Water Line Repair & Replacement in California

Main water service lines from the meter to the house repaired or replaced — including low-pressure fixes.

About Our Water Line Repair & Replacement Service

Your main water line carries every gallon from the meter to your house. When it leaks or clogs with corrosion, you'll notice low pressure, wet spots in the yard or a high water bill. Our California water line repair team locates the problem and repairs or replaces the line.

Water Line Repair & Replacement FAQs

Who owns the water line in California?

Typically the utility owns the line up to the meter and the homeowner owns it from the meter to the house.

How do I know if my main line is leaking?

Wet spots in the yard, low pressure and a meter that moves with everything off are the usual signs.

Can a water line be replaced without digging up the whole yard?

Often, yes. We can pull a new line through a narrow trench or by boring.

What pipe do you use for new water lines?

We use copper, PEX or HDPE depending on soil, local code and your preferences.
