Main Water Line Repair & Replacement in Phoenix
The main water line between the meter and your house carries every drop your home uses. When it fails — from shifting desert soil, tree roots, or decades-old pipe — you'll see soggy spots in the yard, a spinning meter, or a sudden pressure drop. Simon locates the problem, repairs the line where repair is sound, and replaces it when the pipe is past saving.

Common problems Simon fixes
A water meter that never stops
With every fixture off, the meter should sit still. Movement means water is leaving the line somewhere between the street and your house.
Wet or sunken spots in the yard
A soggy patch or unusually green strip along the line's path is the classic sign of an underground leak in the main.
A sudden jump in the water bill
Main line leaks can run around the clock without a drop showing up inside the house — the bill is often the first warning.
Falling pressure through the whole house
Pressure loss at every fixture at once points to the main line, not an individual valve or faucet.
Old galvanized or polybutylene pipe
Homes still served by original galvanized or polybutylene mains are living on borrowed time — both fail with age, and replacement beats repairing failure after failure.
How it goes

Describe what you're seeing — a spinning meter, wet yard, or pressure drop — and get scheduled fast. Active leaks get priority.
Locate the leak
Simon traces the line and pinpoints the failure before any digging, so the excavation is as small as the job allows.
Repair or replace the line
Sound pipe with a localized failure gets a targeted repair. Deteriorated pipe gets a full replacement from meter to house, quoted upfront before any digging starts.

Frequently asked questions
How much does main water line replacement cost?
It depends on the line's length, depth, material, and what's above it (grass, hardscape, driveway). Simon quotes the full job upfront after locating the problem, before any digging starts.
How do I know if my main water line is leaking?
Shut off every fixture and watch the meter — if it's still moving, the line is losing water. Wet yard spots along the line path and a house-wide pressure drop are the other two classic signs.
Repair or full replacement — how do you decide?
Material and age decide it. A localized failure in otherwise sound copper or PEX earns a repair. Galvanized and polybutylene lines that have started failing will keep failing, and replacement is the honest recommendation.
Will my yard survive the work?
Simon pinpoints the leak before digging, so excavation stays as contained as the job allows, and he'll walk you through exactly where and how big before starting.
Is a main line leak an emergency?
An active leak wastes water constantly and can undermine hardscape and foundations, so it gets priority scheduling. If water is pooling fast, shut off at the meter and call any hour — Simon answers 24/7.
