Preparing your Hot Tub for Winter - 10½ easy steps

If you are planning in going away over the winter period? Taking a break from hot tubbing in the winter? Whatever your reasons, if you are not going to be around to take care of your hot tub or don’t plan on using it during the winter period, then it’s best to learn how to winterize a hot tub properly and safely.

Our fully trained technicians can take the hassle away from you by doing it all for you or you can do it yourself by simply following these simple and easy steps.

Please note: Its essential that all water is removed from the hot tub when closing down the hot tub yourself as any residue water left in the pipes can freeze and cause cracking which can be very costly to fix.

Essential tools

½. Make yourself a cup of tea, coffee or a festive mulled wine

Make your favorite warm beverage and place it in a thermal flask as depending on your water pressure, this job can take anything between 2-4 hours. Please note: We don't recommend drinking alcohol whiles carry our this job, so maybe leave the mulled wine until the job is complete (bah humbug).

1. Turn the power off

Make sure there is absolutely no power getting to your hot tub. If your hot tub was installed by a Penguin hot tub technician, switch the tub off by turning the rotary isolation switch to the off position which should be located near the hot tub (distance of 2 meters away from the hot tub).

2. Drain the hot tub water

Using either a submersible water sump pump or the drain valve, begin draining your hot tub completely. If you use the drain valve, some hot tubs will allow you to attach a garden hose to it. We would recommend using a submersible water pump instead of the drainage valve because the submersible water pump works much faster.

3. Drain The Air Blower

Check to see if your hot tub has an air blower. If it does, then you should get the remaining water out of it. To do this, turn off the heater – this will prevent the heater from being damaged when you turn the hot tub electric back on (the heater element should never run without water).

4. Remove Your Filters

Take the cover off your tub and remove all the filters from inside your filter well. At this time, it’s a good idea to clean them with filter cartridge cleaner. You don’t want to store away dirty filters. We recommended doing a 24-hour chemical soak to clean the filters for the winter.

Make sure that the filter well has no water in it. You can use either a wet vacuum or a sponge to help get all the water out.

5. Unscrew Any Fittings to Allow Drainage

Open the cabinet to your hot tub and locate the pump or pumps. If there are unions that attached the PVC pipe to the pump(s), loosen them. Remove all the drain plugs from the pump(s) as well. This will allow water to drain from your pipes if condensation builds up inside.

Make sure to keep the drain plugs in a safe place that you’ll remember.

6. Blow Out The Pipes

Using the wet vacuum, turn the setting to blow, or whatever will force air out instead of suction. Take your shoes off and stand inside your hot tub and place the wet vacuum hose up to all your jets. Work your way around the entire hot tub until you’ve blown out every single jet. For good measure, repeat this process to ensure all pipes are clear of water.

7. Remove the Rest of the Water

Now that you’ve blown out the pipes, you are going to have some more water in the hot tub.

Make sure you get all the water out of the hot tub by using the wet vacuum on suction setting or use a sponge. You don’t want any leftover water in the tub. Make sure the hot tub is completely dry.

8. Clean the hot tub Shell and Cover

Now that you have an empty hot tub, we recommend you give it a good cleaning with some hot tub cleaner. If the cleaner you use requires you to rinse with water, just make sure you remove that water before completely closing the hot tub down. Also, clean the cover by using a hot tub cover cleaner on both the outside and inside.

9. Secure the Cover

It’s important that you secure the cover to your hot tub by using the straps. If your hot tub cover will lock to your tub, then I suggest doing so. You don’t want anyone or anything getting inside the hot tub. You also want to protect your hot tub cover from blowing away in severe winds.

10. You’re Done!

You have successfully prepared your hot tub for winter. You now deserve the glass of festive mulled wine to get into the spirit of things.
