Dylect® Pressure Washer Genuine Spare Part – Inlet Check Valve Assembly (Located in Pump Head – One-Way Water Intake Section) | POM Engineering Plastic | Compatible Only with Flow Prime Model (Pack of 3)
The Dylect® Inlet Check Valve Assembly is a genuine component engineered for the Flow Prime Pressure Washer. Positioned inside the pump head’s inlet chamber, it ensures one-way water entry by preventing reverse flow during plunger compression. Made from durable POM engineering plastic, it delivers high wear resistance, precision movement, and long service life in demanding pressure cycles.
A worn inlet check valve can cause weak suction, pulsation, or pressure drops. Service Note: Replace all three valves together to maintain balanced flow and consistent performance. Genuine Dylect parts ensure smooth water intake and long-term operational efficiency.
