If you need to shutter your winter home it’s important to drain the spa completely and take a few added measures to winterize the spa in areas where the temperatures fall below 32 degrees. We provide a step-by-step guide for winterizing in the owner’s manual provided with every spa and also available online. While the process is straight-forward, it’s really important to take the time to ensure that all water is out of the pipes and spa to prevent any potential freeze damage.
If you plan to use your hot tub during the winter months, be sure to drain and refill your hot tub when temperatures are above freezing for long enough to drain your spa, refill it and allow the heater to bring the water back up to temperature. Much of that planning depends on where you live. If you can drain and refill your hot tub as late as mid-December, the water will last through winter until mid-March.
Also keep in mind that water evaporates quickly during a dry, cold winter. Be sure to check the water level to make sure it doesn’t fall below the skimmer level. If the water stops circulating, it won’t be heated.
