How Far to Drain Pool for Winter – RMD Pool Service

When temperatures drop, do pools freeze in the winter? The short answer is yes, they can, and the potential damage is significant, especially if they’re not properly cared for during the colder months. Whether you have an inground or above-ground pool, frigid temperatures can cause severe damage to your pool’s equipment, liners, and overall structure. As pool experts at RMD Pool Services, we’ve seen how freezing water can wreak havoc on pools. But don’t worry—with the proper knowledge and pool maintenance, you can dodge costly repairs and keep your pool safe.

Let us share eight tips for protecting your pool from freezing so you’re ready for the cold months ahead.

 

Why Do Pools Freeze in the Winter?

Before diving into the tips, let’s address the big question: do pools freeze in the winter? When temperatures fall below freezing point (32°F or 0°C), the water in your pool can start to freeze, especially if it’s not circulating or maintained properly. Once ice starts to form, it expands, putting pressure on the pool structure, pumps, and filters.

While inground pools are more insulated by the ground, they can still freeze if left unattended. On the other hand, above ground pools are particularly susceptible to winter damage due to their exposed sides.

 

8 Must-Know Tips to Prevent Pool Freezing

1.   Keep Your Pool Pump Running In Freezing Temperatures

One of the most effective ways to prevent a pool freeze is to run your pool pump continuously when temperatures are near or below freezing. Circulating water is less likely to freeze, as movement prevents ice from forming. If you have a variable-speed pump, run it on low to save energy while keeping the water moving.

2.   Lower the Water Level Before Freezing Starts

Lower the water level slightly below the skimmer to protect your pool’s equipment and structure. This step reduces pressure from expanding ice. Just be careful not to drain it too much, as this can damage your pool liners or structure.

3.   Use a Pool Cover to Keep Debris Out and Heat In

A high-quality cover is a must for both inground and above ground pools. Pool covers help prevent cold air from reaching the water and reduce the chances of ice formation. They also keep leaves and debris out, making pool maintenance much easier when spring arrives.

4.   Add Winter Chemicals to Your Pool Water

Using specialized winter chemicals is a great way to keep your pool’s water balanced during the cold months. Algaecides and antifreeze products help prevent algae growth and protect your equipment from damage. Consult experts like RMD Pool Services for the right products for your pool.

5.   Protect Your Pool Equipment

Your pumps, filters, and heaters are vital to your pool’s health, so they need extra care in the winter. Disconnect and drain any pool equipment that isn’t being used. If you can, store it indoors to avoid damage. For larger systems, insulated covers can help keep the cold out.

6.   Monitor Pool Water Regularly

Even in the winter, your pool still needs regular checks. Check the water level, ice buildup, and equipment to catch potential issues early. A few minutes every week can save you from expensive repairs later.

7.   Install a Pool Heater or Freeze Guard

Investing in a pool heater or freeze guard is a smart choice if you live in extremely cold temperatures. Heaters keep the water warm enough to prevent freezing, while freeze guards automatically turn on the pump when temperatures drop to freezing levels.

8.   Winterize Your Pool Properly

If you’re not planning to use your pool in the winter, make sure it’s properly winterized. This includes balancing the water, draining equipment, and using a cover to protect the pool. Professionals like RMD Pool Services offer weekly pool maintenance, drain & cleaning services to keep your pool in top shape.

 

How to Keep Above Ground Pool from Freezing in Winter

Above-ground pools require extra care because they’re more exposed to cold temperatures. Here are a few quick tips to protect them:

  • Use a quality pool cover to trap heat and prevent debris buildup.
  • Lower the water level and use winterizing chemicals.
  • Insulate the pool walls with special covers or blankets.
  • Run the pump to circulate the water when temperatures drop.

Taking these precautions will keep your above ground pool from freezing and lessen the risk of winter damage.

 

FAQs

Do Inground Pools Freeze in the Winter?

Yes, inground pools can freeze in the winter if not appropriately maintained. While the surrounding ground provides some insulation, it’s insufficient to prevent freezing during prolonged cold snaps. That’s why running the pump, lowering the water level, and winterizing the pool are essential.

Can my pool freeze during the winter months?

Yes, pools can freeze in winter if not properly maintained. The cold can cause water to expand and damage your pool equipment and structure. Regular maintenance is key.

What can I do to prevent my pool from freezing?

Keep your pool pump running during cold weather to circulate the water and prevent freezing. Keeping the water moving is essential, especially when temperatures are below freezing.

Is a pool cover necessary for winter protection?

Absolutely! A high-quality pool cover helps trap heat, keeps debris out, and reduces the chances of ice forming. It’s an easy yet effective step to protect your pool.

Do I need to add winter chemicals to my pool?

Yes, winter chemicals such as algaecides and antifreeze protect your pool’s water and equipment. These specialized products maintain water balance and prevent algae growth during winter.
