Water leaks cause over $13 billion in property damage every year in the U.S. alone.

Let’s dive in—before the next drop costs you thousands.

1. What Is Leak Repair? (And Why It Matters More Than You Think)

Leak repair is the process of identifying, diagnosing, and fixing any unintended flow of water, gas, or air through cracks, holes, or defective plumbing components.

Why does it matter?

• Water damage is the # 1 insurance claim for homeowners in the U.S.

• One leaky faucet can waste over 3,000 gallons of water a year.

• A leak left unrepaired can devalue your property by 10% or more.

Power Insight:

Leaks don’t just waste water—they erode the value and safety of your property. Fast action = long-term savings.

2. Top 7 Most Common Types of Leaks—And How to Spot Them

Knowing where leaks happen most often gives you a powerful advantage. Here are the usual suspects:

1. Toilet Leaks

• Often silent, but a running toilet can waste 200 gallons per day.

• Spot by adding food coloring to the tank—if it seeps into the bowl without flushing, you've got a leak.

2. Faucet & Shower Leaks

• Dripping sounds are obvious.

• A worn-out washer or corroded valve is usually to blame.

3. Pipe Leaks (Under Sinks or Behind Walls)

• Watch for mold, warped wood, or musty smells.

• Copper or galvanized pipes are more prone to corrosion over time.

4. Slab Leaks

• Hidden beneath the foundation—extremely dangerous.

• Signs: warm floor spots, cracks in flooring, high water bills.

5. Roof Leaks

• Often show up after storms or heavy snow.

• Indicators: ceiling stains, peeling paint, or attic mold.

6. Appliance Leaks (Water Heaters, Dishwashers)

• Pooled water or rust near the base = red flag.

7. Irrigation System Leaks

• Soft spots in your lawn or a dramatic rise in your water bill could point to an underground leak.

  More Frequently Asked Questions (FAQs) About Leak Repair
