Introduction: Protecting Your Pool Plumbing System

Blowing out your pool lines is a crucial step in winterizing your pool. This process removes all water from the plumbing system, preventing pipes from freezing and cracking. Ignoring this step can lead to costly repairs in the spring. This guide provides a step-by-step approach to ensure you do it correctly. Let's dive in and learn how to properly blow out those pool lines!

What You'll Need: Gathering Your Supplies

Before you begin, gather these essential tools and supplies:

Air compressor: A portable air compressor with at least 100 PSI is ideal.
Air blower adapter: This connects your compressor to the pool's plumbing system. Make sure it's compatible with your pool's equipment.
Pool plugs: Ensure all returns, skimmers, and main drains are securely plugged.
Shop Towels: These will come in handy for cleaning up any spills.
Water key: If you have one, this facilitates easier access to the pool's plumbing.
Safety Glasses: Protection is key when working with compressed air.
Gloves: Protect your hands from potential cuts and abrasions.
Pressure Gauge: Monitor the air pressure during the blowing-out process.

Step-by-Step Guide: Blowing Out Your Pool Lines

1. Turn off Equipment: Before you start, turn off all pool equipment including the pump, filter, and heater.

2. Securely Plug All Openings: Make sure all openings to the plumbing system (returns, skimmers, and main drains) are securely plugged to prevent air leakage.

3. Attach the Air Compressor: Connect the air blower adapter to the return line. This is usually the largest diameter pipe leading from the pump.

4. Turn on the Air Compressor: Slowly increase the air pressure to the recommended PSI (usually around 20-30 PSI, but check your compressor's manual). Never exceed the maximum pressure rating of your pool equipment.

5. Check for Leaks: While the air compressor is running, carefully observe all connections and fittings for any air leaks. If you see bubbles in the pool, you have a leak, and you'll need to re-secure the connection or plug.

6. Monitor the Pressure: Observe the pressure gauge on your air compressor. A consistent pressure reading indicates that the lines are clear of water. If the pressure drops significantly, you may have a blockage or leak.

7. Reverse the Process: Once the lines are clear, slowly reduce the air pressure to zero and turn off the air compressor.

8. Remove the Adapter: Carefully disconnect the air blower adapter from the return line.

9. Final Check: Before winterizing the rest of your pool, conduct a final check around all connections to ensure there are no leaks.

Troubleshooting Common Issues

Air Leaks: If you notice air leaks, carefully check all plugs and connections. Tighten any loose connections or replace damaged plugs.
Low Air Pressure: Ensure your air compressor is properly functioning and that you have enough power for the job. A clogged air filter on your compressor can also limit air output.
Blockages: If you cannot blow out the lines completely, there might be a blockage within the plumbing system. This will require professional help.
