Suspect a Slab Leak? Act Immediately

A slab leak occurs when a water line breaks beneath your home’s concrete foundation.
Left untreated, it can cause foundation damage, mold growth, and major structural issues.

If you think you have a slab leak, take action right away.

🚨 Step 1: Shut Off the Water Supply

Turn off your main water valve immediately to stop further damage.

• Usually located near the water meter or exterior wall

• Turn clockwise to shut off

👉 This prevents continuous water flow under your foundation.

⚠️ Step 2: Turn Off Your Water Heater

If the leak affects hot water lines:

• Shut down the water heater

• This prevents overheating or pressure buildup

🔍 Step 3: Look for Signs of a Slab Leak

Common warning signs include:

• Warm or hot spots on the floor

• Unexplained increase in water bills

• Sound of running water when fixtures are off

• Cracks in walls or flooring

• Moisture, mildew, or flooring damage

👉 Slab leaks are often hidden — early detection is critical.

🧹 Step 4: Minimize Interior Damage

If water is surfacing inside the home:

• Dry affected areas immediately

• Remove rugs, furniture, or flooring if necessary

• Use fans or dehumidifiers

The goal is to reduce moisture and prevent mold.

❌ Step 5: Do NOT Break the Slab Yourself

Avoid DIY attempts like:

• Jackhammering floors

• Guessing pipe locations

• Temporary patching

👉 Incorrect action can cause more structural damage and higher repair costs.

📞 Step 6: Call a Slab Leak Specialist Immediately

Professional plumbers use advanced tools to:

• Detect leaks without unnecessary demolition

• Identify exact pipe location

• Recommend the best repair method

Possible solutions include:

• Spot repair

• Pipe rerouting

• Full line replacement
