Residential water line replacement
When the whole line needs to go
A main water line is the single pipe that carries every gallon your household uses. When it is old, corroded or has failed more than once, repairing it again only delays the next leak. Residential water line replacement swaps the entire run between the meter and the house for new copper or PEX pipe, connected at both ends and pressure tested before the trench is closed.
Diamond Bar's first model homes went up at the north end of town in 1960, four years after Transamerica bought 8,000 acres of Brea Canyon ranch land, and building continued for decades after that. Many original lines here are now several decades old, and some neighborhoods nearby are older still. Water main pipe replacement on those homes often means taking out galvanized steel that has narrowed with rust, or older lines that have shifted in hillside and clay soils. Before we dig, we agree on a route that avoids the driveway where possible and a time for the shutoff that suits the household.
Warning signs
Is your main line failing?
Low pressure everywhere
Every faucet and shower is weak at the same time, not just one fixture.
A water bill that jumps
The bill climbs even though nothing about your household use has changed.
Soggy or extra-green patches
Wet ground or a strip of greener grass in an otherwise dry yard.
Rusty or cloudy water
Brown or discolored water at several taps often points to an old steel line.
A meter that keeps spinning
The meter dial moves even with every tap and appliance turned off.
Hissing or running sounds
You hear water moving in the walls or the ground when nothing is on.

FAQ
Main water line questions from Diamond Bar homeowners
How do I know the problem is my main water line?
Main line trouble usually shows up across the whole house: low pressure at every tap, a meter that moves with everything off, or a wet patch between the street and your home. A problem at one fixture is usually something smaller.
Can you come out today?
Usually, yes. We offer same-day service. Call, tell us what is happening, and we will set a time.
Do you answer the phone at night and on weekends?
Yes. Our phones are answered 24/7, so you can reach us at 2 a.m. on a Sunday if that is when the line fails.
Who is responsible for the pipe from the meter to my house?
In most local water systems the homeowner owns the line from the meter to the house, and the provider handles the meter and the street side. We can help you confirm your setup.
Why don't you list prices on the site?
Cost depends on the length and depth of the line, the pipe material, what sits on top of it and how easy it is to reach. We would rather look at your line than guess.
