Let’s dive in.
Preparing The Sprinkler System
Start by turning off the main water supply to the sprinkler system. This stops water from flowing while working. Next, open all manual drain valves to let water escape from pipes. This helps avoid frozen pipes during cold weather.
Locate the sprinkler system’s backflow preventer and open its test cocks. This releases any trapped water inside the system. Remove or turn off any automatic timers or controllers to prevent accidental starts.
- Turn off the water supply.
- Open manual drain valves.
- Open backflow preventer test cocks.
- Disable automatic timers.
Check each sprinkler zone to ensure all valves are open. This allows air to flow through the pipes. Finally, prepare the air compressor or blower used for blowing out the system. Make sure it is ready before connecting to the sprinkler system.

Gathering Necessary Tools
Gathering the right toolsis key for blowing out a Rainbird sprinkler system. You will need a compressed air source, like an air compressor. Make sure it has a pressure gauge and a hose long enough to reach the sprinkler system.
Also, grab a quick-connect fittingthat matches your sprinkler system’s backflow preventer. This helps connect the air compressor safely. Don’t forget to have a pressure regulatorto control the air pressure and avoid damaging pipes.
- Air compressor with at least 50 PSI
- Quick-connect fitting for Rainbird systems
- Pressure regulator
- Safety goggles and gloves
- Wrench or pliers for fittings
Wear safety gear. Always protect your eyes and hands during this task. Proper tools and safety make the job easier and safer.
Shutting Off The Water Supply
Locate the main water valve for your Rainbird sprinkler system. It is usually near the water meter or where the sprinkler pipes start. Turn the valve clockwise to close it and stop the water flow. This step is essentialto protect your system from damage during blowout.
After shutting off the valve, open a faucet outside to release pressure in the pipes. This helps drain remaining water. Also, open the manual drain valves if your system has them.
- Close the main water valve fully.
- Open an outside faucet to relieve pressure.
- Open manual drain valves if available.

Using An Air Compressor For Blowout
Turn off the main water supply. Locate the backflow preventer valve. Open the valve slowly to release pressure. Connect the air compressor to the blowout port. Use a hose adapter for a tight fit. Set the air pressure to 50 PSI.
Start the air compressor. Watch the sprinkler heads closely. They should pop up and release water. Move from one zone to another. Repeat until all zones are clear. Do not exceed 2 minutes per zone.
Turn off the air compressor. Disconnect the hose carefully. Close all valves tightly. Check for any remaining water. Ensure the system is dry before winter.
Safety Tips And Final Checks
Turn off the main water supplybefore starting the blowout process. Use a proper air compressorrated for sprinkler systems to avoid damage. Always wear safety gogglesto protect your eyes from debris and water spray.
Check that all sprinkler heads are fully exposed and clear of obstacles. Open all manual drain valves to let water escape. Release pressure slowly to prevent pipe bursts.
- Never use high pressure above recommended limits.
- Keep children and pets away during the process.
- Inspect the system after blowout for cracks or leaks.
- Store equipment safely after use.
