How to Detect a Slab Leak

Why This Matters

A slab leak is a pipe beneath your foundation that cracks or bursts. They're hidden and dangerous.

Key Signs to Watch For

• Warm spots on floor: Hot water line leaks create warm areas.
• Cracks in walls/floors: Water undermines foundation.
• Sound of running water: Hear water when nothing is on.
• High water bill: Unexplained increase.
• Moisture or mold: Dampness at base of walls.

What You Should Do

1. Turn off all water — Check if meter continues moving.

2. Monitor water bill for unexplained increases.

3. Walk barefoot — Feel for warm spots.

When to Call a Professional

Slab leak detection requires specialized equipment. A plumber uses electronic listening devices, pressure testing, and camera inspection. Repair options include tunneling, breaking through floor, or rerouting.
