Hot Tub Winterizing/Closing |
 |
If you do not plan to use your spa during freezing weather, you will have to winterize it. Failure to winterize your spa will cause irreversible damage (in freezing temperatures) to the pump and plumbing lines. |
Winterization of your hot tub is easy. Follow the steps in this checklist each time you drain the water from your spa in freezing temperatures to prevent serious damage from occurring to your hot tub:

_______ |
Close all therapy control valves and open all jets. |
| Step 2: |
_______ |
Turn the spa circuit breaker off. |
| Step 3: |
_______ |
Drain your spa. We recommend using a submersible pump. If you don't have a submersible pump, you can attach a garden hose to the hose spigot, located on the primary water pump within the spa interior. Be sure to run the drain line to an area that can handle the drainage. (see Figure 1) |

Replace the pump plug(s) after all the water has drained from them. |
