Water Line Problems We Repair Across San Jose
Not every water line problem looks the same, and not every fix is the same either. Here’s what we handle most often for homeowners and property managers across San Jose.
Water Line Leak Detection
Before any repair starts, we find the leak. Using acoustic sensors and pressure testing, we pinpoint the exact location of the break without tearing up your entire yard or driveway. Leak detection is the first step in almost every job we take on, and it’s the difference between a targeted repair and an expensive guessing game.
Underground Water Line Leak Repair
Left alone, an underground leak gets worse, not better. Constant moisture wears down the soil around the pipe, pipe corrosion sets in, and eventually the ground above it can sink or crack a driveway. We dig only where the line is actually damaged, patch or replace that section, and leave everything else untouched.
Main Water Line Repair
When the main water line supplying your entire property fails, water pressure drops everywhere at once — sinks, showers, irrigation, all of it. We repair breaks in the main water line quickly, because this isn’t a line you can live without for long.
Water Service Line Replacement
Some lines are too far gone to patch. If your service line is made of aging galvanized pipe or shows repeated failures, full water service line replacement is usually the smarter, cheaper option in the long run.
Trenchless Water Line Replacement
Digging up an entire yard to fix one bad section of pipe is overkill, and trenchless replacement skips it. We pull a new line through the path of the old one, so there’s no trench running the length of your property — just a couple of access points and a lawn that survives the job. It’s the option we reach for when a broken water line runs under a driveway, patio, or mature landscaping you’d rather not tear up.
Signs Your Main Water Line May Be Leaking
Most water line leaks don’t show up as a geyser in your front yard. They show up as smaller changes you might miss unless you know what to look for.
Repair or Replace? The Condition of the Pipe Decides
The right call between repair and full replacement comes down to pipe material, age, and how many times the line has already failed. Here’s a quick breakdown.
| Pipe Material | Typical Lifespan | Repair or Replace |
| Copper pipe | 50+ years | Usually repairable if damage is localized |
| Galvanized pipe | 20–50 years | Often needs full replacement due to internal corrosion |
| PEX | 40–50 years | Repairable; replacement rare unless installation was faulty |
| Old cast iron or steel | 25–50 years | Typically replaced, not repaired |
Water line work touches both plumbing rules and property boundaries. A few things are worth knowing before a crew shows up.
Who Is Responsible for the Line After the Water Meter?
In San Jose, the property owner is responsible for everything from the water meter to the house. San Jose Water or the municipal utility maintains the line up to the meter; anything past that point, including repairs or a full water line repipe, is on you.
When a Plumbing Permit and Inspection Are Required
San Jose requires a plumbing permit and a city inspection for most water service line replacement jobs, and the inspection has to happen before the trench gets backfilled. Skip it, and it can come back to bite you later — particularly if you’re selling the house down the road. We handle the permit and schedule the inspection ourselves, so it’s one less thing on your plate.
From Leak Check to Final Pressure Test
Every project follows the same process, whether it’s a small repair or a full water line replacement.
