Pool Skimmers: The Most Common Pool Leak Location

Our Guide on How To Fix Leaking Pool Skimmers

Pool maintenance involves many tasks, from balancing chemicals to cleaning filters. Another common problem homeowners can face is a leak. Millennium Pools & Spas have often found that pool skimmers are a frequent source of these leaks. Spotting and fixing them quickly is key to protecting your investment and keeping your family swimming safely all summer. For homeowners in Virginia, Washington D.C., and Maryland, understanding this common issue is the first step toward a hassle-free pool season.

What Are Pool Skimmers?

Pool skimmers are essential components of your pool’s circulation system. You can find these rectangular openings on the side of your pool, near the water’s surface. Their main job is to pull water from the pool’s surface, along with floating debris like leaves, insects, and oils. This water then flows through a filtration system before returning to the pool. In-ground pool skimmers feature a basket to catch larger debris, preventing clogs in the plumbing. By keeping the water surface clean, skimmers help maintain water clarity and hygiene.

Why Are Pool Skimmers Prone to Leaks?

Pool skimmers are prone to leaks for several reasons. They are constantly exposed to the elements, including sun, rain, and fluctuating temperatures. This exposure can cause the plastic housing to degrade and crack over time. Ground movement and shifting soil can also put stress on the skimmer body and the plumbing connected to it. Furthermore, the connection point where the skimmer attaches to the pool’s concrete shell is a common failure point. Chemical imbalances can also accelerate the deterioration of skimmer components.

How Do I Know If My Pool Skimmer Is Leaking?

Several signs can indicate whether skimmers are leaking in your pool. The clearest sign is a noticeable drop in the pool’s water level, faster than what evaporation would cause. You may also see cracks in the concrete or tile around the skimmer. Wet or eroded soil directly outside the pool wall near the skimmer is another strong indicator of a leak. To confirm, you can perform a simple dye test. With the pump off, squeeze a few drops of pool dye near the skimmer’s opening. If the dye gets pulled into a crack, you’ve found your leak.

What Are the Most Common Causes of Skimmer Leaks?

Skimmer leaks can disrupt your pool’s efficiency and lead to water loss. Understanding potential causes helps address issues early. Below are the most frequent reasons why pool skimmers leak:

• Separation From the Pool Wall: Gaps between the skimmer and the concrete allow water to escape.
• Cracking in the Skimmer Body: Freezing and thawing during winter can cause cracks in the skimmer’s plastic.
• Aging Skimmer Materials: Over time, seals and plastic degrade, leading to leaks.
• Improper Installation: Poorly installed skimmers may fail prematurely under pressure.
• Ground Settlement: Shifting soil can put stress on the skimmer, causing cracks or leaks at connection points.

How to Diagnose or Repair a Skimmer Leak?

Figuring out how to fix leaking skimmers in your pool starts with a proper diagnosis. After confirming a leak with a dye test, the repair can begin. For minor cracks in the skimmer body, a two-part epoxy putty designed for underwater use can be effective. This putty can be applied directly to the crack to create a durable seal. For extensive damage, the entire skimmer may need to be replaced, a job best left to professionals.

How Can I Prevent Future Skimmer Leaks?

Protect your pool skimmer and avoid future leaks by staying proactive. Regular care not only extends the life of your skimmer but also helps avoid costly repairs. Here are key steps to keep your skimmer in great condition:

• Balanced Water Chemistry:Keep your pool’s water chemistry balanced to reduce wear on plastic components and avoid damage.
• Winterize Properly: Prepare your pool for winter to prevent freeze-thaw cycles that could cause damage to the skimmer.
• Regular Inspections:Check your skimmer and surrounding areas for cracks or signs of wear to catch issues early.
• Clean Skimmer Basket:Keep debris out to prevent clogs that can strain your system and cause leaks.
