Who needs to winterize their pool? Why?

If you receive a consistent amount of snow, sleet, or temperatures around or below 32°F or 0°C, you need to winterize your pool. If you do the upfront work preparing your pool and equipment for winter, your pool water will be in better condition come springtime.

What does it mean to "winterize my pool?"

You are preparing your pool equipment, water and surrounding area for cold, winter weather.

Pool professionals call pools of this region "Snowbelt Pools" because these pools close for the winter.

If you want to get started before your appointment, consider the following:

1. Give your pool a deep clean

Drop your robotic pool cleaner in the pool so it can brush off any deposit hanging around the pool walls. If you have a pool brush, thoroughly scrub the side of your pool to reduce the chance of black algae and scaling on your pool walls.

2. Check your pool water chemistry

Make sure your pool water is balanced before winterizing your pool. Stabilizing your pool water will ensure you don’t have more significant problems like algae bloom or scaling when you remove your pool cover in springtime.

Before closing your pool, always shock the water before adding winterization chemicals.

3. Turn off your pool equipment

Remove booster pumps, pool cleaners, any accessories you might have in the pool. Keep your automation system, pool pump and filtration system running until your pool professional arrives. They will ensure they are dried and winterized correctly.

4. Find space for your pool equipment

Make room for your pool equipment in a dry space. Ideally, somewhere that doesn’t get below 40°F degrees. Many people put their equipment in their shed or in the back corner of their garage to aid in the protection of the freezing temperatures outside don’t reach the pool equipment.

5. Get in touch with your pool professional

You’ll want to ensure you are on your pool professional’s schedule so they can help you winterize your pool. They have pool closing services to ensure your pool is safe from the winter elements.

Your Pool Professional Will Help With:

1. Lowering the pool water level

Reducing the level of your pool water helps with freeze protection and the chances of an overflow.

2. Draining and removing equipment

Your pool expert will remove water from your pool equipment like pool pumps, filters and sanitizers to reduce the chance of equipment damages.

Don’t forget to remove the plugs.

3. Winterizing pool lines and adding winter equipment

Your pool expert will blow your pool equipment lines, so no water is left to reduce the chances of frozen or damaged equipment.

Typically, pool experts will add a gizmo or plug to your skimmer to help protect your pool pipes from frozen water getting stuck in the pipes.

4. Adding a winter cover

  • Confirm there are no holes or abrasions to the pool cover.
  • If you have an inground pool, consider adding water bags to secure your winter pool cover.
  • Install an air pillow for an above ground pool.

An air pillow helps relieve the pressure from the accumulation of rain, snow and ice, which may and can prevent damages to your pool cover, liner and walls. Place the air pillows in the middle of the pool. If you have a large pool, you may need two or more air pillows to prevent snow or ice from damaging the pool's structure.

During the winter

If you can access your pool and release a corner of the cover, consider checking your chemical levels and if needed, add chlorine once a month to keep your chlorine residual intact. It's imperative to maintain your chlorine levels because chlorine diminishes overtime, and it can help combat dirt and grime in the pool. To keep your pool water in check in the winter months, keep your water at 3 PPM.

What is residual pool?

It’s your pool water measured at depth, volume and size when water flow stops. Keeping your pool water as close to a metric of 3 PPM as possible will help ensure the chlorines sanitation effectiveness is working at maximum strength.
