When winterizing a pool, what should be done to the pool piping?

Draining and sealing the pool piping during winterization is essential to preventing damage from freezing water. When water in the pipes freezes, it expands, which can lead to cracks and other serious damage to the plumbing system. By draining the pipes to remove any residual water and sealing them effectively, you create a safeguard against freezing temperatures. This practice helps maintain the integrity of the pool's plumbing for the next swimming season, ensuring that it operates smoothly without the need for costly repairs.

Other approaches such as insulating do not offer complete protection and would not completely eliminate the risk of ice formation inside the pipes. Leaving the pipes filled with water may lead to severe damage during winter months, and simply leaving them as is exposes them to the same risk of freezing. Thus, draining and sealing the piping is the most effective method to ensure the longevity and functionality of the pool system.
