How to Properly Close Your Pool for Winter Step-By-Step

How to close my pool

Pool-closing time is a sad time of the year for everyone. It marks the end of summer fun and the beginning of colder weather.

It’s understandable that many people choose to keep their pools open longer, as an open pool is much more appealing than a closed one. But if it’s too cold to swim and there are leaves and other debris falling into the pool, you may want to close it. In this article, we explain the best way to winterize your outdoor pool.

Why closing a pool (the right way) is important

The two main reasons why it’s important–and necessary here in Canada–to close your pool is to:

  • Protect it from damage due to freezing temperatures
  • Keep it as clean as possible for the next season
  • Keep the area safe for kids or animals

How to Prepare Your Pool For Winter

Step 1. Prep your pool water

Before you close your pool, it’s important to make sure your pool water will stay algae-free and healthy throughout the winter.

Try adding in a phosphate remover or other anti-algae solution to help keep the algae out.

Step 2. Thoroughly clean your pool

Brush and vacuum your pool floors and walls to prevent algae and ensure an easier spring opening.

Step 3. Check your water levels

The water level needs to be lowered just below the jets. This enables you to blow out the lines.

Once the lines are clear of water, you need to plug the returns with winterizing plugs to ensure the water does not get back into the lines.

To properly support your winter cover, your water level should never exceed a depth of 18” from the deck. The equipment will also need to be winterized properly to ensure there is no water is left in the pump, filter and any other equipment you have.

Step 4. Balance pool water pH
