Function of the Check Valve Kit

The check valve kit helps:

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

Replacing worn check valves helps restore pressure washer performance while maintaining reliable pump operation.

Common Signs Replacement Is Needed

Replace the check valve kit if you notice:

• Reduced operating pressure
• Pulsating or inconsistent pressure
• Decreased water flow
• Pump surging
• Internal valve wear
• Damaged valve caps
• Pump rebuild or scheduled preventive maintenance

Replacing worn valves and valve caps early helps prevent additional wear to the manifold and other internal pump 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 caps and check valve assemblies.
• Clean all valve bores and sealing surfaces thoroughly.
• Inspect the manifold for wear or damage.
• Install the new valve assemblies and valve caps according to the manufacturer's specifications.
• Reassemble the pump and verify proper pressure and leak-free operation.

Important: Inspect packings, water seals, O-rings, ceramic plungers, and valve seats during service. Replacing related wear components together 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.
• Inspect valve caps for damage or thread wear during service.
• Use clean, filtered inlet water to reduce valve wear.
• Use only genuine OEM AR replacement parts to maintain optimum pump performance, reliability, and long service life.
