Help! Hot Tub Leaks – Do This Immediately


A leaking hot tub is an immediate cause of concern. Start by diagnosing the source of the leak, and once determined, look for the best way to fix the problem. While there are cases when you can fix the hot tub leaks by yourself, there are also situations when it is best to call the pros.

Hot tubs have several openings, all of which can be sources of leaks. The valves and the jets can also be the culprits. Once you know the source of the leak, it will be easier to execute the necessary solution.

Thinking of how to fix a hot tub leak? Keep on reading and we’ll let you know the best things to do.

Detecting a Hot Tub Leak

The first thing that you have to do is perform a leak test. You will need a dye or food coloring. Fill the tub with water and add coloring. You don’t have to fill the entire tub. Once the coloring has been added, look at which part of the tub the colored water appears first, and this most likely the source of the leak.

If your hot tub comes with a side panel, remove it to easily determine the source of the leak. Many of these panels are attached using screws, so you might need to unscrew them first. Once it is open, drain the water in the tub and look for the source of the leak.

Find the Source of the Leak

After performing a quick test, it is now time that you determine the source of the hot tub leaks. This is one thing that requires patience. Below, we’ll talk about the leak sources and the best ways to fix them.

1. Pump

The hot tub or spa pump is one of the most common sources of leaks. The first thing you have to do is to turn off the source of power then inspect the pump. If you can see leaking water from the pump, this is most likely the culprit.

There are three parts of the pump that are often responsible for the leak. One of the most common is the seal shaft. If this is the problem, simply order a new seal. You don’t need a replacement for the entire pump.

Hot tub leaks can also be because of the union fitting. This is a three-component connector. A common solution is to replace the O-ring. Tightening the connectors is also a quick fix.

Lastly, the volute can also be the problem. This is the housing of the impeller. Chances are, you will need a replacement.

2. Heater

If the pump does not show any problem, it’s time that you move to the hot tub heater. The heater is also where you can find pressure switches and other parts that can also be responsible for the hot tub leaks.

If you are lucky, the leak can be from a specific portion or part of the heater. Otherwise, if the main heater is the problem, you need to replace it as soon as possible.

Repairing the heater, however, can be tricky, especially if you are not into DIY tasks. If you are unaware of how to troubleshoot a hot tub heater, it is best to instantly get in touch with the experts.

Between the pump and the heater, you will find the union fittings. They can also be blamed for the hot tub leaks that you are experiencing. There is a chance that they have loosened. You can tighten the fit or replace the union fittings when needed. Remember, use only your hands to tighten the fittings and never use a wrench.

3. Valves


When it comes to how to fix a hot tub leak, you should also inspect the valves in the different parts of the tub. Regular inspection and cleaning of the valves are important for hot tub care. Otherwise, they can be prone to problems and can be the source of the leak.

In some hot tubs, some valves are attached to the pump. In other cases, they are bolted together in a gasket and with separate compartments. Whether you have Intex hot tubs or Coleman hot tubs, among other brands, will have an impact on the location of the valves.

If there is a valve with a leak, remove the damaged component, and replace it. The commonly problematic valves are the ones that you will find around the pump.

In the case of most valves, they have two valves that are connected by screws. Remove the screws and replace the valves as needed.

4. Jets

You should also inspect the connections and the jets if you are interested to learn how to fix a hot tub leak. A leaking jet is a common problem. If this happens, one of the best ways to troubleshoot hot tub jets is to replace the gasket.

Twist the jets on the hot tub and pull it out of the surface. Inspect it quickly to see any problem. If it is already broken, replace the damaged jets. When installing new jets, make sure to use silicone sealants to make them tight and prevent leaking in the future.

5. Hot Tub Shell

The hot tub shells are made of different materials. Fiberglass is the most common material. It is often combined with other materials as reinforcement. If this is the problem, you should fix it as soon as possible before it gets worse.

As a part of the hot tub and spa care and maintenance, use a plastic repair kit to seal the crack while it is small. The problem becomes more complicated to fix when it becomes bigger. To quickly fix cracks in a hot tub, you will also need an acrylic patch.

If you are using an inflatable hot tub, there are also repair kits that you can use to patch the crack or the hole immediately to prevent water from leaking.

6. Plumbing

The source of the leak may not be from the hot tub itself but the plumbing or the fixture. If there are leaky pipes, a bonding adhesive can offer the perfect solution. Use a brush applicator to apply the adhesive directly to the source of the leak. Wait for it to harden before you turn on the water supply.

In most cases, there may be urethane foam insulation around the plumbing. If you want to inspect the pipes to be sure if they are the source of the problem, you might need to remove the insulation first.

Know When to Call A Technician

If you are unaware of how to fix a hot tub leak or if you aren’t confident that you can do it on your own, the best thing to do is to get in touch with a technician. They have the tools and the skills necessary to fix hot tub leaks. Do not risk making the problem worse before you seek professional assistance.
