Pool leaks can be the source of endless frustrations and repairs, but there are thankfully some quick and easy ways to detect a leak without needing to call in a professional. In this article, we’ll cover the basics of how to detect a pool leak, the signs of a pool leak, and what to do when you find one. So, let’s get started and quickly find that leak yourself.

1. Signs of a Leak

Before jumping right into leak detection, it’s important to familiarize yourself with some basic signs that suggest a pool leak. Whether it’s a crack in the liner, a noticeable difference in the water levels, or an unexpected dampness near the pool, there are several signs that you should be aware of in order to identify the potential source of the leak.

A. Change in Water Levels

One of the first signs of a potential pool leak is a negative change in the water level. Since pools tend to slosh around a bit under regular circumstances, losing or gaining a significant amount of water could be evidence of a pool leak. Make sure when checking the water level, to keep an eye on the surface skimmer, pool returns, and waterfalls. All of these components can be the source of your pool’s lost water.

B. Accumulation of Debris

An overly accumulation of debris like loose dirt and leaves in the pool circulation system is also a sign of a potential pool leak. If it seems like your filter isn’t keeping on top of the debris as quickly as it should, then it might be more than just an old, inefficient filter. Excessive dirt, leaves, and other organic materials all point to possible leak spots that are sucking up too much water from your pool.

C. Dampness Around the Area

If you’re noticing dampness or wet spots around the pool area, then it’s time to go hunting for a leak. This might sound like a difficult task, but don’t worry, there are a few helpful ways to go about it. Generally speaking, start by checking any water lines that connect to your pool, as well as your pool deck joints and plumbing lines. Once you’ve isolated the source of the wetness, you might have just found the source of your pool leak.

2. DIY Leak Detection

Once you’ve identified the signs of a leak and isolated a few potential sources, it’s time to crack open the toolbox and get to work! Here are a few DIY leak detection tips to help you quickly find the source of your pool leak and get back to poolside relaxation in no time.

A. Pressure Test

One of the most accurate ways to test for a pool leak is to have your pool professionally pressure tested with an air compressor. This works by connecting a pump to the air compressor and slowly increasing the pressure until the test line in the pool displays the pressure. If the pressure increases or stays the same, then the pool is probably fine and there’s likely no leak.

B. Dye Test

Another easy way to detect pool leaks on your own is to do a dye test. Using a few drops of pool-safe food dye, in a few strategic spots like the pool skimmer and main drain, we can tend to determine whether or not there’s a leak based on how quickly the dyed water reaches the spot of the suspected leak. If the water immediately streams out of the location, then it’s most likely a pool leak.

C. Visual Test

The simplest and easiest way to detect a pool leak is to perform a visual test. This involves going around the pool and looking for any signs of cracks in the liner or the surrounding walls or tile. Any exposed plumbing in the pool could also be a weak point for a leak, so make sure to check those too. If any of these point to a leak, then repair the area immediately.

3. Fixing the Leak

Once you’ve completed the detection process and found the source of the leak, it’s time to jump into action and fix it. Depending on the type of pool leak you’re dealing with, it could be a simple patch job, or more in-depth repairs that require the help of a qualified professional.

A. Patch Job

For typical pool leaks that are the result of minor surface damage or age-related wear and tear, a simple patch job should do the trick to stop the leak. Depending on the type of pool, you might need a particular type of patch kit to complete this process. The kit would come with instructions that will guide you through the patching process.

B. Pool Expert

If the leak is more significant and potentially the result of a plumbing issue, then you’ll want to bring in a qualified pool expert to evaluate the situation and provide the necessary repairs. A professional will be able to properly diagnose and repair the leak as quickly as possible, while ensuring the job is done to the highest standard.

C. Taking Care of the Problem

When all is said and done, taking care of a pool leak is all about properly identifying the source of the leak and then quickly taking the necessary steps to restore the pool to its original condition. If you find yourself in a pinch and need assistance, don’t hesitate to call a qualified pool technician who can properly diagnose and repair the leak, while ensuring your pool is running safe and efficiently.
