How to Locate A Water Leak Under Slabs

Dealing with water leaks under a slab can be a homeowner’s worst nightmare. Not only can they cause significant damage to your property, but they can also lead to costly repairs if not detected early. In this blog, we’ll walk you through the steps to locate water leaks under slabs and how to detect slab leaks effectively.

Understanding Slab Leaks

A slab leak occurs when the plumbing pipes under the concrete foundation of your home develop leaks. Various factors, including poor installation, corrosion, ground movement, and natural wear and tear can cause these leaks. Identifying a slab leak early is crucial to preventing extensive damage to your home.

Signs of a Slab Leak

Before diving into how to locate a water leak under the slab, it’s essential to recognize the common signs that indicate you might have a slab leak:

1. 1. Unexplained Increase in Water Bills: A sudden spike in your water bill without any significant change in water usage can be a red flag.
   2. Damp or Warm Spots on the Floor: If you notice unusual dampness or warmth in certain areas of your floor, it might indicate a leak underneath.
   3. Mold or Mildew: Persistent moisture can lead to mold and mildew growth, which is often accompanied by a musty smell.
   4. Low Water Pressure: A decrease in water pressure could mean that water is leaking from the pipes under the slab.
   5. Sound of Running Water: If you hear water running or hissing even when all faucets are turned off, it could signal a leak.

How to Detect Slab Leaks

Detecting slab leaks requires a combination of observation and specialized equipment. Here’s a step-by-step guide on how to detect slab leaks:

1. Monitor Your Water Meter:
   • Turn off all water sources in your home, including faucets, appliances, and irrigation systems.
   • Check your water meter and note the reading.
   • Wait for about 15 minutes without using any water, then check the meter again. If the reading has changed, you likely have a leak.
2. Inspect for Water Damage:
   • Look for signs of water damage on your floors, walls, and baseboards. Pay attention to any unexplained dampness or discoloration.
3. Use Infrared Cameras:
   • Infrared cameras can detect temperature variations in your floors, which can indicate the presence of a leak. Warm spots might suggest a hot water line leak.
4. Perform a Pressure Test:
   • A professional plumber can perform a pressure test on your plumbing system to identify leaks. This involves shutting off the water supply and pressurizing the system with air to locate leaks.
5. Electronic Leak Detection:
   • Electronic leak detection equipment uses sensors and microphones to detect the sound of water escaping from pipes. This method is highly accurate and non-invasive.
