Main Water Line Repair & Replacement in Hanford
The underground main water service line connects the City of Hanford water meter box near the street or sidewalk to your home's main shutoff valve. Over decades, this pressurized line is subjected to tree root intrusion, ground settling from agricultural irrigation cycles, and external soil corrosion. When the main line cracks or shears, homeowners notice pooling water on their lawn, sinkholes, low household water pressure, or a water meter leak indicator dial spinning continuously. We repair and replace damaged underground water lines using trenchless boring or targeted excavation, installing heavy-duty copper or poly supply lines built to last.
Meter Dial & Pressure Testing
We perform static pressure tests and meter leak-detector evaluations to verify the exact underground loss rate between meter and house.
Underground Pipe Tracing
Electromagnetic line locators trace the exact underground path and depth of your service line to avoid utilities and minimize excavation.
Code-Approved Materials
We install thick-wall Type K soft copper or 200 PSI CTS polyethylene pipe bedded in clean sand to resist soil movement and corrosion.
Main Line Standards

How We Complete Your Service
- Meter Isolation & Leak Diagnostic: We test the city meter dial with the house valve closed to confirm the leak is in the yard service lateral, checking pressure drop over time.
- Line Locating & Utility Coordination: Our technician traces the path of the water line and verifies underground utility clearances (DigAlert 811) before any excavation commences.
- Targeted Excavation & Pipe Repair: We excavate the damaged section, remove the fractured pipe, and install heavy-duty brass compression couplings or pull a new continuous line.
- Full Pressure Verification & Soil Compaction: The line is pressurized, tested for zero pressure loss, cushioned with clean bedding sand, backfilled, and neatly tamped to restore your yard grade.
