How to Detect & Fix a Hidden Water Leak Before It Causes Major Damage

Jul 25

🚨 Why Hidden Leaks Are a Silent (and Expensive) Threat

Not all leaks come with a dripping faucet or a puddle on the floor. Some sneak behind walls, under floors, or in your foundation—causing thousands in water damage before you even know there’s a problem.

In fact, the average household leak wastes nearly 10,000 gallons of water per year, and insurance claims from water damage average over $11,000.

That’s why at In A Flash Heating and Plumbing, we help homeowners spot and stop leaks fast—before they cost you.

🕵️‍♂️ 5 Signs You May Have a Hidden Water Leak

Unexplained Spike in Water Bills
Notice your bill going up but your usage hasn’t? That’s a classic red flag.
Musty Odors or Mold Growth
Mold thrives where water hides. If you smell mildew but can’t find the source, check behind walls or under floors.
Stained or Warped Walls & Ceilings
Brown rings, bubbling paint, or soft drywall usually means water’s lurking.
Sound of Dripping or Running Water
Hear water when everything’s off? That could be a leak in the pipes behind your walls.
Cracks in Foundation or Floors
Slab leaks (under the concrete) cause subtle shifting and cracks over time.

🔧 How to Check for Leaks (Before You Call a Pro)

You don’t need to tear up your walls—here are a few DIY checks:

The Water Meter Test:
Turn off all water in your home. If your water meter is still moving after 15 minutes, you’ve got a leak.
Food Coloring in the Toilet Tank:
Put a few drops in the tank—if it appears in the bowl without flushing, you’ve got a silent toilet leak.
Thermal Cameras (if you have one):
These can spot cold spots behind walls where water may be leaking.
