Why Winterizing Your Pool is Important

Winterizing your backyard oasis is a critical part of seasonal pool maintenance.

Here’s why:

Protecting Your Pool from Physical Damage

When the temperature drops, the water in your pool can freeze, and that’s when the real trouble starts. Frozen water expands, which can cause your pool’s tiles to crack, your pipes to burst, and your pump to fail. Proper winter pool service ensures all water is properly drained or treated so you don’t end up with expensive repairs come spring.

Maintaining Chemical Balance Over Winter

Leaving your pool unattended throughout the winter can lead to chemical imbalances, leading to scaling, corrosion, and other issues that are difficult to fix. Winter pool maintenance entails balancing your pool’s chemicals, including pH, alkalinity, and chlorine levels, before closing so it stays in top shape all winter long.

Protecting Against Algae and Bacteria

The last thing you want when reopening your pool in the spring is to find it contaminated with algae and bacteria. Proper chemical treatment and covering up the pool before closing ensures it stays clean. This way, you can avoid the costly and time-consuming process of dealing with a pool filled with algae or bacteria after reopening it in spring.

Reducing Winter Maintenance and Going Green

By shutting down your pool’s electrical systems, such as the filtration, pump, and heater, you drastically reduce electricity usage during the colder months. When your pool is winterized properly, the water remains clean and algae-free, meaning you won’t have to drain and refill it in the spring due to stagnation and contamination.

Lastly, by taking care of your pool equipment and covering your pool, you protect your pool gear from the harsh winter conditions. This prolongs the life of your equipment and lowers the need for replacements. That, in turn, minimizes the environmental impact associated with manufacturing and disposing of pool components.

Supplies Needed for Winter Pool Closing

Let’s see what supplies you need to close your pool for winter.

Having the right equipment at hand will make winter pool maintenance smoother and ensure your pool is well-protected throughout the winter months.

Here’s the list of essentials:

Pool Cover: A durable, high-quality cover that fits your pool to keep out debris and prevent water evaporation.
Winterizing Chemicals: This includes algaecides, chlorine tablets, and winterizing chemicals like calcium chloride to maintain water balance and sodium bicarbonate to adjust alkalinity levels and prevent algae growth.
Pool Pump and Filter Plug: To keep water out of your pump and filter and prevent freezing damage.
Siphon Hose: The hose reduces the water level by placing one end of the siphon hose in the pool and the other end outside at a lower elevation.
Automatic Water Leveller: This device automatically shuts off water flow once the desired pool level is reached, ensuring proper water levels during pool closing.

A Blower or Air Pump: This is for blowing out water from the pool’s plumbing lines to prevent freezing and damage.
Winterizing Kit: Often includes plugs, caps, and other tools specifically designed for winterizing your pool’s equipment and plumbing.
Skimmer Basket Cover: To prevent debris from entering the skimmer and clogging it during the winter.

How to Close Your Pool for Winter

Winterizing an inground or above-ground pool requires careful planning and diligent execution. Let’s walk through the steps to ensure your pool is winter-ready.

Clean Your Pool Thoroughly Clean your pool thoroughly before you start the winterizing process. Remove any debris from the water and clean the walls and floor. Use a pool vacuum for thorough swimming pool cleaning and ensure all dirt and leaves are gone. This step is crucial as leftover debris can lead to staining and algae growth during the winter months.
Balance the Water Chemistry Next, balance your pool’s chemistry. That includes adjusting the pH, alkalinity, and chlorine levels to their optimal ranges. Proper chemical balance helps prevent corrosion and scaling during the off-season. Make sure to test the water and add the appropriate chemicals to stabilize these levels. This step is essential for both inground and above-ground pools.
Lower the Water Level: When it comes to winterizing inground pool, you must lower the water level below the skimmer line. That way, water cannot enter the skimmer and freeze. For above-ground pools, you might need to lower the water level by just a few inches, depending on the type of cover you use. Always refer to your pool construction specifications and manufacturer guidelines for proper recommendations.
Blow Out and Plug the Plumbing: Use a blower or air pump to blow out any remaining water from the pool’s plumbing lines. This prevents water from freezing in the pipes and causing them to rupture. Once the lines are clear, install winterizing plugs to seal the plumbing. This step is particularly important for inground pools due to their complex plumbing systems.
Add Winterizing Chemicals: Add winterizing chemicals to the pool water. These typically include algaecides and winterizing tablets. These chemicals help prevent algae growth and maintain water clarity through the winter months. Ensure you follow the instructions on the chemical products for the right dosage.
Install the Pool Cover: Place a high-quality pool cover over your pool. For inground pools, use a solid cover to keep out debris and protect the water. For above-ground pools, a good cover will help keep out leaves and other contaminants. Make sure the cover is secured tightly to prevent it from blowing away or allowing debris to enter.
Protect Your Pool Equipment Winterizing your pool equipment is also an essential step of pool servicing. Remove and clean the filter, pump, and other components. Store them in a dry, sheltered place if possible.

Special Considerations for Indoor Pools

If you have an indoor pool, you might not need to go through the entire winterizing process. Some care is still necessary, however. Indoor pools generally don’t face the same risks of freezing and heavy debris.

But here’s what you must keep in mind:

Maintain Water Quality: Regularly test and balance the water chemistry to prevent issues like scaling and corrosion.
Inspect and Clean: Periodically check and clean the pool and its equipment to keep everything in good working order.
Monitor Humidity Levels: Ensure proper ventilation to manage humidity levels and prevent damage to the pool structure and surrounding areas.
