What this site is

WaterMainCall is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands, and work on a service line is normally permitted and often coordinated with the utility — ask to see the permit. We carry out no work, we test no water, we do not set prices, and we never charge homeowners anything. Nothing here is a statement about the water at any address.

Checking a credential in California

California licenses are issued by the Contractors State License Board, which publishes a public search you can use before work begins. California licenses the C-36 plumbing contractor; there is no state journeyman license.

What that coverage looks like

Our California footprint is 1,921 ZIP codes in 40 counties, and Los Angeles County is the largest single part of it at 494. Every one of those counties contains more than one water supplier, and the line between the utility's pipe and yours is drawn by whichever one serves your meter.

How a water line repair job goes

A service line repair starts with a question of ownership. The utility is responsible up to a point written into its own policy — usually the main, the curb stop or the meter — and the homeowner from there. Finding the leak is one job; establishing which side of that line it is on is what decides who pays, and it is worth settling before the excavator arrives.

What the call asks about water line repair

Where the water is surfacing, and whether it is between the meter and the house or on the street side.
Whether the meter is in a pit at the boundary or on the wall of the house.
Whether the utility has already been out and said whose side it is on.

Every California city we route in

413 cities, ordered by the share of homes their owners live in. The older and denser the street, the older the service line running under it. Each page carries that city’s own numbers and the ZIP codes we route there.

Before you call

Which side of that line a leak is on decides who pays for it. The pages above say how to find out before the digging starts.
