Why Choose Homewerx?

Your Water Main Is Your Responsibility

The water supply line from the city meter to your house belongs to you. When it leaks, breaks, or corrodes, the repair cost — including any street or sidewalk restoration — is the homeowner's responsibility.

Galvanized Water Mains Restrict Flow

Older galvanized steel water mains corrode internally over decades, reducing the pipe diameter from 3/4 inch to as little as 1/4 inch. The result is low water pressure throughout the house.

Polybutylene Water Lines Fail Suddenly

Homes built between 1978-1995 may have polybutylene (gray plastic) water mains that are prone to sudden, catastrophic failure. Replacement is recommended before failure occurs.

Water Main Leaks Often Go Unnoticed

A water main leak underground between the meter and the house can run for months without visible signs — just a slowly increasing water bill. Meter testing reveals the leak quickly.

Our Process

01

Leak & Flow Assessment

We test your water main for leaks using meter isolation and pressure testing, and measure flow rate to determine if internal corrosion is restricting supply.

02

Route Planning

We plan the new water line route — same path as the old line, or a new route that avoids obstacles, tree roots, and hardscape features.

03

Permit Coordination

Water main replacement in San Diego requires a permit and inspection. We handle the permit application, coordinate the inspection, and ensure the installation meets code.

04

Installation

We install the new water main — typically Type K copper or PE — with proper depth, bedding, and backfill. Connections at the meter and house are made to current code standards.

05

Testing & Connection

The new line is pressure tested before connection to verify integrity. Once tested, we connect to the house plumbing and restore water service.

06

Surface Restoration

We restore any disturbed landscape, walkways, or driveway surfaces to pre-work condition, including compacted backfill and surface patching or re-seeding.
