Pool Skimmer Leak Detection: Finding & Fixing Your Pool Leak

A pool leak can turn your backyard oasis into a source of stress-especially when the skimmer is the culprit. Skimmer leaks are among the most common pool problems in San Antonio, TX, due to our region’s unique climate and soil conditions. This guide explains how to detect, diagnose, and repair a pool skimmer leak, why it matters for your pool’s health, and how South Texas Pool Leak Detection uses cutting-edge LeakTronics equipment to keep your swimming pool watertight and worry-free.

Whether you’re a pool owner noticing a drop in water level or a local resident searching for expert pool leak detection, this article will help you understand the process, spot the signs, and know when to call in the pros.

What Causes a Pool Skimmer Leak?

A pool skimmer leak usually happens where the plastic skimmer meets the concrete pool wall. Over time, ground movement, shifting soil, or simple wear and tear can cause the skimmer to separate from the pool shell, leading to cracks and water loss. In San Antonio, the hot sun and shifting soils make this problem even more common. The gasket or sealant around the skimmer faceplate can also degrade, allowing water to escape.

Sometimes, the skimmer body itself develops a crack, especially in older pools or those with plastic skimmers. If left untreated, even a small crack can lead to a significant pool leak, causing you to lose water and potentially damage the pool structure.

How Do You Know if Your Pool Skimmer Is Leaking?

The most obvious sign of a skimmer leak is a pool losing water faster than normal evaporation would cause. If you notice your water level dropping, especially near the skimmer, it’s time to investigate. Other signs include wet spots around the pool, increased water bills, or air entering the pool pump.

A simple way to check is to let the water level drop naturally. If it stops just below the skimmer opening, that’s a strong indicator the leak is around the skimmer. You might also see cracks forming around the skimmer faceplate or notice debris in the skimmer basket that shouldn’t be there.

Why Are Skimmer Leaks So Common in San Antonio?

San Antonio’s climate is tough on pools. Extreme heat causes expansion and contraction in the pool shell, while shifting soil can move the skimmer out of alignment. This ground movement is a leading cause of cracks where the plastic skimmer meets the concrete pool wall. Over time, these cracks widen, and water begins to escape.

Additionally, chemical imbalances and aging plaster can deteriorate the sealant around the skimmer, making leaks more likely. That’s why regular inspections and timely repairs are crucial for pool owners in our area.

What Are the Signs of a Pool Leak?

Common signs of a pool leak include:

Water level dropping faster than usual
Wet spots or soggy ground near the pool skimmer or pool wall
Air bubbles in the pool pump or loss of prime
Cracks forming around the skimmer or pool shell
Needing to add water to your pool more often than normal

If you notice any of these signs, especially around the skimmer, a leak is likely present and should be addressed quickly to avoid costly repairs.

How Does Pool Leak Detection Work?

Professional pool leak detection involves a combination of visual inspection, pressure testing, and advanced listening equipment. At South Texas Pool Leak Detection, we use LeakTronics’ industry-leading technology, which allows us to pinpoint leaks with incredible accuracy-even those hidden in underground plumbing or behind pool walls.

The LeakTronics Pool Scope can detect the sound of water escaping through a crack or faulty seal. As the equipment gets closer to the source of the leak, the sound becomes louder, helping us zero in on the exact problem area. This non-invasive approach saves time, money, and avoids unnecessary digging or damage to your pool.

How Do You Perform a Dye Test for Skimmer Leaks?

A dye test is a simple way to detect leaks around the skimmer:

Turn off the pool pump so the water is still.
Fill a syringe or dropper with pool-safe dye.
Slowly release the dye near the suspected crack, gasket, or where the skimmer meets the pool wall.
Watch to see if the dye is drawn into a crack or gap-if so, that’s where the leak is.

This test can help you confirm the source of the leak before moving on to repairs.

Can You Repair a Leaky Pool Skimmer Yourself?

Minor skimmer leaks, such as small cracks or worn gaskets, can sometimes be repaired by a handy pool owner. Pool putty or specialized sealant can be used to fill small cracks or gaps around the skimmer faceplate. Replacing a gasket or tightening screws may also solve the problem.

However, if the crack is large, the skimmer body is damaged, or the leak is in the underground plumbing, it’s best to call a professional. Attempting major repairs without the right tools or experience can lead to bigger problems.

What Tools and Materials Are Needed for Skimmer Leak Repair?

To fix a pool skimmer leak, you may need:

Pool putty or waterproof epoxy for cracks
Replacement gasket for the skimmer faceplate
Screwdriver or wrench to tighten or replace screws
Pool-safe dye for testing
Sealant for sealing gaps where the skimmer meets the pool wall

These materials can handle minor repairs, but for more serious leaks, professional leak detection and repair services are recommended.

When Should You Call a Professional for Pool Leak Detection?

Call a professional if:

The water loss is significant or ongoing
You can’t locate the source of the leak
The crack is large or in the pool structure
The leak is in the pool plumbing or underground
DIY repairs have failed or made the problem worse
