Pool Losing Water in Campbell, CA? How to Tell Evaporation vs. a Real Leak

If your pool is losing water in Campbell, CA, you’re not alone. One of the most common questions we hear is: “Is this just evaporation, or do I have a leak?” The answer matters, because small leaks can become expensive repairs if ignored.

This quick local guide helps Campbell homeowners separate normal water loss from real leak symptoms.

What’s Normal Water Loss?

Pools naturally lose some water from:

  • Sun exposure and warm temperatures
  • Wind across the water surface
  • Splash-out from swimmers
  • Filter backwash cycles

But frequent top-offs or rapid level drops usually signal a leak.

Run a Simple Bucket Test at Home

The bucket test is the fastest first step:

  1. Fill a bucket with pool water.
  2. Place it on a pool step so water sits both inside and outside the bucket.
  3. Mark both levels.
  4. Wait 24 hours (avoid heavy pool use).
  5. Compare the drops.

If pool water outside the bucket falls more than the bucket water, leakage is likely.

Common Leak Clues in Campbell Pools

Wet Spots Near Decking or Equipment

Persistent moisture around pipes, pads, or hardscape can suggest underground line loss.

Cracks at Skimmer and Return Fittings

Movement and age can create leak paths at penetration points.

Constant Chemical Drift

If sanitizer and balance won’t hold, fresh water replacement from leakage may be diluting your chemistry.

Rising Utility Bills

Leaks waste water continuously, especially when unnoticed for weeks.

Why Early Leak Detection Saves Money

A minor leak can quietly cause:

  • Soil washout beneath decking
  • Surface cracking and settlement
  • Increased equipment strain
  • Ongoing chemical and water costs

The earlier you isolate the leak source, the more precise and affordable the repair tends to be.
