Water Line Installation & Replacement in Sacramento County
Your main water line is the single pipe that delivers all the fresh water from the city meter to your home. When it leaks, breaks, or corrodes through, nothing inside works the way it should. 5-Star Plumbing Inc installs and replaces main water lines across Sacramento County. CSLB #1038276, licensed in both general building (B) and plumbing (C36) since 2018.
Signs Your Main Water Line Is Failing
The main water line runs underground from the city meter to your home — usually under the front yard, driveway, or walkway. Because it’s buried, problems develop invisibly until they become impossible to ignore:
- A sudden or steady drop in water pressure throughout the entire house.
- Water pooling in the front yard, driveway, or near the foundation — especially when no one’s using water inside.
- A water bill that spiked without any change in usage.
- Muddy, discolored, or sediment-filled water coming from multiple faucets.
- The sound of running water when all fixtures are off.
- Wet spots or erosion along the path between the meter and the house.
- The city has notified you of a leak on your side of the meter.
Sacramento’s clay-heavy soil expands and contracts with the seasons, putting constant stress on buried pipes. Galvanized steel lines installed in the 60s through 80s corrode from the inside, restricting flow long before they actually burst. If you’re seeing any of these signs, the problem is between the meter and your house — and it’s your responsibility, not the city’s.

Water Line Questions — Straight Answers
- How do I know the leak is in my main water line and not inside the house?
Turn off every fixture and appliance in the house, then check your water meter. If the meter is still spinning, the leak is between the meter and your home — that’s your main water line. If the meter stops, the leak is inside. Either way, we can diagnose it on-site.
- Is the main water line my responsibility or the city’s?
In Sacramento County, the homeowner is responsible for everything from the meter to the house. The city owns the pipe from the main in the street to the meter. If the leak is on your side of the meter, it’s your repair to make.
- What causes main water lines to fail in Sacramento?
Galvanized steel pipes corrode from the inside over 40–60 years, gradually restricting flow until they leak or burst. Sacramento’s clay soil expands in wet seasons and contracts in dry ones, stressing pipe joints. Tree roots can also damage lines at connection points. Most failures we see are in homes built in the 1960s through 1980s.
- Can you replace my water line without digging up the driveway?
In most cases, traditional open-cut excavation is required for water line replacement. During the on-site evaluation, we assess the best access route to minimize disruption to your driveway, walkway, and landscaping.
- What material do you use for the new line?
We use copper or PEX depending on local code requirements and site conditions. Both are durable, code-compliant options for Sacramento County.
- How long does a main water line replacement take?
Most line replacements take 1–2 days depending on line length and depth. Water is typically off for 4–6 hours during the connection phase — we’ll coordinate timing with you.
- Do I need a permit?
Yes. Sacramento County requires a plumbing permit for main water line work. If the line crosses a sidewalk or public right-of-way, an encroachment permit may also be needed. We pull all permits and schedule the city inspection as part of the project.
- Should I replace my pressure regulator valve (PRV) at the same time?
If your PRV is original to the house or hasn’t been replaced in 15+ years, a water line project is the ideal time. We’re already working at the entry point, so the added cost is minimal compared to a separate service call later. A failing PRV can cause water pressure that’s too high (damaging fixtures and appliances) or too low (weak flow throughout the house).
- Will my yard look the same afterward?
We keep disruption as small as the job allows — backfilling and compacting the affected area when we’re done. Full landscape restoration isn’t included (we’re plumbers, not landscapers), but we leave the surface ready for you or your landscaper to finish.
