What Is a Pool Skimmer Leak and Why Should You Care?
A pool skimmer leak happens when water escapes from the area around the skimmer—where it meets the pool wall, through the skimmer gasket, or from cracks in the skimmer box or plumbing. Even a small leak can lead to big problems, including:
High water bills
Pool equipment damage
Erosion around the pool
Pool wall or deck damage
Ignoring a swimming pool leak can turn a minor repair into a major expense. In Miami’s hot climate, water loss adds up quickly, making fast leak detection and repair essential.
How Do You Know If Your Pool Skimmer Is Leaking?
Wondering if your pool’s skimmer is the culprit? Look for these signs:
The water level drops to the bottom or just below the skimmer opening and then stops.
You see damp spots or erosion around the skimmer area outside of the pool.
You notice bubbles in the pool pump, which can mean air is entering through a leaky skimmer.
Your water bills are higher than usual.
A quick way to check: mark the water level on the side of the pool and monitor it for a few days. If the water consistently drops to the skimmer area, you likely have a skimmer leak.
What Are the Most Common Causes of Skimmer Leaks?
Several issues can cause a pool skimmer leak:
Worn or misaligned skimmer gasket: The gasket seals the skimmer faceplate to the pool wall. If it’s old, cracked, or not installed properly, water can leak through.
Cracks in the skimmer box: Over time, the plastic or fiberglass skimmer can develop cracks, especially where it meets the concrete pool wall.
Loose skimmer faceplate screws: If the screws aren’t tight, the seal around the skimmer will fail.
Separation between skimmer and pool wall: In gunite or vinyl pools, shifting or settling can cause the skimmer to separate from the pool wall, creating a leak path.
How Does a Skimmer Gasket Cause Leaks?
The skimmer gasket is a critical part of the seal between the skimmer and the pool wall. Here’s how it can cause trouble:
Improper installation: If the gasket is kinked, twisted, or not seated properly, water will leak around the skimmer.
Age and wear: Over time, gaskets dry out, crack, or shrink, breaking the seal.
Missing screws: Not having all screws tight and in place can let the gasket shift or leave gaps.
For above-ground and vinyl pools, there are usually two gaskets—one inside and one outside the pool wall. Both must be in good shape and correctly installed to prevent leaks.
Can Cracks in the Skimmer or Pool Wall Cause Leaks?
Absolutely. Cracks are a major source of pool skimmer leaks:
Plastic skimmer cracks: The body of the skimmer can develop splits, especially at the bottom or where the skimmer meets the concrete pool wall.
Gunite or concrete cracks: The area where the skimmer meets the concrete pool wall is a common problem area. Settlement or shifting can cause the skimmer to separate, leading to leaks.
Vinyl liner tears: In vinyl pools, tears around the skimmer faceplate can allow water to escape.
A careful inspection with a flashlight can help spot these cracks. If you see any, they’ll need to be sealed or repaired to stop the leak.
Visual inspection: Checking the skimmer area for visible cracks, worn gaskets, or loose screws.
Dye test: Adding a small amount of colored dye (like red food coloring) near suspected leak points. If the dye is drawn into a crack or gap, that’s the source of the leak.
Pressure testing: For plumbing leaks, pros may use special equipment to test the skimmer line for pressure loss.
Listening devices: At The Pool Guys, we use Leaktronics’ industry-leading leak detection equipment, which can pinpoint even the smallest leaks with non-invasive audio technology.
What Is a Dye Test and How Does It Help Find Leaks?
A dye test is a simple but powerful tool for finding leaks around the skimmer:
Fill an eye dropper with red food coloring or pool dye.
With the pool pump off and water still, squeeze a little dye near the suspected crack or gasket.
If there’s a leak, the dye will be drawn into the crack or gap, showing you exactly where the water is escaping.
This method is especially useful for finding small leaks that aren’t visible to the naked eye.
How Do You Repair a Leaky Pool Skimmer?
Fixing a pool skimmer leak depends on the cause:
Gasket replacement: If the gasket is worn or misaligned, drain the water below the skimmer, remove the faceplate, and replace the gasket. Make sure all screws are tight and the gasket is seated flat.
Sealant or pool putty: For minor cracks, apply pool putty or a waterproof sealant to the crack or gap.
Skimmer box replacement: If the skimmer body is badly cracked, it may need to be replaced.
Professional repair: For leaks where the skimmer meets the concrete pool wall or for plumbing issues, it’s best to call in the pros.
After repairs, refill the pool and monitor the skimmer area for leaks. If it’s still leaking, repeat the process or contact a professional.
