Main water line repair and replacement in Los Angeles

The main water line runs underground from the meter at the street to your house. When it leaks or corrodes, you lose water pressure and pay for water you never use.

What needs fixing?

Your side of the meter

The water company owns the meter and the pipe on the street side of it. The line from the meter to your house is yours, and in older homes it’s often galvanized steel that has been rusting inside for decades.

A leak in this line can be hard to spot because the water soaks into the ground. Common clues are a wet spot in the yard, a water bill that keeps climbing, or low pressure everywhere in the house.

Main water line repair questions

Who is responsible for the water line, me or the city?

Usually the water company is responsible up to and including the meter. The line from the meter to your house is the homeowner’s responsibility.

Will a new water line give me better pressure?

If your old line is narrowed by rust, replacing it often makes a big difference. If the pressure is low coming from the street, a new line won’t change that, and we’ll tell you before you spend money on it.

How long does a main line replacement take?

Most are done in a day or two, depending on the length, the depth and what’s on top of the line.
