If not properly protected, freezing conditions can damage to your swimming pool’s equipment and plumbing. When water freezes and expands in pipes, they can burst – destroying both your pipes and possibly your decking. If possible, you should keep your pump running during freezing conditions so that the water is constantly moving – preventing it from freezing.
You should always lower the water level of your pool before a deep freeze. If your pool is still frozen, do not attempt to lower the water level until the ice and snow melts. This may cause damage to your pool cover or liner. A good way to lower the level is by placing a small pump in the pool skimmer.
It is always best to close your pool for the winter if you live in areas that are prone to freezing temperatures. In warmer climates, keep the pool pump running as you normally would.
