How to Drain, Clean & Refill Your Sundance Hot Tub
Draining, cleaning and refilling your Sundance hot tub 3 or 4 times a year will ensure you are soaking in clean, clear water and minimize the amount of time and effort spent on keeping your Sundance hot tub water in great shape.
Here are some tips for you to make the process as quick and easy as possible!
Before Draining Your Sundance Hot Tub
Before you begin draining your Sundance hot tub water, It is a good idea to use Whirlpool Rinse once a year to clean and degrease the internal plumbing and help prevent the build up of calcium which can have a negative effect on the performance of your hot tub. Here is how to get the best out of your Whirlpool Rinse:
- Remove your hot tub's filters.
- Remove your hot tub's head rests.
- While the water is still hot, add 250ML (half a bottle) of Whirlpool Rinse.
- Turn your hot tub's waterfall on.
- If your hot tub has diverter valves, turn them to the centre.
- If your hot tub has air controls, turn them to the off position.
- Run Jet pumps for 2 hours (make sure all jets are running and have not been manually turned off). You will need to turn the pumps back on every 20 minutes.
You are now ready to begin draining your Sundance Hot Tub.
Draining Your Sundance Hot Tub
Once you are ready to drain your Sundance hot tub, switch the power off at the GFCI breaker.
All Sundance hot tubs are equipped with a drain to remove the water.
680 Series hot tubs have gravity drain's built in to them. The drain is located at either the front of the side panel or behind the front panel.
To operate, remove the drain cover, attach your garden hose and pull softly to open or simply attach your hose to the interior drain line to allow the water to flow out.
780 Series hot tub drains are situated behind the front panel. Remove the Quick Release Door and the drain line will be in the top right corner. Remove the black drain cap and attach your garden hose to begin the draining process.
All 880 Series hot tubs come equipped with the built-in Quick Drain feature, which comes with a thicker hose for faster drainage.
Older model 880 spas have a Quick Release Door that gives you access to the Quick Drain.
Upgraded 2019 and all 2020 880 series models feature the SunSide Cabinet. To access the Quick Drain you need to remove the front panel completely (the panel under the digital control panel). This is the same process for all 980 Series hot tubs as well.
To operate the Quick Drain, simply attach the provided hose and turn the gate valve to begin draining your water.
In addition to these internal drains, there are other options available to you.
The Quick Drain, Available at all 6 locations of The Sundance Spa Store (Burlington, Hamilton, Mississauga, Oakville, St. Catharines & Vaughan) is up to 5 times faster than the gravity drain, removing 10-12 gallons of water per minute.
As well as saving you time, the Quick Drain also vacuums the floor of your Sundance hot tub as it drains, removing leaves, grit, sand and any other debris from the bottom of your hot tub.
Another option for draining your water is the use of a small submersible pump that can be purchased at most hardware stores.
These are particularly handy during the colder months, if you need to do a quick water change.
Keep in mind that submersible pumps do not vacuum the bottom of your hot tub as the Quick Drain's do.
There will always be a little water left in the foot well of your Sundance hot tub. This can either be removed with a Shop-Vac or simply left in place as it will have no impact on the fresh new water you are adding.
Cleaning Your Sundance Hot Tub
Now that your Sundance hot tub is empty, you may want to give it a quick clean.
While it is tempting to use your favorite cleaning products on your hot tub, all you actually need is water and a little bit of vinegar. Using harsh cleaning products will result in foamy water when you refill your hot tub.
A product such as The Tub Scrubber can be used to remove any residual waterline build up.
Draining your Sundance hot tub also gives you a good opportunity to give your hot tub filters a clean (or replace your Sundance Micro Clean Filters).
Using a strong setting on your hose nozzle (but not a pressure washer), Spray down your pleated hot tub filter to wash out any debris that has collected inside the filter.
Occasionally soaking your Sundance hot tub filters in a Cartridge Cleaner, or spraying on some AquaMagic will help break down any organic matter trapped in the filter pleats and provide the filters with a deep cleanse.
Sundance Spas Micro-Clean filters used on 780, 880 & 980 models should not be sprayed or washed like a standard pleated filter, as they are completely disposable and maintenance free!
Giving your Vinyl Sundance hot tub cover a clean, and treating it with a UV Protectant, such as Restore is also advisable while you are draining and cleaning the hot tub to keep the vinyl of the cover from drying out and shrinking.
Refilling Your Sundance Hot Tub
When adding new water to your Sundance hot tub, put your hose into the filter well so that it runs through the pipes as it fills up, this will help prevent air locks upon re-start.
Once your hot tub is filled, you can turn the power back on so it can begin heating up (Do not power up the hot tub until the hose has been removed).
Now your Sundance hot tub is full, it’s time to test and treat your water so that you can enjoy it as soon as it heats up to your desired temperature.
While the water is still cold, you should add 100ML of Prevent II to eliminate and prevent staining and scale formation.
Once the water is up to your set temperature, you should use a test strip to check your water is balanced correctly.
After making any adjustments to the Alkalinity or pH (in that order) that are needed, you should add 1 capful (30g) of Sun-Boom to the water.
Once this is done, you’re ready to get your hot tub party on!
