How to Spot Pool Leak Problems Before They Get Worse

Pool leaks are one of those issues that can quietly cause serious damage if not caught in time. What starts as a slight drop in water level can escalate into structural damage, higher utility bills, and even erosion around your pool’s foundation. At Beltway Pools, we’ve helped hundreds of homeowners in Virginia, Maryland, and Washington, DC identify leak problems early and take action before they become expensive headaches. In this article, we’ll walk you through the early warning signs of a pool leak, the risks of ignoring them, and what steps you can take to prevent long-term damage.

Subtle Signs That Your Pool Might Be Leaking

Not all pool leaks are obvious. In fact, many start so small that they go unnoticed for weeks—or even months. A common early warning sign is a water level that drops faster than expected. While evaporation is normal (especially during the hot summer months in the DMV area), a consistent loss of more than a quarter-inch per day may indicate a problem. You might also notice damp or soggy patches around your pool deck, which could suggest underground leaks. Other red flags include cracks in the pool shell, loose tiles, air bubbles in your return jets, or difficulty keeping your pool properly balanced with chemicals.

How to Confirm a Leak Before Calling a Pro

Before scheduling a professional inspection, there are a few simple DIY tests that can help confirm whether or not you have a leak. The most popular method is the bucket test. Fill a bucket with water and place it on a pool step so that the water level inside the bucket matches the level in the pool. After 24 hours, compare the levels. If the pool water has dropped more than the water in the bucket, it’s likely you have a leak. Another trick is to use food coloring near suspected cracks or around fittings. If the color gets drawn into a crack or crevice, that’s another sign water is escaping. While these tests won’t tell you exactly where the leak is, they’ll let you know it’s time to bring in an expert.

Why Prompt Leak Detection Matters

Delaying leak detection can be a costly mistake. Left unchecked, a minor leak can lead to soil erosion, structural instability, and damage to nearby landscaping or hardscaping. In some cases, leaks can even cause damage to the foundation of your pool, requiring major reconstruction or full-scale renovation. At Beltway Pools, we’ve seen firsthand how small leaks can spiral into major problems when homeowners wait too long.
