How to Detect a Slab Leak Yourself in Longview, TX

Can You Detect a Slab Leak on Your Own?

While pinpointing the exact location of a sub-slab leak under concrete requires specialized acoustic hydrophones and thermal imaging cameras, homeowners in Longview, TX can easily perform a series of DIY checks to confirm whether a subterranean leak is currently active on their property.

Method 1: The Water Meter Test (100% Reliable DIY Check)

Your municipal water meter is the most accurate diagnostic tool available for preliminary leak testing:

1. Shut off all water fixtures: Turn off all indoor faucets, showers, toilets, ice makers, and outdoor garden hoses. Do not use washing machines or dishwashers.
2. Locate your water meter box: In Longview TX, municipal water meters are located near the curb in concrete or plastic boxes with iron lids.
3. Inspect the leak indicator: Open the meter cover. Look for a small red or blue triangle, star, or gear called the "low-flow leak indicator." If this dial is spinning even slowly while all fixtures are off, water is flowing into your plumbing system.
4. 30-Minute Static Reading: If your meter has a digital display, record the exact meter number. Wait 30 minutes without using any water. Check the meter again. If the number has increased, you have an active plumbing leak.

Method 2: Barefoot Floor Surface Thermal Walkthrough

Remove shoes and socks and walk slowly across all tiled, carpeted, and hardwood floor areas—especially in bathrooms, hallways, utility rooms, and kitchens. If you feel a distinctly warm spot on the floor surface, a hot water sub-slab line leak is transferring heat upward through the concrete slab pad.

Method 3: Water Heater Isolation Test

To determine if a detected leak is on the hot or cold water supply line:

• Locate the shut-off valve on the cold water inlet pipe above your water heater tank.
• Turn the valve clockwise to close off hot water supply to the home.
• Re-check your water meter. If the leak indicator dial stops spinning immediately, the leak is located on your hot water sub-slab line. If it continues spinning, the leak is on the cold water main.

When to Call a Professional Diagnostic Specialist

DIY tests verify *if* a leak exists, but cannot show *where* under the slab the break is located. Attempting to dig or break concrete based on guesswork can ruin flooring and damage surrounding electrical conduits. Once your water meter confirms an active leak, call ClearTrace Leak Detection at (903) 857-1070 for non-invasive pinpointing.
