Preparing Your Hot Tub for Winter

on December 2, 2014 in Care & Maintenance

Soaking in your hot tub during a snowy winter evening is a beautiful and relaxing experience. You keep warm in the heated hot tub water while ice-cold snow surrounds you, steam rising up. It’s a picturesque moment.

Even if it doesn’t snow where you live during the winter, a hot tub helps you to keep toasty on the chilly evenings. We suggest you use your hot tub in every season, including winter.

We have put together some steps you should take to prepare your spa for winter, whether you’re planning to use it or not. If you’re not planning to use your hot tub regularly during the freezing cold winter or are going out of town, you’ll have to follow simple steps to winterize and close your spa to avoid freezing damage.

Replace Your Hot Tub Cover if You Need To

You always want to make sure your hot tub is well covered up, but it’s especially important to do during the winter. A good quality hot tub cover will keep your water warm and keep snow and rain outside. If your cover is sagging or bowed, you’ll want to replace it before winter, even if you’re not planning to use your hot tub. Puddles of rain or snow can form on bowed or sagging hot tub covers, causing them to sag even more and possibly even crack.

Make sure to clean and condition your hot tub cover regularly during winter, and always push water off of your cover after rainfall, snowfall or your time in the hot tub.

Drain, Inspect and Clean Your Hot Tub

Whether you plan to close your hot tub for the winter months or not, you’ll want to drain and clean it. You’ll be creating a safe and clean environment for all of the relaxation you’ll be having throughout the winter months, or for when you begin using your hot tub again. It’s better to clean your hot tub before the cold winter months than during.

To drain your hot tub, follow these simple steps:

  1. Close all therapy control valves and open all jets.

  2. Then, turn the spa breaker off.

  3. Now it’s time to drain the water out. We recommend doing this with a submersible pump. If you don’t have one of those, you can attach a garden hose to the hose spigot, which is on the primary water pump within the spa interior.

  4. Finally, open the spigot to allow your spa to drain.

When your spa is drained of all water, inspect the jets, pumps, valves, pipes and filters for any damage and built up dirt. You should also check your shell and the mechanics behind the panels of your tub for any cracks or leaks. If you do find any damaged parts, you can replace them or contact us. Our representatives are available for service and repairs year-round.

After you have inspected your hot tub for any problems, dry it off and clean the shell’s surface with an all-purpose cleaner. Then, apply ThermoGloss to your shell to polish and protect its acrylic surface. Next, clean your hot tub filters to ensure that they work effectively during the winter. Finally, if you plan to use your hot tub during winter, detach your hose, close the spigot tightly and refill your hot tub with fresh, clean water. When you’re spa is filled up to normal operating levels, turn your spa’s circuit breaker back on.
