Floraflex Lateral Flush Valve – Air Relief & System Flush

Lateral Flush Valve – Keeps Your Irrigation Running Smooth

The Lateral Flush Valve is a simple but vital component that helps prevent clogging and air build-up in your irrigation system. Installed at the end of each watering zone, this valve flushes debris before every irrigation event and releases trapped air as the system fills with water — protecting your emitters and maintaining consistent performance.

Key Features

• 2-in-1 design: Combination air relief and flush valve.
• Prevents clogging: Automatically flushes debris before each cycle.
• Air relief function: Expels trapped air to stabilise water flow.
• Durable build: Made from weather-resistant, non-corrosive materials.
• Easy maintenance: Removable top for quick access and cleaning.
• Variable flow diaphragm: Flip for low or high flow applications.

Flow & Pressure Ratings

• Low Flow Side: 2–5 GPM
• High Flow Side: 5–12 GPM
• Operating Pressure: 8–25 PSI

Maintenance & Diaphragm Cleaning

To remove or adjust the diaphragm, rotate the green locking ring counter-clockwise to lift the cover. You can then remove the diaphragm for cleaning or flip it over to switch between low-flow and high-flow configurations.

Tip: Always install the Lateral Flush Valve at the end of your watering zone for the best performance and system protection.
