Winter is here! Some may be wondering how to protect your pool and spa from winter weather and freeze damage. While your spa or hot tub may be open all season, protection is still essential to keep it running efficiently. We have put together some helpful tips on how to protect your pool and spa from freeze damage this winter.

How to Protect Your Pool and Spa from Freeze Damage this Winter

Pool closing is a process that protects the equipment, the pool structure itself and the water chemistry. Properly closing your pool will make the opening of the pool the following summer much easier. In addition, it will help eliminate the growth of algae this winter.

Closing Your Pool During the Winter

Our Pool Design Process

  1. Balance pool water chemicals. Also, add shock treatment.
  2. Lower the water level in the pool needs so that it is below the skimmer.
  3. Make sure the pipes and pool equipment is clear of water. If water is left there and it freezes and expands, it will crack and damage the pipes and equipment.
  4. Add swimming pool antifreeze to the lines to prevent them from freezing.
  5. Secure the pool winter cover. Check the cover occasionally to ensure it is still secure and to remove any standing water. Resist the urge to remove chunks of ice because you could tear the cover.

Protecting Your Spa or Hot Tub

Hot Tubs & Swim Spas

Use Free Protection

Modern spa and hot tub packs typically have a freeze protection mode. This will turn on the circulation pump when temperatures get close to freezing.

Freeze protection works with an air temperature sensor that communicates with a controller. The controller is wired into the pump power circuit.

Run the Pump

As long as water is moving through all of the pipes, the water won’t freeze. Open up all of your jets, if your spa has the ability to isolate banks of jets. You can use a low speed, as long as all pipes are in use.

As long as the water is moving through all of the pipes and equipment when temperatures are below 32 degrees, the water doesn’t need to be hot. The heat from the spa pump, under a closed skirt, is also helpful to heat up the equipment. However, make sure to use a spa cover to avoid ice forming on the spa surface.

Additional Tips to Prevent Freeze Damage

  1. Add heat to your spa, as a hot spa can give 24 hours of protection.
  2. Keep a tight fitting spa cover in place and secure.
  3. Spa insulation can also prevent freeze damage. The more spa insulation, the more protection you have.
  4. Hang a 100 watt shop light, under the skirt next to the spa pack.
