8 Warning Signs of a Slab Leak

Slab leaks are among the most expensive plumbing problems Tyler homeowners face. Hidden beneath your concrete foundation, they can go undetected for months—causing thousands in water damage and even foundation problems. Here's how to catch them early.

Sign 1: Unexplained Water Bill Increase

The most common first sign. If your water bill jumps 25%+ without any change in usage, suspect a leak. Tyler Water Utilities can help you check for unusual consumption patterns.

Sign 2: Sound of Running Water

When everything is turned off and the house is quiet, do you hear water running? This constant flow sound—especially at night—often indicates water escaping somewhere in your system.

Sign 3: Hot Spots on Your Floor

This is the telltale sign of a hot water line leak. Walk barefoot on tile or concrete floors. Warm or hot spots indicate heated water pooling under the slab. This is most noticeable in the morning before foot traffic.

Sign 4: Cracks in Walls or Foundation

Water undermines soil beneath your foundation, causing shifting and settling. Look for:

  • New cracks near doors and windows
  • Doors that suddenly won't close properly
  • Cracks in floor tiles or foundation
  • Uneven or sloping floors

Sign 5: Mold or Mildew Smell

Musty odors without a visible source often mean moisture trapped somewhere—potentially under your slab. Check corners, closets, and areas near exterior walls.

Sign 6: Low Water Pressure

If water is escaping through a leak, there's less pressure at your fixtures. Suddenly weak showers or slow-filling toilets can indicate a significant leak.

Sign 7: Wet Spots on Floors

Water seeping up through your slab may appear as:

  • Damp carpet that won't dry
  • Discolored spots on tile grout
  • Warping or buckling hardwood
  • Moisture under vinyl flooring

Sign 8: Running Water Meter

The simple meter test:

  1. Turn off all water in your house
  2. Check your meter (usually at the curb)
  3. Wait 30 minutes—don't use any water
  4. Check meter again

If the dial moved or numbers changed, you have a leak somewhere.

Why Tyler Homes Are Vulnerable

East Texas sits on expansive clay soil that shifts dramatically with moisture changes. This constant movement stresses pipes under foundations. Many Tyler homes built in the 1970s-1990s also have copper pipes prone to corrosion.

What to Do If You Suspect a Slab Leak

  1. Document the signs (photos, dates, water bills)
  2. Call for professional leak detection
  3. Contact your insurance company
  4. Don't attempt DIY repairs—slab leaks require professional equipment
