A hot tub represents an investment, so you likely want to extend its life. A properly maintained hot tub should last 10 to 20 years. That lifespan represents a good return on your investment. The key is proper maintenance. The habits below can help you extend the life of your hot tub.
Keep Water’s Total Alkalinity
Part of your water care routine should be to keep your water’s total alkalinity, which is the ability of the water to buffer acids. Ideally, the alkalinity of the water should be between 125 to 150 parts per million. When your water has the proper total alkalinity level, you can keep the water’s pH stable.
You’ll need a spa test kit with strips to test the water periodically. If you test your water and find that the total alkalinity is below the target level, you’ll want to add an alkalinity increaser. You should add this chemical in small doses and test after each dose.
Maintain the pH Level of Your Water
Your hot tub water should have a pH level between 7.4 to 7.6. If the water falls below 7.4, the water is acidic. The water sanitizer might not work properly, which potentially exposes bathers to bacteria. Acidic water can also cause spa components to corrode. You’ll need to add pH increasers, which usually contain sodium carbonate.
If the hot tub water rises above 7.6, it’s basic. You have the same issue of the water sanitizer possibly not working well. However, you have an added danger to your hot tub — scaling. The high pH causes high calcium hardness, which results in a flaky, white buildup in your hot tub. For a tub with basic water, you need to add pH decreasers, which usually contain sodium bisulfate.
Clean the Hot Tub Water Filter
If you clean the hot tub water filter on a regular basis, you’ll have an easier time keeping your water at a good pH level. You should do a cursory cleaning once a week and a more thorough cleaning once a month.
For the weekly cleaning, you’ll start by removing the filter and examining it for damage. If any parts of the filter are damaged, you should replace rather than clean them. To clean between the pleats of the filter, use a filter cleaning wand with soft teeth to remove debris. Visually inspect between the pleats to ensure all the debris is gone before you replace the filter inside its cradle.
For the monthly cleaning, you’ll follow the above steps to remove debris. However, you should also soak the filter in a solution of water with a mild cleanser. Refer to your owner’s manual for the proper filter cleaner. After you’ve soaked the filter, you should rinse it to remove the cleaning solution before replacing it in its cradle.
Troubleshoot Your Water Pump
A hot tub’s water pump is a vital part of the whole system. Unfortunately, as with any motor, it can develop issues.
One common issue is the pump won’t prime. This issue usually happens when the filtration system has debris in it. The above cleaning should solve the problem. You can also turn the tub jets on and off to burp the system.
If your motor runs but fails to circulate the water, one of the impellers might be stuck. Listen as you run the motor. A grinding noise is a sign of a stuck impeller. Turn off the power and inspect the motor for the cause of the malfunction. You might be able to just clean the motor, but you may also need to replace the impeller.
A sign that you need to replace the whole motor is if it turns off and on randomly. The wiring may have become faulty. While replacement of the motor can cost a few hundred dollars, this expense is much lower than replacing the entire hot tub.
