It's not the freezing water in your pool that should worry you. It's the water you can't see.
As Southern Ontario heads toward colder weather, one of the biggest risks to an improperly winterized pool is water left inside plumbing lines and equipment.
When trapped water freezes, it expands. That pressure can damage pipes, fittings and other vulnerable components, potentially leaving homeowners with expensive repairs when spring arrives.
That's why a proper pool closing involves much more than putting on a cover.
Pristine Pools provides professional pool closing and winterization services throughout Guelph and Wellington County.
Enjoy the Thanksgiving long weekend, and if your pool is still open, make sure it's properly prepared before freezing weather arrives.
