A hidden water leak may seem minor, but it can quietly cause thousands of dollars in water damage, compromise your home’s foundation, and lead to mold, mildew, and even electrical hazards. As summer turns to fall and late-season storms increase humidity, it’s essential to stay alert to changes in your home’s plumbing system.
At Drain Terrier, we specialize in professional leak detection in Littleton, CO, using advanced tools like thermal imaging, infrared sensors, and moisture meters to detect water leaks behind walls, under floors, and even inside your attic or basement. Here’s how to spot hidden leaks before they result in property damage, sewage contamination, or costly restoration services.
7 Warning Signs of a Hidden Leak
Whether the issue stems from a damaged pipe, toilet, sink, or even your washing machine, knowing the signs of a hidden water leak can help you take action fast.
1. Unexplained Spike in Water Bill
If your water supply usage is climbing and your habits haven’t changed, you might have a leak behind your walls or under the floor. A running tap, leaking valve, or compromised water heating line could all be culprits.
2. Musty Odors or Mildew
Hidden leaks often cause excess moisture, creating the ideal environment for bacteria, fungus, and mildew to thrive. This can quickly reduce indoor air quality and even affect upholstery, carpet, and wood floors.
3. Water Stains or Bubbling Paint
If you spot a leak in your ceiling, warped building material, or stains on your walls, there may be a slow roof leak or pipe leak at play. Ceiling water damage and roof leaks in heavy rain are especially common in older homes.
4. Low Water Pressure
Decreased water pressure in your shower, bathtub, or kitchen faucet may be caused by a leak diverting flow elsewhere. Issues like corrosion, mineral buildup, or a burst pipe could also be contributing factors.
5. Sounds of Running Water
If you hear water running when all fixtures are off, it’s time to check for leaks. Hissing, dripping, or bubbling sounds may indicate hidden water intrusion behind drywall or under flooring.
6. Standing Water or Wet Spots
Unexpected puddles, damp soil, or basement leaks when it rains can point to issues with drainage, a failed sump pump, or outdoor irrigation leaks.
7. Mold or Health Symptoms
Chronic cough, allergies, or respiratory issues? Hidden leaks can contribute to pathogen growth and contamination, putting your family’s health at risk.
DIY Leak Detection Techniques
Before calling a plumber, here are a few ways to find a leak on your own.
Check the Water Meter
Turn off all water-using appliances and fixtures, then monitor your water meter. If it continues to move, there’s likely a leak.
Perform a Toilet Dye Test
Add food coloring to your toilet tank and wait 15 minutes. If the color appears in the bowl without flushing, you’ve got a leaking flapper or valve.
Use a Moisture Meter or Smart Leak Detector
A moisture meter can help detect water leaks in walls or under floors. For added protection, install a smart water leak detector near your water heater, ducts, or electronics for early alerts.
Protecting Your Property from Water Damage
Undetected leaks can lead to:
- Structural wood rot and drying issues
- Insurance claims through the National Flood Insurance Program
- Emergency flood damage or fire damage restoration
- High basement leak repair costs, ceiling water damage repair, or roof repair
Preventative steps like waterproofing, regular home inspection, and plumbing maintenance can help mitigate risk and reduce the chance of an emergency backup, flood, or natural disaster–related damages.
