Main water line repair and replacement in Sacramento, CA
The pipe from your meter to the house is yours, and when it leaks you pay for every gallon.

We find leaks on the service line, repair a single break, or replace the full line from the meter to the house in copper or polyethylene, often by boring under walkways and lawns instead of trenching.
What water line replacement covers
Your water service line runs from the meter at the street to the house, usually 2 to 3 feet deep. Older lines may be galvanized steel or early plastic, and they fail with leaks, low pressure or a sudden break that floods the yard.
For one leak on a newer line, a section repair is the right fix. For an old line or several leaks, replacing the whole run is cheaper long-term. We often pull or bore the new line under concrete to keep the yard intact.

Water Line Replacement in Sacramento: what we see locally
Across Sacramento, the city's metered water system puts the meter box at the front of the lot. Everything on the house side is the owner's to maintain, including the line under the lawn and walkway.
The line from the meter to the house is the owner's, and a full replacement often fixes low pressure everywhere.
Older homes in North Sacramento, Oak Park and Del Paso Heights still turn up galvanized service lines. Replacing one usually fixes low pressure throughout the house at once.


What you can safely do before we arrive
- Locate the meter box and the main shutoff.
- Move vehicles off the line route.
- Mark sprinkler lines and lighting.
Water Line Replacement questions
Who is responsible for the water line?
The utility owns the meter and the line to it. The homeowner owns the line from the meter to the house.
Can you replace it without digging up my driveway?
Usually, yes. We bore under concrete and pull the new line through.
Should I also replace the main valve?
Often, yes. It is a cheap upgrade while the line is open. See shutoff valve replacement.
