Winterizing Your Pool: A Complete Step-by-Step Guide

As the temperatures begin to drop and the leaves start to fall, it’s time to think about properly closing and winterizing your pool for the colder months ahead. For pool owners in the Northeast, winterizing isn’t just about keeping your pool clean and ready for next season—it’s about protecting your investment and preventing costly repairs. If you don’t take the time to winterize your pool, freezing temperatures can wreak havoc on the plumbing, equipment, and pool structure itself.

Whether you’re a seasoned pool owner or a first-timer, this complete step-by-step guide will walk you through the process of winterizing your pool the right way.

Why Is Winterizing Important?

Winterizing your pool is essential to protect it from the damage that can occur when water freezes and expands. Without proper care, you could be left dealing with cracked pipes, damaged filters, and even structural problems. Winterizing also ensures that your pool will be ready to open smoothly when the warmer weather returns, with clean water and minimal hassle.

Step 1: Clean Your Pool Thoroughly

Before you begin the winterization process, it’s crucial to start with a clean slate. Follow these steps:

  • Skim the Surface: Remove leaves, insects, and other debris from the pool surface using a skimmer.
  • Brush the Walls and Floor: Use a pool brush to scrub the walls, floors, and corners to prevent algae growth.
  • Vacuum: Whether you use a manual or automatic pool vacuum, make sure the pool is spotless.
  • Clean the Filter: Depending on your filter type (sand, cartridge, or DE), backwash or clean it thoroughly to remove any built-up dirt or debris.

 Step 2: Balance Your Pool’s Chemicals

Proper water chemistry is key to maintaining your pool throughout the winter months. Even though the pool won’t be in use, balancing the chemicals helps prevent algae growth and protects the pool’s surfaces.

Head to your local pool store for the best testing and balancing recommendations.

Step 3: Add a Winterizing Chemical Kit

A winterizing chemical kit is specifically designed to maintain water quality during the cold months. These kits typically include:

  • Algaecide: Prevents algae from growing during the off-season.
  • Winterizing Shock: Keeps the water clean and prevents cloudiness.
  • Stain and Scale Preventer: Protects the pool surfaces and equipment from staining or scaling.

Follow the instructions on the winterizing kit for your pool’s size and type to ensure proper protection.

Step 4: Lower the Water Level

In areas where temperatures drop below freezing, it’s important to lower the water level to prevent water from entering the pool plumbing and freezing.

  • Inground Pools: Lower the water level to about 4-6 inches below the skimmer or tile line. Pools with mesh covers should be lowered 16-18 inches to allow for rain or snow melt to refill the pool by spring.
  • Above Ground Pools: Lower the water just below the skimmer, or use a pool skimmer cover plate to block water from entering.

Step 5: Drain Pool Equipment and Lines

Freezing water inside your pool equipment or plumbing lines can cause costly damage. To prevent this, it’s essential to remove all water from the system.

  • Blow Out the Lines: Use an air compressor or shop vacuum to blow air through the pool lines, forcing water out of the pipes. Once the lines are dry, plug them with winterizing plugs.
  • Drain Equipment: Be sure to drain water from the pool pump, filter, heater, and chlorinator. You may also need to remove drain plugs or open valves to allow excess water to escape.
  • Store Equipment: If possible, remove any small, portable pool equipment and store it indoors to protect it from freezing temperatures.

Step 6: Cover the Pool

A high-quality pool cover is your best defense against winter weather. It keeps out debris, prevents algae growth, and stops water from accumulating in the pool.

  • Safety Cover: A mesh or solid safety cover is an ideal option for inground pools. It’s secure and prevents children or pets from falling into the pool during the winter months.
  • Winter Cover: For above-ground pools, a winter cover will keep out leaves and debris, helping to maintain water clarity for next season.

Make sure your cover is tight and secured to avoid wind damage or debris entering the pool. You can use water tubes or cover clips to secure it in place.

Step 7: Monitor Your Pool Throughout the Winter

Just because your pool is closed doesn’t mean you should forget about it. Periodically check your pool cover and equipment throughout the winter months to ensure everything is intact and no damage has occurred due to weather or debris buildup.

  • Clear Off Debris: Remove heavy snow or leaves that may accumulate on top of the cover.
  • Check Water Levels: If water builds up on top of the cover, use a cover pump to remove excess water.

Successful Closing!

By taking the time to properly winterize your pool, you can avoid costly repairs and make your spring pool opening a breeze. With the right preparation, your pool will stay in top shape and be ready for you and your family to enjoy as soon as the warmer weather returns.
