Step-by-Step Guide On How To Blow Out Inground Pool Lines

Blow out your inground pool lines before winter arrives to prevent expensive damage from freezing. Although complex, this process can be simplified using the correct equipment and technique. This comprehensive winterizing guide will help you guarantee that your pool lines are winter-ready, preserving your investment for next season.

Step 1: Connecting the Air Compressor

Firstly, you’ll need an air compressor for pool maintenance. Not just any air compressor, but one that fits the volume and pressure required for pool lines. Connect your air compressor to the pool pump system with the suitable adapter. Make sure every connection is solid and tight to stop any air leakage. This is the basis of the process; thus, be sure your setup is perfect twice-checked!

Step 2: Blowing Out the Skimmer Line

Then, the skimmer line comes next. Start with your air compressor set to a suitable and moderate pressure; it’s about finding that sweet spot where the air moves but not too forcefully and aggressively. Starting with the air hose in the skimmer line, slowly raise the airflow. A clue that the line is emptying is bubbles developing from the skimmer in the pool. Remember, patience is essential; let the air steadily force any water through the line.

Step 3: Blowing Out the Main Drain

The depth and accessibility of the main drain make blowing it a bit challenging. From what you used for the skimmer line, slightly raise the air pressure. Till you notice a steady stream of bubbles coming from the pool drain, direct the airflow into the main drain line. This suggests an almost clear line efficiently driven out of the water. Stay under-pressurized since it can ruin your pipes!

Step 4: Blowing Out Return Lines

You will have to lower the air compressor setting for the return lines. Attach the air hose to every return line separately and blow them out until bubbles or the distinct sound of air replacing water in the lines shows results. Depending on the reaction from the lines, you should change the air pressure; too much pressure can damage things, so keep it light and gentle.

Step 5: Final Checks

Now comes the last touches. Go over every line once more to guarantee no water remains. This could call for some brief air bursts across every line. Once you’re confident the lines are empty, plug them firmly. This stops freeze damage and any water from slinking back into the lines in the winter.

Aftercare and Maintenance

Plugging the Lines

After draining the water, use thread seal tape and plugs to secure all lines. Cover the pool with a winter cover for added protection.

Adding Pool Antifreeze (Optional)

Consider adding pool antifreeze to your skimmer and return lines to safeguard against freezing damage in freezing climates.

Covering the Pool

The Pool Circulation System Guide You Need Now

Understanding Pool Circulation System Every pool owner wants their swimming water to stay clean and free from algae, scaling, and other problems. The secret lies in a well-functioning circulation system, which is the engine that keeps everything working together. Think of it like the circulatory system in the body—without proper functioning, the total balance is lost. The pump, the heart of this system, draws water through skimmers, drains, and outlets, ensuring debris is removed before it reaches the filter. Once filtered, treated, and heated, the water is returned through the returns, keeping the pool walls free of buildup. In simple words, “A pool circulation system filters and sanitizes water using a pump, filter, skimmer, and returns to maintain water clarity and hygiene.“ A major issue arises when any components fail. Failure to fix issues in time can lead to medical bills for swimmers, rising energy bills, and an increase in treatment costs. The right way to optimize this system is through regular DIY maintenance and knowing how this system works. A little effort in eradicating early signs of breaks prevents big regrets later.

How Professionals Lower Alkalinity in Pool Fast

Maintaining the right total alkalinity in pool water is important because it helps the water resist sudden changes in pH and keeps chlorine working effectively. Alkalinity is the ability of water to neutralise acids, and it comes from alkaline salts like calcium and magnesium. The recommended range for swimming pools is between 100–150 ppm (parts per million), but if it gets higher, the pH can drift upward, making the water cloudy and unstable. This affects the stability of disinfectants, preventing them from doing their job in sanitizing the pool. High alkalinity can also impact pool finishes, leading to deposits that make surfaces rough over time. To fix high alkalinity, you can use muriatic acid or sodium bisulfate, also known as a pH reducer. Begin by measuring the TA levels with a sample test kit to see if they fall within the ideal range. If needed, add the desired amount of acidic substance carefully, as it will react with the water to lower the alkalinity. After adding, aerate the water to help the pH stabilize within 7.2–7.8, preventing it from becoming less stable. Regular measurements are key to controlling alkalinity and ensuring that pools, hot tubs, and aquariums stay clean and
