Before diving into detection methods, it’s essential to know what a slab leak is. These leaks occur in the water lines running below the concrete slab foundation of a house. They can be caused by various factors, including pipe corrosion, shifting ground, poor installation, or abrasion from prolonged contact with concrete or gravel.

While detecting a slab leak isn’t always straightforward, there are some telltale signs:

• Unexplained spikes in water bills
• Sound of running water when pipes aren’t in use
• Warm spots on the floor
• Cracks in walls or flooring
• Mildew or excessive moisture under carpets

There are several leak detection techniques that professionals use to locate slab leaks. These include:

• Electronic Leak Detection Equipment:  Plumbers use specialized electronic listening devices that amplify the sound of water escaping from pipes. This method is non-invasive and can accurately pinpoint the location of a leak under the slab.
• Infrared Cameras: These cameras detect temperature variations in the floor. Since water from the leak can change the temperature of the concrete, infrared cameras can reveal the location of the leak. It’s a quick way to identify the affected area and is also non-invasive.
• Pressure Testing: Plumbers isolate different sections of your plumbing system and use pressure gauges to identify where the water loss is occurring. This method is highly effective in determining if a leak is present in a particular section of piping.
• Pipe Tracing and Locating Equipment: This involves sending an electronic signal through the pipe and tracing its path with a receiver. This method is useful for mapping the plumbing layout and pinpointing the leak's location, especially for complex plumbing networks.
• Hydrostatic Testing: This method involves plugging the drain and filling the system with water. Observing how the water level changes can help determine if there's a leak. It’s particularly effective for identifying leaks in drain lines under the slab.

While some homeowners may attempt to identify slab leaks themselves, professional assessment is vital. Trained plumbers have the experience and tools necessary to detect these leaks accurately, minimizing the risk of unnecessary excavation or damage to your property.
