Here are the steps to winterize a swimming pool. The method described below whereby pool plumbing pipes are blown out and sealed first was most widely performed in New England and the East coast of the US. It is now becoming common to perform this method throughout the US and in other countries.
A slight variation of these steps can be performed where the pool is partially drained and an anti-freeze product is added to the lines instead of blowing out the lines and sealing them. Some of the trade-offs with that slightly different method are discussed below when that step is outlined.
NOTE: A swimming pool winterization of this type is rarely done in Texas or some of the other southern states because the weather typically does not stay below freezing for enough days to freeze the ground to a depth where there are benefits from blowing out the lines or having anti-freeze in them. We have a separate post about how most pool owners commonly deal with how to winterize a swimming pool in Texas.
