Read on to learn why a skimmer leak can’t wait, how to spot the signs, and why professional help is your best bet for a trouble-free pool.

What Is a Pool Skimmer and Why Does It Leak?

A pool skimmer is a crucial part of your swimming pool’s filtration system. Located on the side of the pool, the skimmer draws in surface water, trapping leaves and debris in the skimmer basket before the water reaches your pool pump. Over time, the skimmer or the area around the skimmer can develop leaks due to shifting ground, aging gaskets, or cracks in the skimmer body or where it meets the pool wall.

Skimmer leaks are especially common in in-ground pools, where the connection between the plastic skimmer and the concrete pool wall is prone to separation and cracking. This can lead to water loss, increased water bills, and even damage to your pool’s structure if not addressed quickly.

How Do I Know If My Pool Skimmer Is Leaking?

Wondering if your pool is losing water faster than normal? Here are some telltale signs of a skimmer leak:

• You need to fill the pool with water more than once a week.
• You notice wet spots or standing water near the pool skimmer area.
• Your water bills are unexpectedly high.
• The water level drops to the bottom of the skimmer and then stops.

If you suspect a leak, it’s important to act quickly. Catching a pool skimmer leak early can save you from bigger, more expensive repairs down the line.

What Are the Most Common Causes of Skimmer Leaks?

Several factors can cause a pool skimmer leak:

• Cracks where the skimmer meets the pool wall: This is the most common spot for leaks, especially in in-ground pools with concrete walls.
• Worn or damaged skimmer gasket: The gasket seals the skimmer face plate to the pool wall or vinyl liner. When it fails, water can seep out.
• Cracks in the skimmer body: Over time, the plastic can develop splits or holes.
• Loose or damaged face plate: If the screws or plate are loose, water can escape around the skimmer face.

Charleston’s climate, with its shifting ground and heavy rains, can make these issues more likely for local pool owners.

Why Are Skimmer Gaskets So Important?

The skimmer gasket is a thin rubber or foam seal that sits between the skimmer face plate and the pool wall or vinyl liner. Its job is to prevent water from leaking out at the skimmer opening. Over time, exposure to chemicals, sun, and shifting ground causes the gasket to degrade. When the skimmer gasket fails, water can seep out from the side of the skimmer, leading to a leaky pool skimmer and water loss.

Replacing the skimmer gasket is often the first step in repairing a pool skimmer leak, but if the pool is still leaking, there may be additional cracks or issues in the skimmer body or pool wall.

How Do You Detect a Pool Skimmer Leak?

Detecting a skimmer leak starts with a visual inspection:

• Look for cracks or gaps around the skimmer face, especially where the skimmer meets the pool wall.
• Check for dampness or wet spots near the pool skimmer.
• Use the “bucket test” to compare water loss in the pool to evaporation: Place a bucket filled with pool water on a pool step and mark the water level inside and outside the bucket. If the pool’s water drops more than the bucket’s after 24 hours, you likely have a leak.

For more precise leak detection, a dye test is often used.

What Is the Dye Test for Skimmer Leaks?

The dye test is a simple and effective way to pinpoint the location of a skimmer leak:

1. Turn off the pool pump so the water is still.
2. Fill a syringe or dropper with pool-safe dye.
3. Slowly release the dye near the suspected crack or gasket area around the skimmer.
4. Watch closely—if the dye is drawn into a crack or gap, you’ve found the leak.

This test is especially useful for finding small leaks at the skimmer face, skimmer gasket, or around the skimmer box.

Can I Fix a Skimmer Leak Myself or Should I Call a Pro?

Some minor skimmer leaks can be fixed by homeowners using pool putty or sealant. If you find a small crack, clean the area, apply pool putty, and let it cure according to the instructions. However, if the pool is still leaking, the problem may be more serious and require professional attention.

For complex leaks—especially those involving the skimmer line, underground plumbing, or a failing skimmer gasket—it’s best to call a professional pool leak detection company. DIY fixes may only be temporary if the root cause isn’t addressed.

What’s Involved in Professional Leak Detection?

Professional leak detection goes beyond a simple visual check. At The Poolcare Pros LLC, we use a combination of:

• Visual inspection of the skimmer, skimmer face plate, and pool wall.
• Dye testing to pinpoint small cracks or leaks.
• Pressure testing to check the skimmer line and suction line for leaks.
• Acoustic leak detection using specialized listening devices to find hidden leaks in plumbing or underground areas.

This thorough approach ensures every leak is found and fixed, not just patched over.

How Can I Prevent Future Skimmer Leaks?

Prevention is key to a trouble-free pool. Here’s how to avoid future skimmer leaks:

• Regularly inspect the skimmer face, gasket, and skimmer box for cracks or wear.
• Replace the skimmer gasket every few years, or at the first sign of deterioration.
• Keep the water level at least an inch above the skimmer box to avoid stress on the gasket and skimmer body.
• Schedule annual pool inspections with a professional, especially before and after Charleston’s stormy seasons.
