Draining your sprinkler system before winter is crucial to prevent damage from freezing temperatures. Here's how to do it:
1. Turn Off the Water Supply
- Locate the main water valve for your sprinkler system. It's usually near the water meter or in a utility room.
- Turn the valve clockwise to shut off the water supply.
2. Open the Sprinkler System's Drain Valves
- Most sprinkler systems have drain valves located at low points in the system. These valves are usually marked with a "drain" or "winterization" label.
- Open these valves to allow water to drain out of the pipes.
3. Run the Sprinklers
- Once the drain valves are open, run the sprinkler system for a few minutes. This helps to force any remaining water out of the pipes.
4. Check for Water
- After running the system, check for any leaks or signs of water in the pipes. If you see any water, repeat steps 2 and 3 until the system is completely drained.
5. Close the Drain Valves
- Once the system is drained, close the drain valves.
6. Winterize Your Backflow Preventer
- Backflow preventers are essential components of your sprinkler system that prevent contaminated water from flowing back into your drinking water supply. They need to be winterized as well.
- You can either hire a professional to winterize your backflow preventer or do it yourself following the manufacturer's instructions.
7. Cover Your Sprinkler Heads
- Cover your sprinkler heads with protective caps or bags to prevent debris from entering and freezing.
8. Disconnect and Store Your Sprinkler Timer
- If your sprinkler timer is an older model, you may need to disconnect it and store it indoors for the winter. Newer timers are typically weatherproof and can be left outside.
By following these steps, you can effectively drain your sprinkler system and protect it from winter damage.
