Plumber kneeling in an excavated hole working on a buried water pipe

Main Water Line Repair

For a line with one bad spot: a split from a shifting root, a failed coupling or a pinhole leak near the meter. We open only the area we need.

Water pouring out of a broken pipe onto a flooded street

Emergency Water Line Replacement

When the main line bursts at night or water is pouring into the yard, this is the call to make. We answer 24/7 and send help the same day, nights and weekends included.

Pressure gauge and red valve on an outdoor water pipe

Water Line Leak Detection

For the leak you know is there but cannot see. We trace the line, narrow down the spot and give you a clear picture before any excavation starts.

New blue water main with valves laid in an open trench

Underground Water Line Replacement

For buried lines running under lawns, gardens, driveways and patios. We plan the route around what sits above the pipe and replace the run in one job.

Water shutoff valve cover in a concrete sidewalk near a home

Water Service Line Replacement

For the pipe between the meter and your house. We help you sort out which side is yours and which is the water provider's, then replace your side cleanly.

New plumbing supply lines installed in an open wall during a renovation

Water Line Rerouting

For lines buried in the wrong place: under a foundation, through tree roots or beneath a patio. We plan a new path around the obstacle and switch the water over to it.

Compact excavator digging a narrow trench beside broken concrete

Water Line Trenching

The digging behind every new main line. We handle narrow side yards, sloped lots and planted beds, and we restore the trench when the pipe is in.

Old gray steel water pipes and valves mounted on a brick wall

Galvanized Water Line Replacement

For older homes still running water through galvanized steel. We replace the corroded line with copper or PEX and bring back the pressure you have been missing.

Choosing a service

Repair, replace or reroute: which one fits

Most calls start with a symptom rather than a diagnosis. A spike in the water bill, a wet corner of the yard or a shower that barely runs could each point to a different fix. Here is how the services fit together.

What every water line job includes

Whatever the service, the basics stay the same. We explain what we found before starting, keep the dig as small as the job allows, pressure test new pipe before it is buried, and backfill and compact the trench so it does not sink later.

We have done this work from our Diamond Bar Boulevard office since 2005; read about us. We also tell you when a cheaper fix will do. A repair that buys a sound line many more years is often the better choice, and we would rather say so than sell a replacement you do not need.
