How to Drain a Hot Tub Like a Pro

By Laura Varnon, Marketing Coordinator

The Spa and Sauna company recommends you drain and clean your hot tub every 4 months, unless you have a salt water system. Then you can drain every 6 months (for the Ace System) or only once a year for the FreshWater System. You can do your Drain and Clean yourself or you can have our one of our skilled Concierge Techs do it for you.

If you do want to do your Drain and Clean yourself, here’s what you need to do.

Locate where the drain is located on your hot tub.

Drains are located in different locations depending on the brand and model of the hot tub.

On all Caldera and Hot Spring models it is located on the base below the front panel (on the same side as the control board). Keep in mind that the higher-level models have extra amenities to make draining easier. Consider the Hot Spring Highlife NXT and Highlife which have one drain for equipment and one for the whole vessel. Or the Caldera Paradise and Utopia, which have a valve that slides out. You pull it out and hook it to a hose (which you have detached from your house) and then push it half way back in for draining. Similarly, the Sundance 880 has two options for draining, a drain on the exterior of the siding and inside the cabinet a quick drain, which requires less time.

Freeflow Spas have a drain at the base not far away from the outlet.

Draining your spa using the Side Drains can take up to 6 hours. Typically, when we drain your spa, we siphon the water out using a sump pump to save time. You can purchase a sump pump for yourself if you desire faster drain times.

If your model accommodates it, hook a hose up to the drain to allow the water to come out faster.

It is typically more difficult to insert a hose on Caldera Vacanza, Hot Spring Hot Spot, and Freeflow Models. If cleaning your spa at home yourself is an important consideration, we recommend you consider upgrading to a model that allows for more simple draining.

While you wait for your spa to drain, The Spa and Sauna Company recommends you use this time to clean your filter.

Filters should be sprayed down with a hose monthly or soaked in Filter Cleaner and then sprayed with a hose before inserting back in to your spa every 4 months. If you soak your filter and drain your spa at the same time, you don’t lose any valuable hot tub time!

Once the spa is mostly empty, use a shop vac or even a bucket to get any remaining water out of the seats and footwell.

Our pros always use a shop vac.

You’ll also want to open your equipment compartment and vacuum out any cobwebs, dust or dirt.

Although you won’t see this from outside your spa, it’s important to keep the inside of your spa clean too.

Once the spa is drained, it’s time to clean it.

We recommend a mitt, washcloth or rag, and using BioGuard Off The Wall to clean the shell of your hot tub. We also suggest wearing gloves as the solution can be hard on your skin. Off The wall will clean dirt, stains, grease and scale. You will want to apply it all over the tub. Let it sit for a few minutes and then scrub it off. Rinse well with water.

We also suggest cleaning your pillows with water only.

You can also use this time to use The Original Gel-Gloss Polish and Protector on the shell.

Finally, use 303 Protectant on the cover and panels.

Put the drain cap back on.

This is one of the easiest but also one of the most important steps!

Refill the hot tub by inserting a hose through the filter as if you were filling the spa for the first time.

Then it’s time to wait.

Once the water is above the jet level, you can turn the power back on and allow the spa to begin to heat.

Depending on how cold the water was, and what kind of hot tub you have, your hot tub should warm up about 2 – 6 degrees per hour.

You will want to wait until the water has reached 80 degrees before testing the water and adjusting the chemicals.

Then the spa can continue to heat to your ideal temperature.

A few final reminders:

If you happen to have hard water or well water, you will want to add Stain and Scale Control at this time.

If you have an ACE or FreshWater hot tub, you will want to put Vanishing Act in for 24 hours, and flip it after 12 hours.

And that’s it, your final step is to get in and enjoy your hot tub!
