Products Description
2100 Cleaning Machine Check Valve
Product Overview
This check valve is a replacement component for the pump of a 2100 series pressure washer or cleaning machine. It controls the one-way flow of water within the pump, which is crucial for building and maintaining proper water pressure. A faulty check valve often leads to symptoms like pulsating water flow, pressure loss, or a shaky machine . This is a commonly worn part that can be replaced to restore the machine's cleaning performance.
Technical Profiles & Materials
One-Way Flow Control – Prevents water backflow into the pump, maintaining consistent pressure at the nozzle. Common failure point when pressure drops after 1 second of trigger pull .
Pump Protection – Maintains system pressure and prevents reverse flow damage. Failed check valves cause pressure loss and reduced cleaning effectiveness .
Axial Pump Compatibility – Designed for 2100 PSI axial pumps, including Annovi Reverberi pumps used in Lifan and similar pressure washer brands .

FAQ
Q: How to identify the correct check valve for my 2100 pressure washer?
A:Check your pump model number (not the engine). Lifan units use AR RPV pumps – contact Lifan Power USA or Annovi Reverberi with pump model for correct part number .
Q: What are symptoms of a bad check valve?
A: Pressure loss after 1 second of trigger pull, inconsistent spray, or reduced cleaning effectiveness. On Homelite HL80833, this is a common failure point .
Q: Can I replace the check valve myself?
A: Yes, check valves are accessible on most axial pumps. Locate the pump model number first to ensure correct part fitment. Remove pump head, replace check valve and spring, reassemble .
