Why should you drain your spa?

At first, it may seem overwhelming trying to figure out how to drain a swim spa and wondering whether it’s even necessary. Don’t worry, at mySpa Sydney we’re here to simplify the whole process. Firstly, it’s important to note that you should drain your spa to keep the water in it clean. If you don’t drain a swim spa it can become improperly balanced which means it’ll start calcifying. The temperature that spas operate at makes them a breeding ground for bacteria. Every time your swim spa is used, many organic and inorganic contaminants will make their way into the water. This can include body oil, body hair, skin cells, lotions and perfumes. Even if everyone has great hygiene, these contaminants will still make their way into the water of your swim spa. This can also impact the plumbing of your spa as some bacteria may survive and make it's way into the plumbing system. This is why you need to drain your spa as well as rinse and replace your filters. This will ensure you get the best experience when using your swim spa.

How often should a spa be drained?

It is recommended that your spa should be drained and refilled completely every 4 to 6 months. However, if there has been heavy usage of your spa then it should be drained more often accordingly. Some signs that your spa needs to be drained include if the water has become foamy, or feels slimy. If the water is starting to look discoloured, filmy or foamy then it’s time for the spa to be drained. Basically, if the water doesn’t look clean and clear like the last time you refilled it then it’s time to drain the spa.

Place the pump inside the spa.

Attach the garden hose to the drainage point. Run the other end of the hose downhill or on a level ground out to your drain.
