Step 1: Turn off the Water Supply
The first step in how to drain sprinkler system is to turn off the water supply. Locate the main valve that controls the water supply to your irrigation system and turn it off. This valve is typically located near your water meter or in a valve box in your yard.
Step 2: Open all Valves and Drain the Water
Next, open all the valves on your sprinkler system to allow the water to drain out. This includes the backflow preventer, which is usually located near the main valve. You can also manually open each sprinkler valve to let the water drain out. Be sure to let the water drain completely.
Step 3: Use a Compressor to Remove Any Remaining Water
After you have drained as much water as possible from your system, you can use a compressor to blow out any remaining water. Connect the compressor to your sprinkler system using an air hose and blow out each sprinkler zone until no more water comes out.
Step 4: Remove and Store Sprinkler Heads
It’s a good idea to remove and store your sprinkler heads for the winter to protect them from damage. Use a wrench to unscrew each sprinkler head from its fitting and store them in a dry place.
Step 5: Inspect Your System for Damage
While you are draining your sprinkler system, take the opportunity to inspect it for any damage or wear and tear. Look for cracked pipes, broken sprinkler heads, or other issues that may need to be addressed before you use your system again in the spring.
