Water Line Repair & Replacement in Upland, CA
The water line from the meter or curb stop to your house is a different line from the plumbing inside your home, and a leak here shows up as low pressure or a wet spot in the yard rather than a fixture problem.

The water service line runs underground from the city's meter or curb stop to your house, separate from the interior supply lines a repiping job would address. A leak here often shows up as a wet or unusually green patch in the yard, or a water bill spike with no clear source inside the house.
We start with leak detection to confirm the line is the actual source before recommending repair or replacement, since a slab leak or an interior line issue can look similar from the symptoms alone.
Why Service Lines Fail In Upland
Older galvanized service lines, common in homes built before the 1960s, corrode internally over decades until a leak develops, often at a joint or a weakened section rather than uniformly along the pipe.
Tree roots can also intrude on a service line the same way they affect sewer lines, particularly on properties with mature trees near the line's path between the meter and the house.
Ground shifting on hillside properties in San Antonio Heights can stress a service line running at a steeper grade than a flat-lot installation.
All repair and replacement work follows the California Plumbing Code (UPC) requirements for service line material, depth, and connection to the meter.
Signs Of A Service Line Problem
Wet Or Unusually Green Patch In The Yard
Often the clearest visible sign of an underground service line leak.
Low Water Pressure Throughout The House
Can indicate a partial line failure restricting flow before it even reaches the house.
Meter Running With Everything Off
Points to a leak somewhere between the meter and the house, or inside the home itself.
Unexplained Water Bill Increase
Worth investigating with detection before assuming it's an inside issue.
Suspect A Service Line Leak?
We confirm the exact cause before recommending repair or replacement.
How We Diagnose And Fix It
Detect
Confirm the leak is on the service line, not elsewhere.
Assess
Determine repair vs. full replacement based on line condition.
Repair Or Replace
Spot repair or trenchless replacement depending on findings.
Test & Restore
Verify pressure and restore any disturbed landscaping area.
Minimizing Yard Disruption
Trenchless replacement can install a new service line with minimal excavation in many cases, which matters for landscaped yards or properties with hardscape over the line's path. Not every situation qualifies, which we confirm during the assessment.
What Water Line Repair & Replacement Costs In Upland
Exact quote after inspection, before any work begins.
Service line failure from age or root intrusion is generally not covered by homeowner's insurance, as it's considered gradual wear rather than a sudden event.
Common Questions
How do I know if it's the service line or something inside my house?
Leak detection tells us definitively. A wet spot in the yard between the meter and house is the clearest external sign, but we verify before quoting any work.
Can this be fixed without digging up my whole yard?
Often yes, through trenchless methods or a targeted spot repair once the leak is precisely located.
Does the water company own part of this line?
Typically the line from the street main to the meter is the utility's responsibility, while the meter to the house is the homeowner's. Check with the city of Upland's water utility for the exact boundary on your property.
Is this covered by insurance?
Generally not for gradual failure like corrosion or root intrusion, though check your specific policy for any exceptions that may apply.
