Clean backyard pool with clear water

Mistake 1: Closing With Bad Chemistry

Closing a pool with high pH, high metals, or an active algae problem sets you up for stains and a rough spring. Balance before you winterize so the water is stable while it sits.

Mistake 2: Leaving Water in Lines and Equipment

Freeze damage is expensive and preventable. The goal is to get water out of vulnerable plumbing and protect returns and skimmers appropriately for your setup.

If you are not confident in your blowout and plug process, this is the moment to bring in a pro. One missed low spot can crack fittings.

A Clean Close Saves Hours Later

Brush, vacuum, clean baskets, and clean the filter before you shut down. The cleaner the pool is when you close, the less time you spend fighting mess on opening day.
