How to Close Above Ground Pool with Sand Filter: Complete Guide for Winter Preparation

Are you wondering how to close your above ground pool for the season? It can feel overwhelming with all the steps involved, especially if you want to ensure your pool stays in great shape. Many pool owners face the same challenge each year, but it doesn’t have to be a hassle.

Key Takeaways

• Preparation is Key: Thoroughly clean the pool by skimming, vacuuming, and brushing before closing to prevent algae and debris buildup.
• Adjust Water Levels: Lower the water level to 4-6 inches below the skimmer to prevent freezing damage during the winter months.
• Winterize Your Sand Filter: Backwash and rinse the sand filter before adding winterizing chemicals to maintain water quality and filter efficiency.
• Securely Cover the Pool: Use a suitable pool cover, ensuring it is properly secured to keep out debris and insulate the pool during winter.
• Follow Spring Reopening Steps: Inspect the sand filter, clean the pool, and balance the water chemistry to prepare for a safe and enjoyable swimming season.

Preparing The Above Ground Pool For Closing

Preparing your above ground pool for closing involves a few essential steps that set the stage for a smooth process. Follow these actions to ensure your pool is ready for winter.

Cleaning The Pool

Cleaning your pool is vital before closing. Start by removing debris with a skimmer net. Vacuum the bottom to eliminate dirt and leaves. Use a pool brush to scrub the sides and corners, targeting any algae or buildup. Test and balance your water chemistry, ensuring pH levels are between 7.2 and 7.8, and chlorine levels are at least 3 ppm. After cleaning, run the pump for 24 hours to circulate chemicals properly.

Water Level Adjustment

Adjusting the water level is crucial for winterizing your pool. Drain it to about 4-6 inches below the skimmer. This level prevents freezing water from damaging the skimmer and plumbing lines. If you live in a cold climate, consider lowering the water level more to protect the pool’s walls. After adjusting the water level, place winterizing plugs in the skimmer and return lines to prevent ice damage throughout winter.

Winterizing The Sand Filter

Properly preparing your sand filter for winter can help avoid damage and ensure it operates efficiently when spring arrives. Follow these steps for winterizing your sand filter effectively.

Backwashing The Sand Filter

Backwashing is essential for cleaning the sand filter before winter. Here’s how to do it:

1. Turn Off the Pump: Always start by turning off your pump.
2. Set the Multiport Valve: Change the valve position to “Backwash.”
3. Turn On the Pump: Run the pump for about 2-3 minutes. This helps remove dirt and debris from the filter.
4. Rinse the Filter: Switch the valve to “Rinse” and run the pump for another 1-2 minutes. This helps clear any remaining particulate matter.
5. Return to Filter Mode: Set the valve back to “Filter” position once the rinsing is complete.

This cleaning process ensures a cleaner filter, reducing the risk of mold or damage during the off-season.

Adding Winterizing Chemicals

Adding winterizing chemicals to your sand filter maintains water quality and protects the system. To do this:

1. Shock Treatment: Add a chlorine shock treatment to eliminate bacteria and algae. Ensure the pool water is balanced before adding.
2. Winterizing Algaecide: Pour in a winterizing algaecide designed for long-term protection. Follow the manufacturer’s instructions for dosage.
3. Stabilizer: If necessary, add a stabilizer to help maintain the effectiveness of the chlorine while the pool is closed.
4. Run the Pump: After adding chemicals, run the pump for at least 24 hours to ensure proper circulation and distribution.

These steps help prevent algae growth and ensure a clean start when reopening your pool in the spring.

Closing The Pool

Closing your above ground pool involves several key steps to ensure protection and maintenance through the winter months. Focusing on draining and covering the pool effectively safeguards your investment.

Draining The Pool

Draining the pool correctly prevents damage from freezing water. Ensure your water level is lower than the skimmer and return fittings. Follow these steps to drain your pool:

1. Turn Off the Pump: Always start by turning off the pump to avoid damage during the draining process.
2. Use a Submersible Pump: Place a submersible pump in the shallow end. Connect the hose to direct water away from the pool area.
3. Monitor Water Level: Keep an eye on the water level while the pump runs. Stop once the water level is below the skimmer.
4. Remove Water from Lines: Use a blower or shop vacuum to clear water from your pool’s return lines and skimmer. This step prevents freezing damage.

Covering The Pool

A proper cover keeps debris out and insulates the pool for winter. Follow these steps for effective covering:

1. Choose the Right Cover: Select a cover designed for above ground pools. Options include mesh, solid, or winter covers.
2. Clean the Pool: Remove any debris from the surface to prevent buildup.
3. Secure the Cover: Use water bags or stakes to secure the cover on all sides. Ensure it fits snugly to prevent wind from lifting it.
4. Check the Cover Periodically: Throughout winter, inspect the cover for any sagging or debris accumulation. This maintenance keeps your pool safe and clean.

By draining and covering your pool correctly, you ensure it’s protected and ready for reopening in the spring.

Maintenance Tips For Spring Reopening

Spring reopening of your above ground pool requires careful attention, particularly to the sand filter and overall pool preparation. Follow these tips for a successful start to the swimming season.

Inspecting The Sand Filter

Inspecting the sand filter ensures proper functioning. Begin with the following steps:

1. Check for Damage: Look for cracks or leaks in the filter housing. Ensure all connections are secure.
2. Clean the Filter: Rinse the sand with water to remove any accumulated dirt or debris. This process enhances filtration efficiency.
3. Replace Sand: If the sand appears discolored or clumpy, replace it. Use the correct type of sand specifically made for pool filters.
4. Examine Valves: Inspect multiport valves for wear or damage. Replace any damaged parts to maintain proper operation.

Preparing The Pool For Use

Preparing the pool for use involves several essential steps:

1. Remove the Cover: Carefully take off the pool cover, ensuring no debris falls into the water.
2. Clean the Pool: Skim leaves and dirt from the surface. Vacuum the pool floor to eliminate settled debris.
3. Balance Water Chemistry: Test the water for pH, alkalinity, and chlorine levels. Adjust the chemicals to maintain safe swimming conditions (pH levels between 7.2-7.8).
4. Fill the Pool: If needed, add water to the proper level, ideally around the mid-skimmer height.
5. Start the Filter: Turn on the sand filter and run it for at least 24 hours to circulate water and evenly distribute chemicals.
6. Check for Leaks: Monitor the pool and filter system for any leaks after startup. Address any issues immediately.

Properly following these maintenance steps will help ensure your pool is ready for a fun and enjoyable swimming season.
