Water leaks can be a silent threat to homes and businesses in San Antonio, TX, often causing significant damage before they are even detected. While visible leaks are easy to spot, hidden leaks require a more investigative approach. Identifying and addressing hidden water leaks promptly can save property owners time, money, and stress. Here’s how you can detect and fix hidden leaks like an expert.

Signs of a Hidden Water Leak

Not all water leaks are obvious, but some telltale signs can indicate an issue beneath the surface. If you notice any of the following, it’s time to investigate further:

• Unexplained Increase in Water Bills – A sudden spike in your water bill could be a sign that water is being wasted due to an unseen leak.
• Low Water Pressure—If water flow has decreased without a known cause, a hidden leak may be reducing pressure in the pipes.
• Stains or Discoloration – Brown or yellow spots on walls, ceilings, or floors can signal water accumulation behind surfaces.
• Warped or Buckled Flooring – Moisture from leaks can cause wood floors to warp or laminate flooring to bubble.
• Moldy or Musty Odors—A persistent damp smell, especially in enclosed areas, can be a sign of a hidden leak.
• Peeling or Bubbling Paint and Wallpaper – Moisture trapped behind walls can cause paint and wallpaper to lose adhesion.
• Dripping or Running Water Sounds – If you hear water running when all fixtures are turned off, there might be a hidden leak.

Finding Hidden Water Leaks

Once you suspect a leak, you’ll need to determine its source. Here are some effective methods for locating hidden leaks:

Check Your Water Meter

1. Turn off all water fixtures and appliances.
2. Check the water meter reading.
3. Wait for at least an hour without using any water, then check again.
4. If the meter has changed, you likely leak.

Inspect Walls and Ceilings

Look for discoloration, bubbling, or soft spots in drywall, as these can indicate hidden water damage.

Use a Thermal Imaging Camera

Professional leak detection often involves thermal imaging, which can reveal moisture behind walls without invasive inspections.

Conduct a Dye Test

For toilet leaks, add food coloring to the tank and wait 15 minutes. If the color appears in the bowl, the toilet has a silent leak.

Call a Professional

How to Address Hidden Water Leaks

Once you’ve identified a hidden water leak, it’s essential to take quick action to minimize damage. Follow these steps to effectively handle the situation:

1. Shut Off the Water Supply

If you locate the source of the leak, turn off the main water valve to prevent further water loss and damage.

2. Repair or Replace the Affected Pipe or Fixture

Depending on the severity, you may need to repair a small section of pipe, replace fittings, or call a professional plumber.

3. Dry Out Affected Areas

To prevent structural damage, use fans, dehumidifiers, and proper ventilation to dry out damp areas.

4. Inspect for Structural Damage

Water leaks can weaken wood, drywall, and insulation. A professional assessment can determine if repairs are needed.
