Step-by-Step Instructions: How to Blow Out Irrigation System

Step 1: Turn Off the Water Supply

Before starting, shut off the water supply to your irrigation system. Locate the main water valve and turn it off to ensure no additional water flows into the pipes.

Step 2: Remove Valve Covers

Open the covers of your irrigation control valves. This allows for easier air circulation through the system when you attach the air hose in later steps. Each valve should be accessible for air to efficiently clear out trapped water.

Step 3: Set Up the Air Compressor

Connect your air compressor to the irrigation blowout port or hose adapter, typically found near the water source. Ensure all connections are secure to optimize airflow. Adjust the air pressure to the recommended level as per your systems manual, typically between 50 to 80 PSI.

Step 4: Activate Your Zones

Manually activate each irrigation zone, one at a time, using your systems controller. Turn on one zone and use the air compressor to push water out until only mist or air flows from the sprinkler heads.

Important: Do not exceed the advised air pressure to avoid damaging the pipes.

Step 5: Repeat for All Zones

Continue blowing out each zone systematically. Always allow time for the compressor to recharge if needed. Operating a compressor thats repeatedly overloaded can shorten its lifespan.

Step 6: Check and Double-Check

After blowing out all zones, inspect each sprinkler head and valve for residual water. Small amounts of water may remain in low areas of the systemif so, repeat the process as necessary.

Tips for Safe and Effective Blowouts

• Always wear protective goggles to safeguard your eyes, especially if debris or water escapes suddenly.
• Use a compressor designed for irrigation use. High-powered industrial compressors can inadvertently damage your system.
• Dont rush. Allow each zone adequate time to clear out all water.
