How to Blow Out Pool Return Lines: Essential Steps for Winterizing Your Pool Safely

Ever wondered how to keep your pool in top shape during the colder months? If you live in an area where temperatures drop, blowing out your pool return lines is crucial. Neglecting this step can lead to costly damage and repairs come spring.

Picture this: it’s a chilly winter day, and you’re worrying about your pool. You know freezing water can wreak havoc on your plumbing. The good news is that with the right techniques, you can protect your investment and ensure your pool is ready for fun when the weather warms up. This article will guide you through the simple steps to blow out those return lines effectively, saving you time and money down the line.

Key Takeaways

• Protect Your Plumbing: Blowing out pool return lines is essential to prevent freezing and damage during colder months, ensuring your pool remains in top shape.
• Necessary Tools: Equip yourself with an air compressor, safety gear (glasses, gloves, ear protection), and proper fittings for effective and safe maintenance.
• Follow a Step-by-Step Process: Start by turning off the pump, lowering water levels, connecting the air compressor, and activating it to blow out the lines completely.
• Avoid Common Mistakes: Be cautious of using excessive pressure, neglecting safety equipment, or overlooking debris, as these can lead to inefficiencies and potential damage.
• Post-Job Inspection: After blowing out the lines, inspect return jets and fittings for moisture, and perform a system test to confirm that everything functions correctly.
• Consider Antifreeze: In climates prone to freezing, using antifreeze is advisable to further protect your pool plumbing system.

Importance Of Blowing Out Pool Return Lines

Blowing out pool return lines protects your pool’s plumbing from freezing during colder months. Ice expands, which can cause cracks or bursts in the lines. These issues lead to costly repairs and a damaged pool system come spring.

Properly winterizing the return lines involves removing water, preventing freezing damage. This simple maintenance step ensures your pool is ready for use as soon as warm weather returns. Additionally, blowing out the return lines helps maintain water quality by reducing bacteria growth from stagnant water.

You can avoid stress and save money by taking this precautionary measure. Regular maintenance, including winterizing return lines, keeps your pool investment in optimal condition and extends its lifespan.

Tools Needed For Blowing Out Pool Return Lines

You’ll need the right tools to effectively blow out pool return lines. This process prevents water from freezing in the lines during winter, protecting your pool’s plumbing. Here’s a list of essential tools:

Air Compressor

An air compressor is crucial for blowing out pool return lines. Look for a model with at least 30 PSI (pounds per square inch) of pressure. This ensures enough force to push out water from the lines. To use it, follow these steps:

1. Connect the air compressor to the return line using proper fittings.
2. Set the compressor to a low pressure to start.
3. Gradually increase the pressure until all water exits the line.

Safety Gear

Safety gear protects you while working on the pool. Equip yourself with the following items:

• Safety Glasses: Protect your eyes from debris or splashes.
• Gloves: Wear gloves to safeguard your hands from vibrations and sharp edges.
• Ear Protection: Use earplugs or earmuffs while operating the air compressor, as they can be quite loud.

Ensuring you have these tools and safety measures in place makes the process smooth and efficient.

Step-By-Step Guide To Blow Out Pool Return Lines

Blowing out pool return lines ensures your plumbing system is protected from freezing damage during colder months. Follow these steps for an efficient process.

Preparing The Pool

1. Turn Off the Pump: Always start by shutting off the pool pump to avoid any damage.
2. Remove Accessories: Take off any pool accessories such as skimmers or pool toys. This allows easy access to the return lines.
3. Lower the Water Level: Reduce the water level to below the return lines. Use a submersible pump if needed. This helps prevent water from being forced back into the lines.
4. Locate the Return Lines: Identify all return lines around the pool. This may vary based on your pool’s configuration.

Blowing Out The Lines

1. Connect the Air Compressor: Attach the air compressor to the designated return line using a blowout fitting or a hose adapter. Ensure a secure connection to prevent air leaks.
2. Set the Pressure: Adjust the compressor to at least 30 PSI. Do not exceed 50 PSI, as higher pressure can damage the plumbing.
3. Activate the Compressor: Turn on the air compressor. Watch for bubbling from the return jets, indicating air is moving through the lines. This may take several minutes.
4. Complete Each Line: Repeat the process for all return lines. Ensure each line is blown out completely before moving to the next line.

1. Inspect the Jets: Turn on the pool’s return jets after blowing out the lines. If water flows easily and there are no blockages, the process is successful.
2. Look for Ice Expansion: Check for any signs of ice or moisture around the return lines. Clear lines should show minimal to no moisture.
3. Monitor Freeze Warnings: If temperatures dip below freezing, take additional precautions like adding antifreeze to the lines. This step further prevents damage.

By following these steps, you can ensure your pool return lines are properly winterized, protecting your investment for the upcoming season.

Common Mistakes To Avoid

Avoiding mistakes during the process of blowing out pool return lines ensures efficiency and effectiveness. Here are several common pitfalls to watch out for:

• Using Excessive Pressure: Relying on high PSI can damage the pool return lines and fittings. Keep the compressor’s pressure at 30 PSI to prevent issues.
• Neglecting Safety Gear: Skipping safety goggles and ear protection during blowout can lead to injuries from debris or loud noises. Always wear protective gear.
• Failing to Clear Debris: Ignoring the removal of leaves and debris from the pool area before blowing out lines can cause blockages. Clean the area thoroughly for better results.
• Overlooking Jets and Return Fittings: Not inspecting jets and return fittings after blowout can allow water to remain trapped, which leads to freezing. Check all fittings for remaining moisture.
• Underestimating Antifreeze Needs: Believing that antifreeze isn’t necessary in milder climates can result in freezing. Use antifreeze where appropriate to add additional protection.
• Not Testing the System: Skipping post-blowout testing can allow freezing to go unnoticed. After completing the blowout, run the system briefly to ensure everything operates correctly.

Being mindful of these common mistakes will streamline the winterization of your pool return lines and help safeguard your investment.

Conclusion

Taking the time to properly blow out your pool return lines can save you from headaches and expenses down the road. By following the steps outlined and avoiding common pitfalls you’ll keep your pool in great shape through the winter months. Remember to stay safe and check every part of your system to ensure everything’s working as it should. With a little effort now you’re setting yourself up for a smooth and enjoyable swimming season when the warmer weather returns. Happy winterizing!
