To keep a hot tub running hygienically and efficiently it’s essential to change the water regularly. Hot tubs hold a relatively small volume of water that if left unattended can not only make the hot tub unsuitable for use but can also seriously damage the mechanisms and workings of the tub. The hot tub’s filter and the chemicals that are used to keep the water clean will remove most impurities that enter the water but it’s impossible to remove them all making changing the water regularly one of the most important jobs in hot tub maintenance.
Keep it Regular
Ideally the water in a hot tub should be changed every 60 to 90 days. This of course depends on the amount of use the hot tub has had. If the water in the hot tub looks dirty or smells unclean then of course this means that a change of water needs to happen sooner. The amount of days between changing the water should always be used as a guideline.
Testing for Peace of Mind
Testing the water is perhaps the most useful way of checking if the water needs changing, particularly if the hot tub looks clear and clean. Looks can of course be deceiving so a test gives an accurate answer. Keeping the chemicals in the tub’s water balanced will help keep the water at a hygienic level but a Total Dissolved Solids (TDS) check will tell you exactly when the water should be changed. A TDS test is a strip that is dipped into the water to give a reading of the substances that are found in the hot tub water. This clear and immediate reading will tell you exactly when hot tubs need to be drained and refilled.
Monitor Your Use
If you’ve had a hot tub party where the tub might have had more use than usual then many people will opt to change the water afterwards. This is very often a god idea as more people in the tub means more dirt in the water. Even when guests shower before getting into the hot tub dust and dirt can still be carried in on feet while sunscreen and body lotions can cause a slick or film on top of the water. A water test is usually unnecessary after a hot tub party, one glance at the water should tell you all you need to know.
Having a hot tub can be a real investment and by keeping the water clean and balanced your investment will last longer and provide years of enjoyment.
