Sprinkler System Winterization: How to Avoid Costly Repairs by Emptying Properly

A well-maintained sprinkler system is crucial for keeping your lawn and garden healthy and thriving. However, when winter approaches, or if you need to perform maintenance or repairs, it’s essential to know how to empty the sprinkler system properly. This comprehensive guide will provide you with detailed instructions on how to empty your sprinkler system, ensuring a smooth and efficient process.

Safety Precautions

Before you begin emptying your sprinkler system, it’s vital to take safety precautions:

• Wear gloves: Protect your hands from sharp edges or debris.
• Turn off the water supply: Locate the main water valve and turn it off to prevent water from flowing into the system.
• Open faucets: Open all faucets and valves connected to the sprinkler system to release any remaining water.

Step-by-Step Instructions: How to Empty Sprinkler System

1. Locate the Blowout Valve

Identify the blowout valve, which is typically a small, red valve located at the lowest point of the sprinkler system.

2. Attach an Air Compressor

Connect an air compressor to the blowout valve using a quick-connect fitting. Ensure the compressor is rated for at least 50 PSI.

3. Open the Blowout Valve

Slowly open the blowout valve to allow compressed air to enter the system. Gradually increase the pressure to 50 PSI.

4. Open Sprinkler Heads

Walk around your yard and manually open each sprinkler head by turning the adjustment screw counterclockwise.

5. Blow Out Water

Continue blowing compressed air into the system until all the water has been forced out of the sprinkler heads. You may hear a hissing sound as the water escapes.

6. Close Sprinkler Heads

Once all the water has been blown out, close the sprinkler heads by turning the adjustment screws clockwise.

7. Close Blowout Valve

Once all the sprinkler heads are closed, close the blowout valve.

8. Detach Air Compressor

Disconnect the air compressor from the blowout valve.

Troubleshooting: How to Empty Sprinkler System

Problem: Water remains in the system after blowing out.

• Solution: Ensure all sprinkler heads are fully open and the blowout valve is fully closed. If necessary, use a wrench to tighten the blowout valve.

Problem: Air compressor is not powerful enough.

• Solution: Use an air compressor with a higher PSI rating.

Problem: Sprinkler heads are frozen.

• Solution: If the sprinkler heads are frozen, thaw them using a heat gun or a bucket of warm water.

Maintenance Tips

After emptying your sprinkler system, perform the following maintenance steps:

• Lubricate valves: Apply a few drops of silicone lubricant to all sprinkler valves to prevent them from sticking.
• Inspect sprinkler heads: Check for any damage or leaks and replace any faulty heads.
• Cover system: Protect the sprinkler system from freezing temperatures by covering it with insulation or a tarp.

Wrapping Up: How to Empty Sprinkler System

Following these step-by-step instructions, you can efficiently empty your sprinkler system, ensuring its proper maintenance and longevity. Remember to take safety precautions and perform regular maintenance to keep your sprinkler system functioning optimally.
