How To Maintain A Pool During Winter

As the colder months approach, many pool owners may assume it's time to forget about their pools until spring. However, proper winter pool maintenance is essential for keeping your pool in top condition. 
Failing to prepare your pool for winter can lead to costly damage, such as cracked pipes, algae build-up, or broken equipment. In this guide, we’ll walk you through the key steps on how to maintain a pool during winter to ensure a smooth opening when the warmer months return.

Clean the Pool Thoroughly

Before closing your pool for the winter, it’s crucial to give it a deep clean. Any debris, leaves, or dirt left behind can lead to algae growth or stain your pool surface. Skimming the surface, vacuuming the pool floor, and brushing down the walls to remove any lingering particles will help keep your pool in pristine condition. It’s also essential to clean your pool’s filters and drains, making sure they are free of any blockages. Starting with a clean pool will prevent unwanted problems during the winter months and make spring opening much easier.

Balance the Water Chemistry

One of the most important steps in maintaining a pool during winter is ensuring the water chemistry is properly balanced. Imbalanced water can cause scaling, corrosion, and algae growth, potentially damaging both your pool and equipment. To prevent this, make sure your pool’s pH is between 7.2 and 7.6, while alkalinity should range from 80 to 120 parts per million (ppm). Additionally, the calcium hardness should be kept between 200 and 400 ppm to avoid potential scaling. Many pool owners also choose to add a winterising chemical kit, which often includes algaecide, a stain prevention treatment, and a chlorine shock to keep the water clear and safe throughout the off-season.

Lower the Water Level

If you live in an area prone to freezing temperatures, lowering the water level is a key step in protecting your pool. When water freezes, it expands, which can cause damage to your pool’s tiles or plumbing system if the water level is too high. Typically, it’s recommended to lower the water level just below the skimmer, but it’s always a good idea to consult your pool’s manufacturer guidelines or a professional to ensure you’re doing it correctly. Proper water levels will help prevent freeze-related damage.

Drain and Protect Pool Equipment

Freezing temperatures can wreak havoc on your pool’s equipment if not properly prepared. To prevent this, drain and store any equipment that could be affected by the cold. The pump should be either removed and stored, or at least drained of any water. Similarly, your pool’s heater must be drained to avoid any freezing inside the unit. The filter should also be cleaned and drained thoroughly. Lastly, it’s highly recommended to blow out any remaining water from the pool’s plumbing lines using an air compressor, as this will ensure no water is left inside to freeze and damage the pipes.

Install a Quality Winter Pool Cover

A high-quality winter pool cover is one of the best investments you can make to protect your pool during winter. The cover will help keep debris, leaves, and dirt out of the pool while also maintaining the water temperature and preventing accidents. When selecting a cover, make sure it fits your pool tightly and is sturdy enough to withstand the weather conditions in your area. For added protection, using a pool cover pump to remove excess water or snow that accumulates on top of the cover is a smart move, as it prevents the cover from sagging or tearing underweight.

Open Your Pool Early

Once winter has passed and temperatures begin to rise, it’s best to open your pool early. Waiting too long can result in algae blooms or other problems that could have been avoided with a timely reopening. Opening your pool early will allow you to address any potential issues before they escalate, ensuring your pool is ready for use when the warm weather returns.
