How to Forcefully Silence Your Sprinkler System: A Simple 5-Step Guide to Keep It Quiet

As the cold season approaches, it’s crucial to prepare and protect your sprinkler system from the freezing temperatures. Shutting down your sprinkler system properly is essential to prevent damage and ensure its longevity. This blog post will provide a comprehensive guide on how to shut down sprinkler system, covering every step from preparing to closing the system.

Gather Necessary Tools

Before you begin, gather the following tools:

• Screwdriver or wrench
• Pliers
• Water key or hose bib key
• Bucket or hose
• Rags or towels

Prepare the System

• Turn off the Water Supply: Locate the main water valve controlling the sprinkler system and turn it off.
• Open Faucets and Sprinklers: Open all faucets and sprinklers in the system to release any remaining water pressure.
• Disconnect Hoses: Disconnect any hoses attached to the system.

Drain the System

• Locate Drain Valves: Find the drain valves located at the lowest points of the system, usually near the backflow preventer or manifolds.
• Open Drain Valves: Use a screwdriver or wrench to open the drain valves and allow water to drain out.
• Flush the Lines: Turn on the main water valve for a few seconds to flush any remaining water from the lines.

Protect the Backflow Preventer

• Locate the Backflow Preventer: Find the backflow preventer, which is typically located near the main water valve.
• Remove the Cap: Use a screwdriver or wrench to remove the cap on the backflow preventer.
• Drain the Backflow Preventer: Open the drain valve on the backflow preventer to drain any remaining water.

Protect the Sprinkler Heads

• Blow Out Sprinkler Lines: Use an air compressor to blow out any remaining water from the sprinkler lines.
• Cover Sprinkler Heads: Place sprinkler head covers over each sprinkler head to protect them from freezing.

Close the System

• Close Drain Valves: Tighten the drain valves to close them securely.
• Close the Main Water Valve: Turn the main water valve back on to ensure it’s fully closed.
• Protect the System from Freezing: If you live in an area with freezing temperatures, wrap the backflow preventer and sprinkler heads with insulation or frost cloth to prevent freezing.

Safety Precautions

• Wear gloves and safety glasses to protect yourself from water and debris.
• Use caution when handling compressed air equipment.
• Do not attempt to shut down the system if it’s frozen.
• If you encounter any difficulties, contact a licensed irrigator for assistance.

Questions We Hear a Lot

1. Why is it important to shut down my sprinkler system in the winter?

Freezing temperatures can cause water to expand and damage sprinkler lines, backflow preventers, and sprinkler heads. Shutting down the system prevents these damages.

2. How often should I shut down my sprinkler system?

It’s recommended to shut down your sprinkler system once the temperatures consistently drop below freezing.

3. Can I shut down my sprinkler system myself?

Yes, you can shut down your sprinkler system yourself if you have the necessary tools and follow the steps outlined in this guide. However, if you’re not comfortable doing it yourself, contact a licensed irrigator.

4. What happens if I don’t shut down my sprinkler system properly?

Improper shutdown can lead to frozen and burst pipes, damaged backflow preventer, and cracked sprinkler heads.

5. How can I prevent my sprinkler system from freezing during winter?

Wrap the backflow preventer and sprinkler heads with insulation or frost cloth, and ensure all water is drained from the system.

6. Can I use antifreeze to protect my sprinkler system from freezing?

Antifreeze is not recommended for sprinkler systems as it can damage the components. Use compressed air to blow out water instead.

7. What should I do if my sprinkler system freezes?

If your sprinkler system freezes, do not attempt to thaw it yourself. Contact a licensed irrigator for assistance to prevent further damage.
