How to Close Your Pool for Winter

The weather is getting colder and the leaves are starting to change. Fall is certainly on its way. If you have a pool, you know exactly what that means. It’s time to close your pool for winter. Before you begin this process, we’ll explain how to close a pool for the winter, step by step.

Begin Winterizing

Start this process one week before actually closing it by using chemicals to prevent algae.

Clean Your Pool

When you’re finally ready close your pool, start by cleaning your pool and removing any debris. This will help prevent algae growth and make reopening your pool in the spring much easier.

Prevent Freezing

Winter weather will cause your pool water to freeze. To help with this problem, drain your pool below the freeze line (below the pool’s inlets).

Balance Your Pool

When preparing your pool for the winter, make sure to balance your pool chemicals. Use a testing kit to make sure your alkalinity is between 80-120 ppm and pH is between 7.0-7.4.

Shock & Chlorinate

Shock your pool and chlorinate it to kill any bacteria that may stick around during the winter months.

Backwash Your Filter

Allow the pump to run a full cycle, then backwash and chemically clean your filter.

Drain Pool Lines

Keep your pool lines from freezing during the winter by draining them and filling them with antifreeze. This will keep your pipes from freezing and bursting during the following months. This is only for areas that freeze during the winter.

Shut Off Pumps and Heaters

Since you won’t be using your pool until next spring, turn off all pumps, heaters, and other electrical equipment, including shutting of their power at the circuit breaker.

Cover Pool

Once everything else has been taken care of, cover your pool with a secure pool cover.
