Winter maintenance - Periodic removal of debris and removal of water on the covers surface will greatly decrease your pool opening time and efforts. If you have a sump hole on your pool deck, don't forget to check and pump it down to prevent your liner from floating up in the spring.


Every pool is unique and may have additional features and equipment not outlined in this guide. Winterizing your pool properly is important to preventing damage over the winter from freezing. If you are uncertain about how to winterize your pool equipment or would prefer to have PoolBoy manage your pool closing, give us a call and we'll schedule a closing date just right for you.


*Ensure water is de-chlorinated and meets levels outlined by your municipality before disposing of wastewater
