Getting Started: Preparing Your Above Ground Pool for Winter

Closing your above ground pool for the winter might seem daunting, but with the right steps, it's manageable. Proper winterization prevents costly repairs and ensures your pool is ready for splashing next spring. This guide will walk you through each essential step. Let's get started!

1. Cleaning Your Above Ground Pool

Before you begin the winterizing process, thoroughly clean your pool. This crucial step removes debris that could damage your pool or equipment during the winter months.

Remove leaves and debris: Use a leaf net or pool vacuum to remove all visible debris from the pool. Don't skip this – even small amounts of debris can cause problems.
Brush the walls and floor: A thorough brushing removes algae and other clinging matter. Pay close attention to the waterline.
Vacuum the pool: Vacuum all the debris you've loosened. Consider using a pool vacuum with a debris bag to make the process easier.

2. Balancing Your Pool Water Chemistry

Correct water chemistry is essential to prevent damage over the winter. Imbalances can cause corrosion, staining, and algae growth.

Test your water: Use a reliable test kit to check the levels of chlorine, alkalinity, and pH. Your local pool supply store can help you interpret your results.
Adjust chemicals: Adjust your water chemistry according to the test results. Follow the instructions on your chosen pool chemicals carefully. Aim for slightly higher than normal levels of chlorine and slightly higher alkalinity.
Consider a winterizing algaecide: Add a winterizing algaecide to help prevent algae growth during the off-season.

3. Lowering the Water Level

Lowering the water level is crucial to prevent pressure damage to your pool walls and equipment during freeze-thaw cycles.

Check your manual: Consult your pool's owner's manual for the recommended water level. This usually involves lowering the waterline below the skimmer and return jets.
Use a submersible pump: A submersible pump is the easiest way to lower the water level quickly and efficiently. You can also use a siphon.
Important Note: Be careful not to lower the water level too much, as this could damage the pump.

4. Cleaning and Storing Equipment

Properly cleaning and storing your pool equipment is essential to its longevity.

Clean the filter: Thoroughly clean or replace your filter cartridges or grids. A dirty filter can harbor bacteria and algae.
Drain and store hoses: Drain and store all pool hoses and equipment in a dry place to prevent damage from freezing.
Winterize your pump: Follow the manufacturer's instructions for winterizing your pool pump. This often involves draining the pump and adding antifreeze.

5. Protecting Your Pool

Adding a pool cover provides an additional layer of protection against debris and freezing temperatures.

Choose the right cover: Select a winter pool cover designed for above-ground pools. Consider a safety cover if you have children or pets.
Secure the cover: Properly secure the cover to prevent it from blowing away in windy conditions. Use appropriate weights or anchors.
Air pillows (optional): Air pillows placed on top of your cover can help prevent water from accumulating and freezing on the cover.

6. Adding Antifreeze to Your Plumbing

This step protects your plumbing system from damage caused by freezing temperatures.

Identify all plumbing: Locate all pipes and components that might freeze.
Use RV antifreeze: Use RV antifreeze specifically designed for plumbing systems; never use automotive antifreeze.
Pour antifreeze into the system: Carefully pour the antifreeze into your plumbing system, following the manufacturer's instructions.

How to Close an Above Ground Pool: A Step-by-Step Guide (Summary)

Clean: Thoroughly clean the pool, vacuuming and brushing.
Balance Chemicals: Adjust chlorine, alkalinity, and pH levels; add algaecide.
Lower Water Level: Reduce water level below skimmers and returns.
Clean and Store Equipment: Clean filters, drain hoses, and winterize the pump.
Cover the Pool: Secure a winter pool cover with weights or anchors.
Add Antifreeze: Pour RV antifreeze into plumbing to protect against freezing.

Spring Startup: Getting Your Pool Ready

When spring arrives, remember to reverse these steps for opening your above ground pool! This will ensure your pool is ready for a summer of fun. Always consult your owner’s manual for the most accurate instructions specific to your model of pool and equipment. Enjoy your winter, and happy swimming next year!
