5 Simple Steps To Winterize An Inground Pool

As the temperatures begin to drop and the leaves start to change color, it’s time to start thinking about winterizing your inground pool. Winterizing your pool properly is essential to protect it from damage caused by freezing temperatures and ice. Failure to winterize your pool can lead to cracked pipes, damaged pool liners, and other costly repairs. Here are the steps on how to properly winterize your inground pool.

First, you need to clean the pool thoroughly. This includes vacuuming the pool to remove any dirt or debris, as well as brushing the sides and bottom of the pool to remove any algae or mold. Once the pool is clean, you need to balance the water chemistry. This includes adjusting the pH level, alkalinity, and calcium hardness to the recommended levels. Balancing the water chemistry will help to prevent scaling, corrosion, and other damage to the pool and equipment.

Next, you need to lower the water level in the pool. The water level should be lowered to about 6 inches below the skimmer opening. This will help to prevent the water from freezing and expanding, which can damage the pool liner or sidewalls. The skimmer will also need to be winterized so the water can drain when it rains. Finally, you need to add a winterizing chemical to the pool. Winterizing chemicals help to prevent algae growth and scale formation during the winter months. Once the winterizing chemical is added, you need to run the pool pump for a few hours to circulate the chemical throughout the pool.

Proper Pool Cover Selection and Installation

Choosing the right pool cover and installing it properly are crucial for winterizing your inground pool. Here are the key considerations:

Types of Pool Covers

There are two main types of inground pool covers:

Cover Type	Pros	Cons
Solid Covers	Prevent debris and sunlight More durable than mesh covers	Heavier and more expensive Require a cover pump to remove water
Mesh Covers	Lightweight and affordable Allow water to pass through, reducing weight	Less durable than solid covers Can trap debris and algae growth

Cover Sizing and Installation

Measure the pool’s dimensions carefully and add 1-2 feet around the perimeter for overhang. Choose a cover that fits snugly but not too tightly. Follow the manufacturer’s instructions for installation, ensuring:

The cover is taut and secure with no sagging or wrinkles.
Water bags or weights are used to anchor the cover around the pool’s edge.
A cover pump is used to remove any accumulated water from solid covers.

Chemical Balancing for Winter Storage

Effectively winterizing your inground pool involves diligently maintaining its chemical balance to prevent damage and prolong its lifespan. Here’s a comprehensive guide to chemical balancing for winter storage:

1. Lower pH Levels

Lower the pH level to around 7.2-7.6. This prevents corrosion and etching of pool surfaces and equipment.

2. Maintain Chlorine or Bromine Levels

Keep chlorine or bromine levels between 1-3 parts per million (ppm) to continuously sanitize the water and prevent algae growth. Shock the pool with a higher dose of chlorine or bromine before closing to kill bacteria and impurities.

Chemical	Recommended Level (ppm)
Chlorine	1-3
Bromine	1-3

3. Adjust Alkalinity and Calcium Hardness

Maintain alkalinity between 80-120 ppm, which stabilizes pH levels. Adjust calcium hardness to 200-400 ppm to prevent scale formation and damage to pool surfaces.

4. Add Winterizing Chemicals

Add a winterizing chemical to prevent algae growth and protect pool surfaces. These chemicals typically contain algaecides, clarifiers, and scale inhibitors.

5. Test and Rebalance Regularly

Throughout winter, periodically test the water chemistry and rebalance as needed to maintain optimal levels. Check the pH, alkalinity, and chlorine or bromine levels.

Air Pillow Deployment for Ice Prevention

The deployment of air pillows on the surface of an inground pool is an effective method for preventing ice formation and subsequent damage to the pool structure and equipment. Air pillows are large, inflatable cushions that float on the water’s surface and create a barrier between the water and the cold air. This barrier helps to insulate the water and prevent it from freezing, even in extreme cold temperatures.

To effectively deploy air pillows, the following steps should be taken:

Choose the right size and number of pillows. The size and number of pillows required will depend on the size of the pool and the climate in which it is located. It is generally recommended to use one pillow for every 50 square feet of pool surface area.
Inflate the pillows to the proper pressure. Air pillows should be inflated according to the manufacturer’s instructions. The proper pressure will be indicated on the pillow’s label. Underinflation can reduce the effectiveness of the pillows, while overinflation can damage them.
Position the pillows strategically. The pillows should be placed in areas of the pool where ice is most likely to form, such as near the edges and around the skimmer and return jets. Pillows should be evenly spaced across the pool surface to ensure maximum coverage.

Pump and Filter System Removal

The first step in winterizing your in-ground pool is to remove the pump and filter system. This will prevent them from being damaged by freezing temperatures.

To remove the pump and filter system, follow these steps:

Turn off the power to the pump and filter system.
Close the valves on the inlet and outlet lines of the pump.
Disconnect the inlet and outlet lines from the pump.
Remove the pump and filter system from the pool deck.

Detailed Instructions for Step 4:

Step 1: Loosen the bolts that hold the pump and filter system to the pool deck using a wrench or socket set.
Step 2: Carefully lift the pump and filter system off the pool deck. Be sure to lift straight up to avoid damaging the connections.
Step 3: Place the pump and filter system in a protected area for storage during the winter.

Plumbing Line Draining and Blowing Out

As the temperatures start to drop, it’s time to winterize your inground pool. One of the most important steps is to drain and blow out the plumbing lines. This will help prevent the lines from freezing and bursting, which could cause costly damage.

Step 1: Turn Off the Pump and Filter

The first step is to turn off the pump and filter. This will stop the water from circulating through the plumbing lines.

Step 2: Open the Drain Plugs

Once the pump and filter are off, you need to open the drain plugs on the pool equipment. This will allow the water to drain out of the lines.

Step 3: Attach an Air Compressor

Once the drain plugs are open, you need to attach an air compressor to the blow-out port on the pool equipment. This will be used to blow the water out of the lines.

Step 4: Blow Out the Lines

With the air compressor attached, you can now blow out the lines. Start by blowing out the smaller lines first, such as the return lines. Then, move on to the larger lines, such as the main drain line.

Step 5: How to Blow Out the Main Drain Line

Blowing out the main drain line can be a bit more challenging than the other lines. Here are some tips:
– Use a high-powered air compressor.
– Insert the air hose into the main drain line as far as possible.
– Seal the opening around the air hose with a rag or duct tape.
– Blow out the line until all of the water has been removed.

Additional Tips

– If you have a lot of water in your lines, you may need to use a wet/dry vacuum to remove it before you can blow out the lines.
– Be careful not to overinflate the lines. If the lines are overinflated, they could burst.
– Once you have blown out all of the lines, you should close the drain plugs and turn off the air compressor.
