Drain cleaning in Torrance

In 1950 Torrance had 22,241 residents. By 1960 it had 100,991. Most of the houses we see in the city went up inside that window, and the sewer laterals under them are now more than sixty years old. If you own one, our areas we cover hub gives the wider picture, and this page narrows it to Torrance's own rules and problems.

Why do so many Torrance houses have the same drain problems?

Because they were built together. The Census profile puts the typical Torrance home at 1964, and just over half of the city's 59,284 homes are detached houses. Houses built in the same years tend to share lateral materials and street trees, so a problem on one lot is worth checking for on the next.

Torrance's Wikipedia entry says the city was laid out in 1912 on a plan by Frederick Law Olmsted Jr. as a planned industrial town. Old Torrance, the original downtown, is the oldest part of the city. At a median home value near $1.07 million, owners here tend to ask us about replacing a failing lateral for good instead of clearing it again and again. Our guide to pipe lining versus replacement helps with that decision.

Does Torrance fix a sewer lateral if a city tree caused the damage?

Sometimes, but the bar is high. The city's utility billing FAQ says the Streetscape Division does not remove city trees over sewer problems, because removal does not cure the pipe. The city pays for lateral damage only if the line has been exposed and inspected and a Streetscape supervisor confirms a city tree caused it.

The same FAQ rules out roots from a private yard or a neighbor's tree, and trees removed more than five years earlier. In other words, keep the camera footage and do not dig or replace anything before the city has seen the exposed pipe. Claims for lateral damage go through the City Clerk's Office or Risk Management according to the city. To find out what species stands in front of your lot, ask the city's Streetscape Division.

Our page on signs of tree roots in a sewer line lists what to look for, and how to get rid of roots in a sewer line covers the cutting options.

If a camera has shown roots in your lateral, request a written quote and we will arrange a visit with the footage in hand.

What permits does Torrance require for lateral work?

Torrance asks for two permits, depending on where the work happens. A Plumbing Permit, listed as Alter Building Sewer, covers repairs on private property from the building to the property line. A Construction and Excavation Permit covers work in the public right of way, from the property line to the sewer main. A job that crosses the line needs both.

The city defines the lateral as starting roughly one foot outside the building and running to the public main, and it holds the owner responsible for the whole of it, including the connection to the main. It recommends hiring a plumber with a state contractor license, getting a camera inspection, repairing what the camera finds and taking out permits before starting. The Community Development Department, at (310) 618-5910, confirms which permits apply.

What does Torrance charge for sewer service, and who runs the mains?

The City of Torrance maintains 287 miles of city-owned sewer line and 9 lift stations through its Wastewater Program. For 2026, the city lists a single-family charge of $0.46 per hundred cubic feet of water use plus a $4.86 fixed monthly charge. The city describes it as the charge for its sewer system, and it does not cover your private lateral.

If the camera shows your backup is in the public main, report it to the city at (310) 781-6900 or through the city's online service request. If the blockage is on your side, the lateral is yours to fix.

The result is a two step habit we recommend: camera first, then the right phone call. See our sewer line repair cost page for what a lateral repair involves once you know where the damage sits.

Is Torrance water hard, and where does it come from?

Torrance's 2025 water quality report does not publish a hardness figure, so we will not guess one. It does say the city bought 68 percent of its potable water from the Metropolitan Water District and drew the remaining 32 percent from the West Coast Groundwater Basin and a groundwater treatment project.

If you are curious about scale in your pipes, a home test kit or a call to your water supplier gives a number for your own address.

What about homes on slopes in Torrance?

Torrance borders the Palos Verdes Hills to the south, and the city has hillside areas. We have no Torrance-specific data on how slope affects laterals, so treat this as a reason to ask for a camera inspection of a sloped lot, not as a rule.

For apartments and commercial buildings in the city, the process is the same, but a commercial drain cleaning job usually involves a larger line and a scheduled visit.

Questions people ask

How much does drain cleaning cost in Torrance?

Torrance prices follow the pipe, not the postcode. A short, open run is a smaller job than a sixty year old lateral that needs a camera and a jet. Typical ranges are on our drain cleaning cost page, and a written figure reaches you before anyone starts.

Who is responsible for the sewer lateral in Torrance?

You are. The city's policy says property owners maintain and repair their lateral, which means the whole pipe on private property and the connection to the city sewer. The city maintains the main in the street. Camera footage tells you which side a blockage is on.

Do I need a permit to repair my lateral in Torrance?

For a repair, yes. Work on private property needs a Plumbing Permit, and work between the property line and the main needs a Construction and Excavation Permit. Ask the Community Development Department before starting, because a repair that crosses the property line needs both.

Will the city cut down the tree that is clogging my sewer?

No. The Streetscape Division says it does not remove city trees for sewer problems, and removal would not fix the pipe anyway. The city may cover repair costs in a narrow set of cases, so keep your camera footage and talk to the city before any digging.
