9 Steps How To Winterize Your Hot Tub

Some will say absolutely do this if you are not going to use the tub.  Others will state that this is always a bad practice and can lead to unforeseen consequences.  So what are you to do?  First, take stock of your situation and ask yourself some questions.
  1. Why do I want to shut my tub down for the summer/winter?  There could be any number of answers from we simply are not going to use it due to excessive heat or cold, costs too much money to operate, or you are going to be gone for several months.
  2. What are the benefits and the drawbacks?  Some possible benefits are of course the savings of money on electricity and chemicals.  Some potential drawbacks are not doing it properly and potentially damaging the tub which might come with costly repairs that the warranty may or may not cover.

Winterizing your hot tub can be done and many people do it. That said, hot tubs are not designed to be without water, so it is extremely important to to winterize your spa properly, or find a professional to do it for you.

If you don’t hire professionals then you must read these proper procedures and follow them accordingly. There are a number of steps that need to be completed to successfully complete this process. I am going to list these steps below.

Here are the nine steps for winterizing your hot tub:

  1. Purge your hot tub. Since you are going to be draining it in the following steps, it is important to clean out the biofilm (bacteria, mold, fungus) from the plumbing. We recommend using Ahh-some Plumbing & Jet Cleaner or Aqua Clarity. Follow the regular purge instructions as you normally would. Once your purge is complete, now we move on to winterizing your tub.
  2. Disconnect your power (this should already be done by now as you should have turned your power off when you were draining the tub after the purge).
  3. Drain the Air Blower (if your tub is equipped with one)
  4. Loosen the unions on the heater and pump. You will need to remove the tub’s access panel to complete this. The purpose of this step is to drain as much of the water out as possible.
  5. Remove the drain plugs from the pump. Ensure you do this for every pump to again, drain out as much water as possible.
  6. Use a shop vac or a wet vac to suck any remaining water from the lines.
  7. Replace drain plugs once all the water is out.
  8. Add your hot tub antifreeze. You will want to pour one gallon into the top of each pup as well as the filter compartment. You will want to ensure you use an antifreeze that is designed for hot tubs or pools. Commonly many people use RV antifreeze.
  9. Put the cover on your tub.
  1. Make sure that you check all of your unions and valves to ensure they are tight. We want to make sure everything is sealed up to ensure proper water flow.
  2. Rinse or flush the antifreeze from your tub.
  3. Refill your tub, purge with Ahh-some, drain your tub, refill again, balance, and enjoy.
