Overview
A single‑family residence in West Palm Beach experienced intermittent water meter movement even when the home’s main shutoff valve was closed. This indicated a potential leak on the exterior main line before it entered the structure. Southeastern Leak Detection was dispatched for two separate visits to diagnose the issue as it progressed.
Challenge
The primary challenge was locating a very small exterior main line leak that initially produced only a slow meter spin and minimal pressure loss. The main line ran beneath a large oak tree with extensive root systems, creating acoustic interference and limiting the effectiveness of leak detection equipment. As the leak worsened over time, conditions changed enough to allow for accurate pinpointing.
Inspection Process
During the first visit, technicians performed a full pressure test, confirming a minor leak with a pressure loss of approximately 1 lb per 5 minutes. Acoustic equipment was deployed along the accessible portions of the main line, but root interference and the small size of the leak prevented detection.
On the second visit, after the customer reported a faster meter spin, technicians redeployed acoustic equipment. With the leak now larger, clear acoustic signatures were present, allowing precise localization of the failure point.
Findings
The leak was pinpointed directly beneath the main line stub‑out, where the exterior main emerges to the shutoff valve before feeding the home. The failure was located in a tight, obstructed area adjacent to the exterior wall and the air‑conditioning unit. Due to the confined space and structural limitations, a standard excavation and spot repair would be difficult and potentially unreliable.
Recommended Next Steps
Technicians advised that the most reliable long‑term solution was to reroute the main line to a more accessible location. This avoids complications associated with repairing a leak in a restricted area and reduces future risk of failure. A new shutoff valve and hose bib were recommended as part of the reroute for improved accessibility and functionality.
Repair Process
The exterior main line was rerouted, abandoning the compromised section near the stub‑out. A new full‑port ball valve shutoff was installed in a safer, more accessible location, along with a new hose bib tied into the rerouted main. The new line was connected to the home’s service piping with proper fittings, pressure‑tested for integrity, and the work area restored to grade. See Our Leak Detection Services
