Signs Your Pool May Have a Leak (And Why You Shouldn’t Ignore It)

Pool leaks are one of the most common — and most misunderstood — issues homeowners face. In Central Texas, soil movement and temperature fluctuations can increase stress on pool structures and plumbing systems.

While some water loss is normal due to evaporation, excessive loss may signal a leak that needs professional attention.

Here’s how to recognize the difference.

Normal Evaporation vs. Potential Leak

In hot weather, pools typically lose ¼ inch of water per day to evaporation. However, if you’re adding water more than once per week, you may have a problem.

A simple bucket test can help determine if the loss exceeds normal evaporation rates.

Common Signs of a Pool Leak

1. Constantly Low Water Levels

If your pool consistently drops below the skimmer line despite minimal splash-out, it’s time to investigate further.

2. Cracks in the Pool Shell or Deck

Small surface cracks are common, but widening cracks or separation between coping and decking may indicate structural shifting.

3. Wet or Soggy Spots in the Yard

Unexplained damp areas near your pool can signal underground plumbing leaks.

4. Air in the Pump System

If your pump basket shows air bubbles or struggles to maintain prime, suction-side plumbing leaks may be present.

5. Rising Water Bills

A sudden increase in water usage often points to undetected leaks.

Why Leaks Are Serious in Central Texas

Expansive clay soil reacts to moisture. When water leaks underground, soil can swell and shift, placing stress on your pool structure.

Over time, this can lead to:

  • Structural cracking
  • Deck lifting
  • Plumbing damage
  • Increased repair costs

Early detection prevents larger structural problems.

What Causes Pool Leaks?

Leaks may occur due to:

  • Aging plaster
  • Plumbing line failures
  • Seal deterioration
  • Structural movement
  • Poor previous repairs

Professional leak detection uses specialized equipment to pinpoint the exact source without unnecessary demolition.

Don’t Wait on Leak Detection

Small leaks rarely fix themselves. Addressing them early protects your pool’s structure and surrounding property.

If you suspect abnormal water loss, professional leak detection provides clarity and prevents escalating damage.

Need Professional Help With Your Pool?

Reading tips is helpful — but sometimes you need hands-on expertise.

Whether you’re dealing with a leak, planning a renovation, building a new custom pool, or just want reliable weekly service, professional support makes all the difference.
