Who supplies water in Downey?

Downey gets its water from the City of Downey's own municipal water utility, according to the City of Downey water services. 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.

What kind of homes and plumbing does Downey have?

Downey is a large, established city with many 1940s to 1960s ranch homes and some older pre-war houses. Mature trees, older sewer laterals and original galvanized or early copper supply lines are all common. Age shows up in predictable ways: galvanized or early copper supply lines that corrode or develop pinholes, clay or cast-iron sewer laterals that crack or let roots in, and water heaters that are past their expected service life.

Plumbing questions in Downey

Do you cover my address in Downey?

Call (708) 350-9399 and ask. This site takes calls from Downey 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. Have your address or nearest cross streets ready, plus a short description of the problem and anything you've already shut off. You'll hear on the call whether your address and job are covered. If they aren't, you'll know right away, without waiting for callbacks.

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

Water in Downey comes from the City of Downey's own municipal water utility. 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 Downey?

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 Downey, 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.
