Pool Winterizing: Water Level and Drainage

As the colder months approach, it's time to start thinking about winterizing your pool. Proper winterization is crucial to protect your pool from potential damage caused by freezing temperatures and ice. One important aspect of pool winterizing is managing the water level and drainage.

In this blog post, we will explore the importance of maintaining the correct water level and how to properly drain your pool for winter.

Why is water level important for pool winterizing?

Maintaining the correct water level in your pool is essential during the winter months. The water level should be lowered to a specific point to prevent any damage that can occur due to freezing temperatures. If the water level is too high, it can lead to ice expansion and potentially damage the pool walls or equipment. On the other hand, if the water level is too low, it can cause the pool cover to sag and potentially collapse under the weight of snow or debris.

How to determine the correct water level

The ideal water level for winterizing your pool is typically around 12 to 18 inches below the skimmer. This allows enough space for the water to expand when it freezes without causing any damage. However, it's important to consult your pool manufacturer or a professional to determine the specific water level requirements for your pool, as it may vary depending on the design and materials used.

Proper drainage techniques

Before draining your pool for winter, it's crucial to follow the proper drainage techniques to avoid any potential damage. Here are some steps to ensure a safe and effective drainage process:

  1. Turn off the pool pump and any other equipment connected to the pool.
  2. Remove any debris or leaves from the pool to prevent clogging during the drainage process.
  3. Attach a hose to the pool's drainage outlet and direct it away from the pool area to avoid any flooding or water damage.
  4. Open the drainage valve slowly to allow the water to flow out gradually. Avoid opening it fully, as it can create excessive pressure and potentially damage the pool's structure.
  5. Monitor the drainage process closely and ensure that the water is flowing smoothly.
  6. Once the water level reaches the desired level, close the drainage valve and disconnect the hose.

Remember, it's important to follow the specific instructions provided by your pool manufacturer or consult a professional to ensure the proper drainage technique for your pool.


Properly managing the water level and drainage is a crucial step in winterizing your pool. By maintaining the correct water level and following the proper drainage techniques, you can protect your pool from potential damage caused by freezing temperatures and ice. Remember to consult your pool manufacturer or a professional for specific instructions tailored to your pool's design and materials. With the right winterization techniques, you can ensure that your pool remains in excellent condition and ready for the next swimming season.
