Knowing how to winterize your hot tub is part of the basic hot tub maintenance. If you are not planning to use your hot tub during the winter, you must winterize it or it will cause severe damage to your plumbing lines and pump. Here’s how you go about doing the job.

Step 1 — Getting Started

Start the job by opening all the jets and then turning off the control valves and water supply.

Drain the water from the tub, using a garden hose or a submersible pump. Drain the water to a line that can handle such a large amount of drainage.

Then, disconnect the hot tub by unplugging the power cord, switch off the heater, and turn the power button off. The hot tub's circuit breaker should also be switched off.

Step 2 — Take out the Cabinet Panel and Drain Plugs

Take out the cabinet panel located in front of the hot tub’s equipment compartment. Open the spigot that is near the main pump and drain the water, leave the spigot open.

Use a wet vacuum (cylinder type) to clear the lines of any remaining water.

Remove the drain plugs from the water pumps and let the water drain out. After the water has drained, replace the plugs for the pumps.

Step 3 — Turn on the Blower

Replace the cabinet cover, and turn on the circuit breaker. Turn on the blowers to clear water form the air channels and pipes. Remove the fittings and clean it with the wet vacuum, this will remove all water from the fittings. Use a sponge to remove any remaining water.

Wipe the tubs interior as well as exterior with a cotton towel. After it is completely dried, place the cover on the tub and close it.

Step 4 — Securing the Tub

Because the tub will not be used for a while, it is better to cover it up properly so that it does not attract dirt or insects. Use a tarp to cover the tub and tie it down so that it remains in place.

In case your hot tub is in its warranty period, then before you embark on any hot tub maintenance activity check the terms and conditions. Sometimes the manufacturers provide service only if it has been winterized by a professional.

Step 5 — Finishing

Make sure you have properly closed the panel after you opened it; check that the circuit breaker and power supply is turned off. The water supply to the tub should also be shut off, so that no water gets into the plumbing. Once you are done with that, your hot tub has been winterized.

Once spring arrives, you will need to turn the circuit breaker and power supply back on. It's also important to clean your hot tub before you use it. Use bleach or ammonia for the first cleaning to be sure that you are properly disinfecting the tub.
