Why Does A Pool Lose Water In The Winter? [Expert Guide!]

Spread the love

A pool is a wonderful addition to any home, providing the perfect opportunity for relaxation and enjoyment. But it’s essential that you know how to look after your pool so that it can continue providing these benefits.

It’s not unusual for pools to become polluted, especially if they are not maintained correctly. But with some basic knowledge you can ensure that your pool stays crystal clear all year round.

Let’s explore the reasons why your pool may see a dip in the winter, as well as how you can stop this happening.

Too Many Leaves On The Trees

If there are heavy leaves on the tree above your pool, they will block the sunlight that normally helps maintain a stable temperature in your pool. Unfortunately, this can also result in your pool seeing some pretty significant dips in its water level during the winter months. If this happens regularly, it could mean you’ll need to invest in a submersible pool pump to ensure it stays topped up throughout the year.


Light rainfall, especially in the winter, can cause your pool to see some serious drops in its water level. This is because when it comes down to it, water just wants to be at its regular place. Since water cannot travel through pavement or soil, it will often find its way to the lowest point near to where it can settle. Rainfall in the summer can be just as problematic, as the heat is usually what drives the water towards the surface. You can reduce this by keeping the gutters on your roof clean and removing any debris that may be blocking the downpipes. Keep an eye out for any cracks or gaps in your plumbing too, as these could mean there’s been a serious incident in the past that you are now paying for.

Frozen Ground

When the ground is hard frozen, you cannot use your pool outdoors without risking a tragic accident. To avoid this, install a submersible pool pump and ensure that it is constantly supplying your pool with fresh water. If the ground is particularly hard, you may need to put an insulation layer on the pool surface to keep the water at the right temperature all year round. Once the ground thaws at the beginning of the season, you can remove the insulation and enjoy your pool without any problems.

Falling Snow

Falling snow is another common cause of minor pool flooding. But while this may not seem like a problem, if you have children or domestic animals around, you may want to keep an eye on how quickly they disappear into the snowdrifts. This is because snow can quickly turn into ice on the surface of your pool, especially if the temperature is below freezing. If you are worried about your pool ice forming, you can add some hot-tubs to the equation. These are silicon discs which are interlocked with metal wiring and can heat fresh water quickly. You can also use a heat lamp to melt the ice in your pool at night.

Dust And Pollution

It’s amazing how much dirt and pollution can accumulate in just a few months from leaves, dust and pet dander. This is why it’s important to keep your pool clean at all times. To ensure this, wash down the walls and floors with a hose regularly, change the filter fabric and chemical balance of the water every three months, and ensure there are no leaves or other organic matter on the surface of the water. If you have a fountain in the center of your pool, make sure you clean it every day with a brush and hose to keep the water nice and clear.

Leaves On The Pool Equipment

If there are leaves on the surface of your pool equipment, such as the filter or pump, this will clog them up and cause serious problems. To keep your pool equipment looking new, wash it every two weeks with a garden hose and leave it outside to air dry. Dry equipment and clean water are essential to keeping your pool in good condition and preventing nasty accidents from happening.

Frostbuild-up On The Glass

Frost build-up on the glass of your pool is another common cause of minor pool flooding. This occurs when the air temperature is below freezing and large amounts of water are present, creating a thick layer of ice on the panes of glass that cover your pool. To prevent this, make sure the panes of glass remain clean by removing any dirt or mold from the area around the edges. You can also use small balls of aluminum to remove this build-up quickly and easily before it causes any significant damage.

Leaks In The Wiring

Leaks in the wiring are a common cause of minor pool flooding. This occurs when rainwater seeps into the electrical sockets and contacts which power your pool pumps and lighting. To stop this from happening, shut off the power to your pool at night and check for any leaks before you use it. You can fix these with some waterproof electrical tape or silicon electrical tape, which is more reliable in the long run if you ask us.

Improper Maintenance

Proper maintenance can prevent most of the problems mentioned here. Make sure you have checked all of the equipment before use and cleaned it thoroughly after use. Wipe down the equipment with a clean cloth or dry paper towels when it comes into contact with water or dirt. Regularly change the filter fabric and chemical balance of your water to ensure it stays fresh and clean, and make sure the temperature is correct by either adding more heat to it or removing some. If you suspect any problems, get in touch with the experts at Waterwise Pools straight away so they can help diagnose and fix the issue. Proper maintenance can help prevent most of the problems experienced by pool owners, making it a cost-effective and reliable way to ensure your pool provides plenty of fun and relaxation for many years to come.
