Swim spas are ideal for swimming enthusiasts in colder climates because it’s possible to run them all year round. Unlike full sized swimming pools that will begin to ice up once the temperatures drop below freezing , the smaller volume of water in a swim spa makes it possible to keep the water temperature high enough to prevent freezing in even the coldest of weather. But for those who don’t like the idea of being outside in a swimming suit in frigid temperatures, it’s possible to shut your swim spa down for the season. If you’re wondering how to winterize a swim spa safely, we’ve put together a generalized guide to help get you started. It should be noted that every model of swim spa is slightly different, so referring to your owner’s manual or speaking with your dealer for specific information will be necessary.
What You Need To Winterize A Swim Spa
It’s important to understand that if you aren’t going to use your swim spa over the winter, winterizing it properly is absolutely necessary. Ice can severely damage the plumbing and mechanical components and leave you with major repair bills. If you don’t feel confident in your abilities to do this job yourself, remember you can always hire a professional. But if you want to give it a shot, give your owner’s manual a thorough reading and have the phone number of your local swim spa dealer handy. You’ll need a wet and dry shop vac that provides both suction and blowing capabilities. A quantity of dry towels that you aren’t afraid to get dirty will also be of use.
Remove Water Filters
The first step is to remove your water filters. This is also a good time to give them a deep cleaning by soaking them in an approved cleaning solution. Once cleaned, allow them to dry and store them somewhere indoors over the winter.
Drain The Swim Spa
You’ll need to empty the swim spa to prevent it from freezing up. Depending on the type of system you have, remove the cap off the drain, hook up the pump or create a siphon using a length of hose to remove the water. Make sure the water is draining somewhere that can handle it. You don’t want to end up flooding your basement or creating a permanent pond in your backyard.
Run The Air Blower
Once the tank is empty, replace the cover and run the air blower for about a minute. This will get most of the excess water out of the air channels.
Drying Out The Swim Spa
You can now turn your swim spa off, trip the electrical breaker switch and hit the kill switch. Now you need to get any excess water out of the water pump, heater, filter housings and jet valves. Loosen up any couplers on the pump and heater and open the drains and/or bleed valves. Blow out any remaining water with the shop vac. Do the same with the jet valves by opening them up and blowing them out with the shop vac. Now’s a good time to give the shell a thorough cleaning to prepare it for winter. After cleaning the tank, remove any water that remains at the bottom with the shop vac and towels. Everything should now be completely dry.
Cover It Up For Winter
Replace the cover on the swim spa and make sure it’s properly locked down. If the cabinet has doors that lead to the mechanical components, make sure they’re secured. It’s best to place a tarp over top of the swim spa cover to protect it from the weather and prevent any moisture from getting inside.
