Fixing Spa Leaks
Leaks in pools and spas can be particularly frustrating for homeowners due to the complex nature of determining the cause and location of the leak. And while some leaks require professional assistance to repair, there are others that can be fixed using DIY methods.
Here are some of the most common areas you can encounter leaks in your spa and how to mend them:
Spa pumps are often the culprit when it comes to leaks in your spa. Prior to checking your pump, be sure to turn off the power. Then, look underneath your pump for leaking water, as this is the easiest way to determine whether your pump has a leak. If so, the problem is likely related to the pump seal. However, in some cases, you may need to replace the pump entirely.
In most cases, due to the robustness of the shell’s fibreglass design, leaks are rarely to do with the shell and more likely caused by faulty components that are attached to the shell, such as the jets. However, if you do notice a crack in the shell, you can apply Plast-Aid (available in most pool and spa stores) to fix the issue.
Union fittings connect the plumbing to your spa components and can be a cause of leaks due to loosening gradually over time. To fix the issue, simply tighten any loose fittings by hand. We do not recommend using a wrench or similar tools to tighten fittings.
Your spa heater and all associated parts, such as the pressure switch can also be a source for spa leaks. Unfortunately, this is a more serious issue and will likely require new components to be ordered to replace the existing faulty parts.
Spa connections refer to elements such as your jets and pipes. This can be a particularly easy fix in some instances, where all that is required is resealing or tightening any compromised or loose connections. If you notice the leak coming from a jet, this can usually be attributed to a faulty gasket, which will need replacing. If the leak is coming from a pipe, you can often repair this using Plast-Aid, which we mentioned above.
Spas consist of a number of different valves that are prone to leaks over time. The type of valve that is causing the leak will determine what needs to be done to fix the issue. We recommend taking a photo of the valve you suspect is causing the leak and taking it to your local spa shop to ensure you’re taking the right steps to resolve the problem.
The easiest way to locate leaks in both pools and spas is to use the food colouring method. To do this, simply purchase a dark food colouring and apply a small amount to your spa water. Then, all you need to do is observe the movement of the coloured water, which will likely lead you to the problem area.
In any case, if you do not feel comfortable repairing leaks yourself, we highly recommend consulting your local pool and spa retailer or technician to ensure the issue is dealt with correctly to avoid more costly problems down the track.
