How to Fix a Leaking Hot Tub

To fix small leaks in your spa, try using a leak-sealing liquid before doing any major repairs. It’s a quick and easy solution that doesn’t require many tools.

Remove The Filters From Your Spa

Remove the filters from your spa to allow the sealing liquid to flow freely and locate leaks. Simply locate the filters inside the spa and twist or pop them out. This will help you find the source of the leak without any obstructions.

Pour The Leak-Sealing Liquid 

Next, pour the leak-sealing liquid into the place where the water usually gets sucked in. This might be a little opening or vent somewhere along the inside wall of your spa.

If you’re not sure where that is, check the manual or look online for a guide specific to your model.

Let The Spa Run For a whole Day

After you’ve added the liquid, it’s time to let the spa run for a whole day. This might seem like a long time, but it’s necessary for the liquid to work.

During this time, the liquid will move around inside the spa, finding the small leaks and sealing them up. 

Check It

Once the day is over, check the water level. If it has stopped dropping, you’ve successfully fixed the leaks.

If it’s still going down, try again or look out for other potential issues, such as insufficient foam insulation around the pipes. 

Finding The Leaks

Check around the pump or heater for leaks in your spa or jacuzzi by removing the side panels and using a flashlight to look for signs of water. If leaks are found, focus on that area for repairs.

Identifying the Culprit

Leaks in your spa often result from cracked parts or worn-out O-rings. O-rings create seals between different components of your spa’s machinery, but they can dry out or crack over time.

Other parts of the pump or heater may also develop small cracks due to age or wear. Identifying these issues is crucial for restoring your spa to optimal condition. 

Time for a Fix

Once you’ve found the problem, it’s time to roll up your sleeves and fix it. First, ensure everything is turned off to avoid any electrical hazards. 

Carefully remove the broken parts or old O-rings. Take these with you to a pool supply store so you can find exact replacements.

This step is crucial because using the wrong parts can lead to more leaks or damage.

Replacing and Testing

Once the new parts are installed, follow the instructions for your spa model to ensure proper fitting. Turn the power back on and check for any water leaks. If everything is dry, the leak is fixed and you can enjoy your spa again. 

When the Spa Light Causes Leaks

If you notice the water in your spa or jacuzzi getting lower, it could be due to a leak in the light fixture. Check for a cracked casing or damaged seal near the light to identify the source of the water escape.

Take Out The Bulb

Here’s what you’ll do: First, carefully take out the light bulb. Then, unscrew and remove the whole light fixture to take a closer look.

Replace It

If there’s a crack in the light, replace it. If the seal is the issue, just get a new one. Installing a new light or seal is simple and similar to replacing the old one, but make sure to use a new seal to prevent water leakage.

Tip: A tight seal is crucial for keeping water contained.
