Importance Of Blowing Out Swimming Pool Lines

Blowing out swimming pool lines prevents expensive damage during winter. Water left in the lines can freeze, expand, and crack pipes, fittings, and equipment. This damage can lead to significant repair costs when spring arrives.

Blowing out pool lines also protects the pool’s overall system. A properly winterized pool maintains its structure and functionality. This step ensures that the plumbing and filtration systems remain intact, allowing for smoother reopening in the spring.

Several tools make blowing out pool lines easier. You’ll typically need a shop vac or air compressor, along with appropriate fittings for the pool’s plumbing. These tools help you effectively remove water from the lines and prevent freeze-related issues.

When blowing out pool lines, follow these practical tips:

1. Turn Off the Power: Always start by turning off the power to the pool equipment.
2. Remove Jets and Fittings: Take off any fittings, such as skimmer plugs and return jets, to access the plumbing more easily.
3. Start at the Deep End: Begin blowing out lines at the deepest end of the pool, working toward the shallow end.
4. Clear All Lines: Ensure all lines, including main drain and skimmer lines, are completely free of water.
5. Leave Lines Open: Leave the lines open and allow any remaining water to drain to avoid freezing and damage.

By following these steps, you maintain your pool in optimal condition and save yourself from costly repairs. Proper winterization allows you to enjoy a worry-free spring opening.

Required Tools And Equipment

Blowing out swimming pool lines for winter requires specific tools and equipment. Having the right items ready makes the process more efficient and effective.

Air Compressor

An air compressor is essential for blowing out pool lines. Choose a compressor with a minimum capacity of 2 CFM at 90 PSI to ensure adequate pressure. Connect the compressor to the pool’s plumbing using a blowout plug or adapter. This connection allows for direct airflow into the lines, pushing out water and moisture effectively.

Additional Supplies

Gather these additional supplies for a complete setup:

• Blowout Plug: Use this to seal the skimmer or return lines for focused pressure.
• Hoses: Ensure you have hoses long enough to connect the air compressor to the pool lines.
• Wrenches: Use adjustable wrenches to remove fittings and connectors as needed.
• Safety Goggles: Protect your eyes from debris that may dislodge during the process.
• Towels: Keep towels handy to wipe up any excess water before and after the process.

These tools streamline the winterization of your pool, preventing damage from freezing temperatures.

Step-By-Step Guide To Blow Out Pool Lines

Follow these steps to effectively blow out your pool lines for winter. Ensure your equipment is ready and take precautions to prevent freezing.

Preparing The Pool

• Check the pool’s water level. Ensure it’s low enough to prevent water from remaining in the lines.
• Turn off the pool pump and any associated equipment. This action prevents accidental activation during the process.
• Remove all fittings and accessories. Disconnect any hoses from skimmers, main drains, and returns. Store these items safely for winter.

Blowing Out Main Drain Lines

• Attach the blowout plug to the main drain. This plug prevents air from escaping.
• Connect your air compressor to the blowout plug. Ensure a tight seal to maximize air pressure.
• Start the compressor and let it run until you see bubbles. This indicates that the water is being displaced.
• Monitor for any remaining water. If you still see water, continue the process until it’s completely cleared.

Blowing Out Return Lines

• Move to the return lines after finishing the main drain.
• Insert the blowout plug into the first return line. Secure it firmly.
• Connect the air compressor.
• Blow air through the return line. Watch for bubbles at the water’s surface, signifying that the line is clear.
• Repeat this process for each return line, ensuring all are completely free of water.

• Once all lines are cleared, detach the compressor and plug from the lines.
• Leave the main drain and return lines open. This action allows any residual moisture to escape.
• Inspect all equipment and lines for any leftover water. Wipe down surfaces to prevent freeze damage.
• Store any removed fittings and accessories in a dry location, ready for spring reopening.

Following these steps helps ensure your pool remains in excellent condition throughout winter.

Common Mistakes To Avoid

Avoiding common mistakes during the winterization of your pool lines ensures a smoother process. Here’s a list of pitfalls to watch out for:

• Not Using the Right Equipment: Use an air compressor designed for the task. A less powerful compressor may not expel all the water.
• Skipping Line Check: Check all lines before starting. Neglecting to inspect can lead to blockages, making it hard to clear all water.
• Overlooking the Main Drain: Focus on the main drain. Failing to blow it out can lead to damage if water freezes.
• Using Water Instead of Air: Do not introduce water into the lines after blowing them out. This can leave pockets of water that freeze and expand.
• Rushing the Process: Take your time during each step. Hurrying might result in missed areas or incomplete blowing of the lines.
• Ignoring Local Temperatures: Pay attention to weather conditions. If cold temperatures are forecasted before your winterization, complete the process sooner.
• Neglecting Return Lines: Run air through all return lines thoroughly. Failing to do this elevates the risk of freeze damage in those areas.
• Leaving Fittings Attached: Remove all fittings and plugs. Leaving them in can trap water and create problems later.

By steering clear of these mistakes, you’ll protect your pool system effectively this winter.

Conclusion

Taking the time to properly blow out your swimming pool lines can save you from costly repairs come spring. By following the steps outlined and avoiding common pitfalls you’ll ensure your pool is well-prepared for winter.

Remember to check all lines and use the right equipment to make the process smooth. With a little patience and attention to detail you’ll protect your pool system effectively. Enjoy the peace of mind that comes with knowing you’ve winterized your pool the right way.
