Overview
A historic multi‑structure property presented continuous water meter activity despite no water usage inside the home. Th
e homeowner requested a full leak detection assessment to determine the source of the unexplained water loss.
Challenge
The property’s age and complex plumbing layout created several diagnostic obstacles:
No functional home shutoff valve to isolate individual structures
Multiple generations of plumbing systems
A main house, guest house, and garage sharing interconnected supply lines
Crawl‑space access limitations beneath the older structure
Accurately identifying the leak location required a multi‑method diagnostic approach.
Inspection Process
1. Meter Verification Confirmed active meter movement with all fixtures off, indicating a pressurized line leak.
2. Crawl‑Space & Interior Assessment Inspected the original house crawl space and performed a full thermal imaging and moisture meter sweep throughout the main home. No visible leaks, heat signatures, or moisture anomalies were detected.
3. Plumbing Layout Analysis Mapped the functional plumbing configuration:
Cold water feeds the main house first
Line continues to the guest house/garage
Water heater located in the guest house
Hot water returns to the main house to supply fixtures
This clarified where a cold‑side leak was most likely occurring.
4. Acoustic Leak Detection Deployed acoustic equipment beneath the guest house crawl space. Strong leak signatures were detected, followed by visual confirmation of water bubbling through a floor grate.
Findings
All diagnostic evidence confirmed:
Active cold‑water leak beneath the guest house crawl space
Leak located on the cold‑water supply line feeding the water heater
No active leaks detected in the main house
No moisture or thermal anomalies inside the primary structure
Plumbing age and mixed generations contributed to system vulnerability
Recommended Next Steps
To restore reliability and eliminate future failures, the following corrective actions were recommended:
Install a functional main shutoff valve for proper isolation
Reroute and modernize water lines serving the guest house and garage
Remove abandoned or compromised plumbing segments
Pressure‑test all new lines after installation
Repair Process
A full plumbing reroute was performed to replace aging and compromised lines:
Located and exposed the main water line supplying the guest house
Verified condition of the existing main line
Eliminated outdated plumbing serving the guest house and garage
Installed new cold‑water line to the water heater
Installed new cold and hot water lines feeding the guest house bathroom
Conducted a full pressure test to confirm proper function and ensure no leaks
The property’s water system was restored to reliable operation with modernized piping and verified pressure integrity.
