What about the pool anitfreeze which was put in pipes when closing Does this fileter into water opening pool?

When closing a pool for the winter, it is common to add pool antifreeze to the water to prevent pipes from freezing and bursting during cold weather. This antifreeze is typically made of propylene glycol, which is a non-toxic chemical that is safe for use in pools.

When opening a pool in the spring, it is important to thoroughly drain and rinse the pool water to remove any residual antifreeze. This can be done by connecting a hose to the drain valve at the bottom of the pool and allowing the water to drain out. Once the pool is empty, it should be rinsed several times with fresh water to remove any remaining antifreeze.

It is important to note that pool antifreeze should never be added directly to the pool water. It should only be added to the pipes when closing the pool. If antifreeze is added directly to the pool water, it can cause damage to the pool liner and other pool components.

If you are unsure about how to properly close or open your pool, it is always best to consult with a pool professional.
