Types of Hot Tub Leaks

If you think your hot tub might be losing water, the first thing to do is look for any leaks. You can use a special kind of material called sealant to stop different types of leaks in your hot tub.

  1. Leaks around the edges: Sometimes, water can leak from the sides of the hot tub where it meets the ground. Sealant can be used to seal the space between the tub and the ground so that water doesn’t escape.
  2. Jet leaks: Hot tubs have jets that can leak water if the rubber seals around them are old or damaged. You can use sealant to cover these jets and prevent water from leaking out.
  3. Drain leaks: The drain at the bottom of the hot tub can also start leaking if its rubber seals are worn out. Sealant can be used to seal the drain and stop the water from leaking.
  4. Fitting leaks: Other parts of the hot tub, like the skimmer, filter, and heater, might start to leak over time. Sealant can be applied to these parts to stop the leaks.
  5. Cracks in the shell: If you see cracks or damage in the tub’s outer layer, you can use sealant to cover these cracks and prevent water from escaping.

Remember, sealant isn’t a forever solution. You might need to put more on later to keep it working well. It’s important to fix leaks as soon as you find them so your hot tub and the area around it don’t get damaged.

There are many kinds of sealants, but the main ones are water-based latex, acrylic, butyl, polysulfide, silicone, polyisobutylenes, and polyurethane sealants. Don’t worry too much about the list – what’s important is that there are lots of options to choose from. You can find special sealers just for hot tubs in stores today.

How to Find a Leak in a Hot Tub

Step 1: Look at the Outside:

To begin finding where the leak might be, start by checking the outside of your hot tub. See if there’s any water gathering around the tub or if the area around it feels damp. Pay extra attention to where different parts of the tub meet and where you can access its insides. Leaks often happen in these spots.

Step 2: Check the Stuff Inside:

Next, take a good look at the things inside your hot tub, like the pump, heater, and pipes. Check for any water drops, small pools, or wet marks around these parts. If something seems strange, like there’s more water than there should be, it might mean there’s a leak in the equipment that needs fixing.

Step 3: Look at the Jets and Pipes:

Take your time to closely check the jets and pipes in your hot tub. See if there are any cracks you can see, connections that seem loose, or rubber seals that look damaged. You might need a flashlight to help you look, because sometimes leaks are hard to spot inside the pipes. Also, run your hand along the pipes to see if they feel wet or damp.

Step 4: Try Leak Detection Products:

If you haven’t found where the leak is after trying the other steps, you can use special products made to find leaks. These products might be tablets you put in the water or solutions you add to the hot tub. They’ll move toward where the leak is, making it easier for you to figure out where the problem is happening.

Common Causes of Hot Tub Leaks

You should be aware of some of the more common causes of leaks in hot tubs. The following are some of these:

Wear and tear

Hot tubs are subjected to a lot of wear and tear over time, which can lead to leaks. Components such as the shell, jets, fittings, and plumbing can become worn or damaged, leading to leaks.

Incorrect installation

If the hot tub is not properly installed, it can be more prone to leaks. This can include issues with the foundation, plumbing, or electrical connections.

Poor water chemistry

Poor water chemistry can cause damage to the hot tub’s shell, plumbing, and other components, leading to leaks.

Age

As hot tubs age, they may become more prone to leaks due to wear and tear and other factors.

Freeze damage

In areas where temperatures drop below freezing in the winter, hot tubs may be at risk for freeze damage. If the water in the hot tub’s plumbing or components freezes, it can cause the material to crack or break, leading to leaks.

Impact damage

If the hot tub is subjected to impact, such as from falling objects or people jumping in, it can cause damage that leads to leaks.
