What is the difference between a water line and a sewer line?

A water line (supply line) carries clean water into your home, typically from the municipal meter. A sewer line carries wastewater away from your home to the city main. They're separate systems with different materials, failure modes, and repair methods. This page covers water line (supply) replacement, not sewer lines.

How do I know if my water line needs replacing?

Signs include a sudden drop in water pressure throughout the house, discolored water, recurring wet spots in the yard along the line's path, or a visible leak at the meter connection. We assess the line's condition to determine whether a repair or a full replacement fits your situation.

Does a water line replacement require digging up my yard?

It depends on your site and line. Access to the line from the meter to the home often involves excavation, but the extent and method depend on the line's depth, length, and path. Trenchless options for supply lines aren't automatically available for every line — they depend on site conditions. We explain the access plan and confirm what surface restoration is covered — and what you coordinate separately — in a written scope before work begins.

Is a water line replacement permitted?

Confirm applicable permits, inspections, and who is responsible for them before work starts. Water line replacements commonly require a permit and inspection, but requirements vary by jurisdiction and project. Ask for the permit plan and any inspection records in writing so you have documentation for your records.

Water Line Replacement in Los Angeles, CA

Your water line is the supply pipe that brings clean water from the municipal meter to your home — a separate system from your sewer line. When it fails, you may see pressure loss, discolored water, or wet spots in the yard. We assess the line and lay out the replacement scope, including access and restoration, before any work.

Supply Line, Not Sewer

It's important to distinguish the water line from the sewer line. The water line is pressurized and carries clean water in; the sewer line carries wastewater out. They fail differently and need different repairs. This page covers the supply (water) line from the meter to the home.

If your issue is drains backing up or sewage odors, that's a sewer line concern — we handle both, but the diagnosis and scope differ.

Signs Your Water Line May Need Replacement

Pressure & Flow

•Drop in pressure house-wide
•Discolored or rusty water
•Reduced flow at multiple fixtures

Visible Signs

•Wet spots in the yard
•Pooling near the meter
•Unexplained water bill increase

What We Assess

•Line condition and material
•Location of any failure
•Repair vs. replacement fit
•Access and restoration plan

Replacement Scope and Restoration

A water line replacement runs a new supply line from the meter to your home. We confirm the line's path, depth, and material before work, and explain the access required. The access method — excavation or, where suitable, an alternative — depends on your site and line, so confirm it in the scope. Restoration of the affected surface is something we clarify in writing, including any work you coordinate separately.

Permit and inspection responsibilities should be confirmed in the written scope, along with any documentation for your records.
