Suspect a water line leak?
We diagnose and repair water service line issues across Carson properties.
Low Pressure or Wet Yard Near the Street? It Might Be the Service Line
The water service line runs underground from the city's connection point, usually near the street, to your home's main shutoff valve. When it fails, from corrosion, ground shifting, or tree root pressure, it typically shows up as unexpectedly low water pressure throughout the house, an unusually wet or soggy area in the yard along the line's path, or a spike in the water bill.
This is a different pipe than the interior supply lines a repipe would address, and a different repair scope than a single fixture leak. We confirm the location and cause before recommending open trenching or a trenchless approach.
Signs of a Water Service Line Problem
Sudden Low Pressure Throughout the House
A drop affecting every fixture, not just one, often points to the incoming service line rather than interior plumbing.
Unusually Green or Wet Yard Patch
A soggy area along the line's likely path, even without recent rain, suggests a leak underground.
Rising Water Bill
A leaking service line can lose a significant volume of water before any sign appears above ground.
Sound of Water Running Underground
Sometimes audible near the leak location, particularly at night when ambient noise is lower.
Service Line Issues in Carson
Older water service lines in parts of Carson were installed using galvanized steel or, in some cases, older polybutylene material, both of which are more prone to failure than the copper or modern plastic piping used in current installations. Ground shifting, tree root pressure, and decades of gradual corrosion are the most common causes of a service line failure in this kind of older infrastructure.
Trenchless replacement, pulling a new line through the ground using the existing line's path as a guide, avoids digging a full trench across a yard or under a driveway, which matters a lot for homeowners with established landscaping or hardscaping they don't want torn up. It's not always possible depending on the specific site conditions and existing line's routing, but where it is, it's usually the less disruptive and comparably priced option.
We always confirm the exact cause and extent of a service line problem before recommending open trenching or trenchless repair, since the wrong approach for a given situation can end up costing more in the long run than doing it right the first time.

What Affects the Price of Water Line Repair & Replacement
We can't give an accurate number without seeing the job, but these are the real factors that move the price up or down.
Trenchless vs. open-trench
Trenchless replacement often costs comparably to open trenching while avoiding yard and driveway restoration costs.
Length and depth of the line
A longer or deeper service line takes more time and material to address.
Existing line material
Older galvanized or polybutylene lines sometimes reveal additional wear once work begins.
Trenchless Replacement vs. Open-Trench Repair
| Factor | Trenchless Replacement | Open-Trench Repair |
|---|---|---|
| Yard impact | Small entry and exit points only | Full trench along the line's path |
| Best for | Most standard service line replacements where site conditions allow | Sites where trenchless access isn't feasible |
| Timeline | Often a single day | Can take longer depending on distance and depth |
| Landscaping/driveway | Typically preserved | Often disrupted, may need restoration afterward |
Low pressure affecting the entire house, along with a wet yard patch or rising water bill, points toward the service line. Interior plumbing issues usually affect one area or fixture at a time.
A method of pulling a new line through the ground using the old line's path as a guide, avoiding a full open trench across your yard. It's not possible in every situation but is often less disruptive when it is.
Trenchless replacement is often completed in a single day for a typical residential line. Open trenching can take longer depending on distance and site conditions.
