Evaporation or Leak? Why Austin Pools Lose Water

Homeowners across Austin ask the same question every spring and summer: why is my pool losing water? Is it normal evaporation or a leak? This guide breaks down how to tell the difference and when to call a professional.

Why This Matters in Central Texas

Central Texas weather puts unusual stress on pools. Long heat stretches, hard water, and quick temperature swings can accelerate water loss. If it's a leak, the problem only gets worse — fast.

The Bucket Test: Your First Check

Top Signs You Have a Leak

• Water level drops more than 2 inches per week
• Wet spots around the pool deck
• Cracks in the pool shell or deck
• Air bubbles in the return lines
• Constantly adding water (more than once per week)

Normal Evaporation vs a Leak

• Normal evaporation: 1/4 to 1/2 inch per week in summer
• Leak: 1+ inches per day, or consistent 2+ inches per week

When to Call a Pro

If the bucket test shows a leak — or if you see any of the warning signs above — it's time to call a professional. Early detection saves money on repairs and prevents structural damage.

• Pressure testing of plumbing lines
• Electronic leak detection
• Dye testing for precise location

Final Takeaway

A little water loss is normal in Austin summer. But if you're constantly refilling, there's a problem. The bucket test takes 5 minutes — use it before a small leak becomes a big repair bill.
