Who supplies water in Los Alamitos?

Los Alamitos gets its water from Golden State Water Company's West Orange County system, which blends local groundwater with imported water, according to the Golden State Water Los Alamitos system. The water provider owns and maintains the meter and the pipes on the street side of it. The service line from the meter to the house, and everything inside, belong to the property owner. So when there's a leak, the first question is which side of the meter it's on. A leak at the meter box or in the street goes to the water provider. A leak in the yard, the slab or the walls is a private plumbing repair.

Plumbing questions in Los Alamitos

Do you cover my address in Los Alamitos?

Call (708) 350-9399 and ask. This site takes calls from Los Alamitos and the other cities around Lakewood, but we don't list any ZIP code as guaranteed coverage, because availability depends on the provider, the type of job and timing.

Who do I call about a leak at the water meter in Los Alamitos?

Water in Los Alamitos comes from Golden State Water Company's West Orange County system, which blends local groundwater with imported water. Leaks at the meter, at the meter box or in the street belong to the water provider, so contact them first. Your bill names the provider. If the meter keeps moving after you've closed the house shutoff, the leak is probably in the buried service line between the meter and the house, which is the owner's responsibility. Leaks inside the house, in walls or under the slab are private plumbing repairs, and leak detection can find them with less digging.

Do I need a permit for plumbing work in Los Alamitos?

Often, yes. Replacing a water heater, repairing or replacing a sewer lateral, repiping and many other alterations usually need a permit from the local building department in Los Alamitos, and an inspection after the work. Minor repairs, like replacing a faucet cartridge or clearing a clog, generally don't. Ask the provider whether the permit is included and who arranges inspections. If you're doing any work yourself, check with the city's building department first. The city's official website is a good starting point.
