6 Common Reasons That Causes Crack in a Hot Tub

1. Poor Quality of Water

If the water in your hot tub is of poor quality, it can cause the tub to crack. The chemicals in the water can eat away at the tub’s surface, causing it to become weak and eventually crack. It may also happen that the water contains high levels of minerals, which can cause cracking. If your Hot tub is outdoors and exposed to the elements, it can also crack due to freezing temperatures.

2. Improper Installation

If your hot tub is not installed properly, it can stress the tub, leading to cracking. Ensure your hot tub is installed flat to avoid this issue. If the tub is not installed level, it can also cause cracking. Ensure the hot tub is level before using it to avoid further damage. If the tub is already installed and you notice that it is not level, you can try to level it yourself or hire a professional to do it for you.

3. Waterlogged

If the hot tub is constantly filled with water, it will eventually become waterlogged. This extra weight can stress the tub and cause cracking. To prevent this, ensure you only fill the tub up part way and empty it regularly. If the water level does become too high, you can use a siphon to remove the excess.

4. Chemical Imbalance

If the water in your hot tub is not properly balanced, it can cause the surface to become brittle and crack. Test the water regularly and add chemicals as needed to maintain a pH level between 7.2 and 7.6. You may also need to add additional chlorine or bromine levels to keep the water clean and free of bacteria. Ensure the pH balance is not too high or too low, which can cause serious skin irritation.

5. Extreme Temperatures

Hot tubs are designed to withstand high temperatures, but extreme fluctuations can still cause the surface to crack. You should avoid using your hot tub during extremely cold weather, as this can stress the unit and cause cracking. If you must use your hot tub during cold weather, keep the temperature consistent to avoid any extreme fluctuations.

6. Improper Maintenance

If you don’t maintain your hot tub properly, it can lead to several problems that can eventually cause the surface to crack. Be sure to clean your hot tub regularly and test the pH levels of the water to ensure that they are balanced. You should also regularly inspect your hot tub for any signs of wear and tear and make repairs as necessary to prevent further damage. Proper maintenance is key if you want to avoid having to fix a crack in your hot tub.

Step by Step Guide: How to Fix a Crack in a Hot Tub

Step 1: Prepare the Area

Use a tape measure to determine the length and width of the crack. Then, use a screwdriver to remove any loose debris from the crack. Be sure to clean out the area thoroughly so that the repair will be as effective as possible. Make sure the area is dry before proceeding to the next step.

Step 3: Clean the Area

Once the tub is drained, use a soft cloth to clean the area around the crack. This will help remove any dirt or debris that could prevent the repair kit from working properly.

Step 4: Apply the Epoxy

Mix the epoxy according to the instructions on the package. Once it is mixed, use a putty knife to apply it to the crack. Be sure to fill in the crack completely so it is sealed off from the rest of the tub. Make sure there is no air bubble in the epoxy. If you want to, you can add a little extra epoxy around the area just to be sure. Let the epoxy dry for at least 24 hours before using the tub again.

Step 5: Let the Epoxy Dry

Let the epoxy dry for at least 24 hours before using the hot tub. This will give the epoxy time to set and bond properly. Once it is dry, you can turn on the power to the hot tub and enjoy it as usual. If you find that your hot tub is still leaking, you may need to reapply the epoxy or try another type of repair. Make sure there is no water in the tub before you start this repair.

Step 6: Clean the Tub Again

Once the epoxy has dried, you should clean the tub again. This will help remove any dirt or debris that may have gotten into the tub during the repair process. Be sure to dry the tub completely before using it again. If the crack is still visible after the repair, you may want to consider replacing the tub.

Step 7: Add Water to the Tub

After cleaning the tub, you can add water to it. Be sure to fill the tub slowly so the epoxy has time to set. Once the tub is full, you can turn on the power and enjoy your hot tub as usual.
