Step 1: Turn off the Water Supply

Shut off the water supply to your sprinkler system. Locate the main shut-off valve, usually located nest to the green manifold box and turn it off to stop the flow of water to the system. ( Off is Righty Righty) This step prevents water from entering the system during the winter months.

Step 2: Release Pressure

To prevent any remaining water from freezing and causing damage, release the pressure in your sprinkler system. Open all the control valves and manually activate each zone to release any trapped water. This step helps to avoid potential freezing and cracking of pipes.

Step 3: Drain the System

Properly draining your sprinkler system is crucial for winterization. Start by opening all the drain valves and allow the water to flow out. If your system has manual drain valves, open them to remove any water from the pipes. Additionally, you can use compressed air to blow out the remaining water from the system. It’s recommended to consult a professional for the correct air pressure and technique.

Step 4: Insulate Exposed Components

Protect any exposed components of your sprinkler system by insulating them. Use foam pipe insulation or insulating tape to cover exposed pipes, valves, and backflow preventers. This insulation helps to prevent freezing and potential damage caused by low temperatures.

Step 5: Regular Maintenance

Perform regular maintenance on your sprinkler system to ensure its optimal functioning. This includes inspecting and repairing any leaks, adjusting sprinkler heads, and checking the overall system for any issues. Regular maintenance extends the lifespan of your system and prepares it for the winter season.
