As the cold winter months approach, ensuring your sprinkler system is adequately prepared for the dropping temperatures is crucial. Sprinkler winterization removes all the water from the system to prevent freezing and damage to the pipes, valves, and sprinkler heads. Here are some steps to help you winterize your sprinkler system.

1. Turn off the water supply

The first step in winterizing your sprinkler system is to turn off the water supply. This can be done by finding the shut-off valve controlling the water flow to the system and turning it to the off position. This will prevent water from flowing into the system and help prevent damage from freezing.

2. Drain the water

Once the water supply is turned off, it’s time to drain the water from the system. This can be completed in several ways, depending on your system type. One standard method is to use compressed air to push the water out of the system. This is usually done by connecting an air compressor to the design and opening the valves to allow the air to push the water out. Another method is to manually drain the water from each zone of the system by opening the drain valves and allowing the water to flow out. This latter method will only work if the entire system is sloped correctly. This is rare.

3. Insulate exposed pipes

If you have any exposed pipes or valves, insulating them is essential to help prevent freezing. You can use pipe insulation or even old towels or rags to wrap around the pipes and valves. This will help them retain heat and prevent them from freezing and potentially bursting until you can hire a professional to push all the water out.

4. Check for leaks

Before shutting down your system for the winter, searching for any leaks or damage to the pipes, valves, and sprinkler heads is essential. Look for any indications of water damage or leaks and make necessary repairs before shutting down the system. This will help prevent any further damage during the winter months.

5. Hire a professional

If you’re not comfortable winterizing your sprinkler system or have a complex system requiring special attention, it’s a good idea to hire a professional to do the job. A professional sprinkler service can ensure your system is properly winterized and ready to go when spring arrives.
