Does the skimmer flap need to be removed when closing pool for winter?

Yes, the skimmer flap should be removed when closing a pool for winter. Removing it helps prevent water from freezing and causing damage to the skimmer and Plumbing lines. Additionally, it allows for proper water drainage, reducing the risk of ice expansion that could crack the skimmer. Always ensure the skimmer is properly winterized to protect your pool equipment.
