How to Fix a Pool Skimmer Leak: The Ultimate Guide for Corpus Christi & Port Aransas Pool Owners

A leaking pool skimmer is one of the most common and frustrating reasons your pool might be losing water. If you’ve noticed your water level dropping, higher water bills, or standing water near your pool, you could be dealing with a skimmer leak. This article explains everything you need to know about pool skimmer leaks—from detection to repair—and why Pool RX LLC is your best choice for pool leak detection in Corpus Christi and Port Aransas, TX. Read on to learn how to protect your pool, save money, and keep your swimming pool in top shape!

What Is a Pool Skimmer and Why Do Leaks Happen?

A pool skimmer is a vital component of your swimming pool’s filtration system. It pulls water from the surface, trapping debris before it reaches the pool pump. Most in-ground pools and above-ground pools have at least one skimmer, usually installed on the pool wall at the waterline.

Skimmer leaks often occur where the plastic skimmer meets the concrete wall or pool liner. Over time, shifting soil, weather changes, and improper installation can cause cracks or gaps, especially around the skimmer throat or skimmer gasket. Even a small crack can lead to significant water loss, making leak detection and timely pool repair essential.

Signs Your Pool Is Leaking: How to Spot a Skimmer Leak

How do you know if your pool is leaking? Some of the most common signs of a pool leak include:

• Unusually high water bills
• Standing water near the pool or skimmer area
• A drop in the pool water level, especially if it stabilizes just below the skimmer opening
• Unbalanced pool chemicals or cloudy water

If you notice any of these, check around the skimmer for visible cracks, wet spots, or water seeping from the pool wall. These are classic signs of a pool skimmer leak.

Why Are Skimmer Leaks So Common in Coastal Texas Pools?

Corpus Christi and Port Aransas are known for their unique climate and soil conditions, which can make pool skimmer leaks especially common. Many in-ground pools are built with plastic skimmers encased in concrete. Over time, ground movement and temperature changes can cause the “cold joint” between the skimmer and pool wall to separate, leading to leaks around the skimmer. This is especially true if the skimmer was not fully encased in concrete during pool construction.

Wide mouth skimmers and older skimmer boxes are particularly prone to developing leaks as gaskets age or screws loosen. Regular pool care and inspection can help catch these issues early.

How Do You Detect a Pool Skimmer Leak?

Detecting a skimmer leak starts with a visual inspection. Look for cracks where the skimmer meets the pool wall or liner. Check the skimmer throat, skimmer face, and the body of the skimmer for any signs of damage.

If you suspect a leak but can’t see it, you’ll need to use more advanced leak detection methods. At Pool RX LLC, our certified professionals use advanced techniques and equipment to pinpoint the exact location of the leak quickly and accurately.

What Tools Are Used for Pool Leak Detection?

Professional pool leak detection uses a combination of:

• Acoustic listening devices from Leaktronics to hear water escaping from cracks or joints
• Dye tests to visually confirm where water is being drawn out of the pool
• Pressure testing for plumbing lines connected to the skimmer
• Underwater microphones (hydrophones) for detecting leaks below the waterline

These tools help us find the source of the leak without unnecessary digging or damage to your pool.

How to Perform a Dye Test Around the Skimmer

A dye test is a simple way to confirm a skimmer leak:

1. Turn off your pool pump to stop water movement.
2. Fill a syringe or dropper with red food coloring or pool dye.
3. Hold the dye near cracks or suspected leak areas around the skimmer.
4. Watch closely—if the dye is drawn into a crack or seam, you’ve found the leak.

This method works best for leaks at or just below the waterline. If you’re unsure, Pool RX LLC can perform a thorough dye test as part of our pool leak detection services.

Fixing a Leaky Pool Skimmer: Step-by-Step

Once you find the source of the leak, here’s how to repair a leaky pool skimmer:

1. Clean the Area: Remove debris and old sealant from the crack or joint.
2. Apply Pool Putty: Mix underwater pool putty as directed, roll it into a rope, and press it firmly into the crack. Smooth the edges for a tight seal.
3. Check the Gasket: If the leak is at the skimmer face, inspect the skimmer gasket. A worn or misaligned gasket is a common cause of leaks. Replace or reposition as needed.
4. Tighten Screws: Make sure all screws on the skimmer faceplate are hand-tightened evenly to ensure a proper seal.
5. Monitor for Leaks: Refill the pool with water and check the skimmer area for any signs of continued leaking.

If the leak persists or the skimmer is badly damaged, you may need a new skimmer installed by a professional.

When Should You Replace the Skimmer Gasket?

The skimmer gasket creates a watertight seal between the skimmer and the pool wall or liner. If you notice water leaking from the side of the skimmer or bottom of the skimmer, the gasket may be worn, kinked, or improperly installed.

Butterfly gaskets and 2-piece gasket sets must be installed correctly, with no liner or wall foam under the gasket. If you see leaks around the skimmer after tightening screws, it’s time to replace the skimmer gasket.

Can You Repair a Pool Skimmer Leak Yourself?

Some minor skimmer leaks can be fixed with pool putty or a new gasket. However, if the leak is beneath the pool deck, at the bottom of the skimmer, or involves the plumbing, professional leak detection and repair is recommended. DIY repairs may only provide a temporary fix and can sometimes make the problem worse.
