Best Tips for Closing Your In-Ground Pool for Winter
  • Opening Intro -

    Despite mid-September being the official start of the colder months, it wouldn't hurt to think ahead.

    This means winterizing your home and swimming pool.


Luckily, your pool is in-ground, so you won’t have to hassle with what feels like endless amounts of polyvinyl material. However, that doesn’t mean closing an in-ground pool is less work.

Here are some best tips and practices when closing your in-ground pool for the winter.

Start Winterizing Before Closing

You can start winterizing your pool a week before closing by adding phosphate remover to get rid of algae. Algae thrive in warm weather, so avoid closing your pool too early to prevent further growth.

Remove All Debris

Get rid of all algae-causing debris in your pool by using a brush and pool vacuum. You can also use a skimmer to pick up branches and loose leaves on the water’s surface.

Balance Chemistry

Measure your water’s balance using a test kit to check for high alkalinity levels. If pH levels are high, a Ph reducer such as muriatic acid or sodium bisulfate can regulate alkaline levels that could damage your pool.

Shock and Chlorinate

Pool shock works to oxidize ammonia, swimmer waste, and nitrogen compounds. You should shock your pool water days and ensure bacteria removal before you close it. You could do it during the daytime or the night before. 

Drain Lines and Add Anti-freeze

Draining pool lines are vital to prevent damaged pipes during winter. Most pool equipment items have a drain plug that allows water to drain out.

After draining the plumbing, remember to add anti-freeze to your pool’s system so you can protect it when the temperatures are harsh.

Install a Pool Cover

Protect your cool with a secure pool cover. There are plenty of options to choose from; however, different covers serve different purposes.

For example, a safety cover can provide the highest level of safety from storm debris and get anchored into the deck to ensure maximum security.
