Overview
Southeastern Leak Detection & Repair was contacted to investigate a suspected underground leak at a single‑family residence in Hobe Sound, FL. The homeowner reported elevated water usage and meter activity despite no water running inside the home. Our team conducted a full diagnostic inspection using meter verification, excavation, acoustic testing, and camera‑scope confirmation to identify the exact leak location and provide actionable repair recommendations.
Challenge
The property exhibited clear signs of an active underground leak: the water meter continued spinning even with the home’s main shutoff valve closed. However, no visible water pooling or surface indicators were present, and the leak appeared to be located somewhere between the meter and the home’s main supply line — a zone often difficult to diagnose due to depth, soil conditions, and limited access.
The homeowner needed:
A precise leak location
Confirmation through multiple diagnostic methods
Documentation suitable for repair planning and insurance
Inspection Process
1. Meter Verification
The inspection began with a controlled shutoff test. With the house main valve fully closed, the water meter continued spinning, confirming an active leak on the supply line between the meter and the home. This ruled out interior plumbing and isolated the issue to the underground service line.
2. Meter Box Excavation
To eliminate the possibility of a failure at or immediately adjacent to the meter box, our technician excavated around the meter assembly. The exposed piping showed no cracks, corrosion, or joint failures. This step ensured the leak was not originating at the meter connection point.
3. Acoustic Leak Detection
Using a professional listening device, we performed acoustic testing along the service line path. Distinct leak signatures were detected near the main line, indicating water movement and pressure loss beneath the structure. This narrowed the search zone and guided targeted excavation.
4. Subsurface Excavation
Based on acoustic readings, excavation was performed under the side of the house. The leak was successfully located beneath the water main, approximately 6–12 inches back toward the structure. Soil conditions and pipe depth required careful digging to avoid further damage.
5. Camera Scope Verification
To provide definitive visual confirmation, a camera scope was deployed into the exposed section of piping. The video captured clear evidence of the leak and its exact position relative to the main line. This footage serves as both diagnostic proof and documentation for repair or insurance claims.
Findings
Active underground leak confirmed between the meter and the house main.
Leak located under the water main, positioned 6–12 inches back toward the home.
Meter box and surrounding piping showed no defects, eliminating that area as the source.
Acoustic testing and camera verification aligned, providing multi‑method confirmation.
Recommended Next Steps
1. Targeted Leak Repair
Excavate and repair the damaged section of pipe beneath the water main. Due to its position under the structure, repair may require trenching or tunneling depending on access.
2. Adjacent Pipe Assessment
Inspect nearby sections of the service line for early signs of corrosion or stress to prevent future failures.
3. Post‑Repair Validation
Perform pressure testing and acoustic verification after repair to ensure full system integrity and confirm no secondary leaks.
4. Documentation Retention
Maintain the camera‑scope video and inspection notes for insurance, permitting, or future reference.
Outcome
Southeastern Leak Detection & Repair successfully identified and verified a subsurface leak that had no visible surface indicators. Through a combination of advanced acoustic technology, strategic excavation, and camera‑scope confirmation, the homeowner received a precise diagnosis and a clear path forward for repair.
This case demonstrates our ability to locate difficult underground leaks with accuracy, efficiency, and thorough documentation — even in challenging access conditions.
