pump efficiency
  • Restore consistent pressure and water flow
  • Protect internal pump components from premature wear

Replacing worn valve assemblies helps restore pressure washer performance while maintaining smooth, reliable pump operation.


Common Signs Replacement Is Needed

Replace the valve kit if you notice:

  • Reduced operating pressure
  • Pulsating or inconsistent pressure
  • Decreased water flow
  • Pump surging
  • Worn or damaged valve assemblies
  • Damaged O-rings
  • Pump rebuild or scheduled preventive maintenance

Replacing worn valves promptly helps prevent additional wear to the pump manifold and other internal components.


Installation & Service Notes

  • Shut down the pressure washer and relieve all system pressure.
  • Remove the pump manifold according to the manufacturer's service procedures.
  • Carefully remove the existing valve assemblies and O-rings.
  • Clean all valve bores and sealing surfaces thoroughly.
  • Inspect the manifold for wear, corrosion, or debris.
  • Install the new OEM valve assemblies and O-rings in the correct orientation.
  • Reassemble the pump and verify proper pressure and leak-free operation.

Important: Inspect packings, water seals, ceramic plungers, and valve seats during service. Replacing related wear components at the same time helps maximize pump reliability and service life.


Maintenance Recommendations

  • Inspect check valves during routine pump maintenance.
  • Replace worn valve assemblies at the first signs of pressure loss or pump surging.
  • Use clean, filtered inlet water to minimize valve wear.
  • Flush the pump after use when handling dirty or corrosive water.
  • Use only genuine OEM Comet replacement parts to maintain optimum pump performance, reliability, and long service life.
