How to Disinfect a Hot Tub?

Hot tubs are a great place to relax, socialize and soothe aching muscles and bones. But to allow all that to happen, it’s necessary to have clean, disinfected water. Because of the small volume of water and the high temperatures, hot tubs can quickly become overrun by algae, mold, bacteria and viruses. To keep a safe and healthy bathing environment it’s important to know how to disinfect a hot tub and perform regular maintenance procedures. In this post, we’ll go over the various steps required to keep the hot tub a safe place for relaxing, socializing and soothing sore bodies.

Water Chemistry

If you can keep your water chemistry properly balanced you can be pretty sure that your hot tub will be safe to bathe in. To ensure your water chemistry remains balanced you need to test it on a regular basis. This can be done with simple paper test strips, reagent kits or taking a water sample to your hot tub dealership for testing. The results of these tests, which range from pH levels to cyanuric acid levels and almost everything in between, will inform you which chemicals need to be added to the water to bring it back into balance. Hot tub water should be tested weekly at a very minimum and more often if there’s a lot of rain or the hot tub is getting a lot of use.

Water Filters

Water filters play an important role in removing debris, body oils, hair and other particulates from the water. Keeping the water filters clean will reduce pressure on the water pump and heater and prevent the water from becoming cloudy. The filters should be rinsed with fresh water and inspected for damage every week to every month depending on use. Water filters require a deep cleaning three to four times a year. This is done by soaking them in a cleaning solution overnight. Water filters should be replaced on an annual basis or when they show obvious signs of wear.

Draining and Deep Cleaning

Hot tubs need to be drained and cleaned every three to four months. This allows you to start with a fresh batch of water and remove any accumulated gunk inside the hot tub. Before draining the hot tub, a pipe cleaning solution should be added to the water and allowed to circulate to disinfect the inner workings of the hot tub. Once the tub is ready to be drained it should be disconnected from the power source to prevent the water pump from operating while the tub is empty.

It’s important to monitor the draining of the hot tub because several thousand litres of water can cause significant flooding. Make sure the water is directed away from any houses or other structures. Ideally, you’d be able to drain it directly into a storm drain.

When the tub is empty, the inner shell should be cleaned with a soft cloth and hot tub cleaning solution. Be careful not to use abrasive cleaners as they could easily damage the shell. The hot tub cover should also be thoroughly cleaned as it can harbour mold, mildew and other organisms.

Refilling and Rebalancing

Once the hot tub has been cleaned, it can be filled up again with fresh water. You’ll need to test the water again and add any chemicals to get all the levels back into their appropriate ranges. The heater can be turned back on, and the water allowed to circulate long enough to ensure thorough mixing of the added chemicals.
