Professional Slab Leak Detection in San Diego County

Water leaks hidden inside your foundation or walls can cause serious damage if not caught early. Tri Express Plumbing uses advanced leak detection technology to find leaks fast — without unnecessary digging or wall damage.

We serve all of San Diego County including Chula Vista, La Jolla, Del Mar, Pacific Beach, Mission Valley, and surrounding areas.

Our Leak Detection Process

Step 1: Initial Assessment — We listen for sounds of water movement and check your water meter to confirm a leak.

Step 2: Acoustic Detection — We use sensitive acoustic sensors to pinpoint the exact location of the leak.

Step 3: Thermal Imaging — Infrared cameras detect temperature changes caused by water flow, confirming the leak location.

Step 4: Pressure Testing — We pressure-test your system to isolate which line is leaking (hot, cold, or sewer).

Step 5: Clear Recommendations — We explain exactly where the leak is, what caused it, and your repair options.

Types of Leaks We Detect

  • Slab leaks — Under your foundation
  • Drywall leaks — Inside walls
  • Water heater leaks — Tank or connections
  • Pipe corrosion leaks — Old galvanized pipes
  • Sewer line leaks — Breaks in sewer lines
  • Underground line leaks — Main water supply lines
How We Pinpoint Your Leak
Step 1: Visual Inspection — We inspect all accessible pipes, connections, and fixtures for visible signs of water damage or corrosion. Step 2: Acoustic Testing — We use sensitive acoustic sensors to listen for the sound of water escaping. This pinpoints the leak location without guessing. Step 3: Thermal Imaging — Infrared cameras detect temperature changes in walls and floors caused by water flow, revealing hidden leaks. Step 4: Pressure Testing — We isolate sections of your plumbing and test pressure to confirm which line is leaking.
