Dylect® Pressure Washer Genuine Spare Part – Outlet Check Valve Assembly (Located in Pump Head – One-Way Discharge Section) | POM Engineering Plastic | Compatible Only with Flow Prime Model (Pack of 3)
The Dylect® Outlet Check Valve Assembly is a genuine spare part designed to regulate one-way water discharge inside the Flow Prime Pressure Washer pump head. Made from durable POM engineering plastic, it delivers stable performance, wear resistance, and precise motion under repeated high-pressure cycles.
A damaged outlet check valve can cause pressure instability or backflow into the pump. Service Note: Replace all three valves at once to maintain proper pressure balance and consistent output. Genuine Dylect parts ensure reliable flow control and stable long-term operation.
