How to Drain, Clean & Refill Your Sundance Spa

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 water in great condition.

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 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 use Whirlpool Rinse:

  • Remove your filters.
  • Remove your head rests.
  • While the water is still hot, add 250ML (half a bottle) of Whirlpool Rinse.
  • Turn your 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 Spa.

All Sundance hot tubs are equipped with a drain to remove the water. Here are the instuctions for draining by series:

Additional Drain Options

In addition to the internal drains, there are other options available to you.

The Quick Drain, is up to 5 times faster than the standard drain valve, 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.

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 new, fresh water you are adding.

Cleaning Your Sundance Hot Tub

Now that your spa 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 filters a clean (or replace your Sundance Micro Clean Filters). Read here for more on Hot Tub Filter Maintenance.

Refilling Your Sundance Hot Tub

When adding new water to your spa, put your garden 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 to above the top jet, you can turn the power back on so it can begin heating up (Do not power up the hot tub until your garden hose has been removed).
