How to Close Your Pool Without Draining Water


As the warm weather comes to an end, so nears the end of the swimming season, and it becomes time to close your pool and prepare it for winter—and the dreaded draining. But, what if you could close your pool without draining water? Here’s what you should know about preparing your pool for winter without draining it!

Let’s face it, your pool and the various pieces of equipment needed to run and maintain it can be expensive! Without taking the necessary steps before winter arrives, you could be facing some costly repairs and replacements in the spring before you can enjoy your pool once again. To help you along the way, here are some super simple steps you can take for a stress-free, easy pool closing. Here’s what you’ll need:

  • Winterizing Chemical Kit
  • Pool Shock
  • Skimmer Cover Plate
  • Return Fitting Winter Plug
  • Air Pillow
  • Winter Pool Cover

A winter cover pump is generally recommended. This helps to keep the excess water from collecting on the cover during winter. If water accumulates it can stress or tear your pool cover and cause even more damage to your pool.


Steps to Close Your Pool Without Draining

Preparing for Closing

One week before closing, you’ll want to add a phosphate remover to your water. This will prevent algae from making a home in your pool. You’ll also want to give your pool a thorough cleaning. Be sure to brush and vacuum your pool to prevent algae growth and make opening your pool in the spring even easier.

Water Management

If you live in a region with freezing temperatures, you should lower your water level to 4-6 inches below your in-wall-skimmer. For those in non-freezing regions, your water level should be nearly overflowing and kept filled right to the top.


Using a testing kit, measure your water chemistry. Your alkalinity should range between 80-120 ppm and your pH levels should be no higher than 7.6 and no lower than 7.4.


To get rid of any lingering bacteria, it’s important to chlorinate and shock your pool before closing. This will ensure your spring opening goes smoothly.

Filters and Air Lines

To make sure your pool equipment endures the winter season, it’s important to backwash your filter and drain all your pool lines. In freezing regions, add antifreeze to your pool lines to prevent ice damage.

Cover Your Pool

Once you have prepared your pool for closing, it’s time to cover it. You can use a safety cover, a leaf net, or preferably a winter cover. To prevent water accumulation on the top of your pool cover, inflate an air pillow and place it in the center of the pool before covering.

During the winter season, you’ll want to routinely check your water chemistry each month with a simple testing kit to ensure your chemical balance is ideal.

With these simple steps, you can enjoy a stress-free pool closing without draining, and an even easier spring opening.
