Drain cleaning in Los Angeles, CA
If one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.

Drain cleaning for Los Angeles homes
Kitchen drains clog with grease and food. Bathroom drains clog with hair and soap. Main lines in older neighborhoods clog with roots that grow into clay pipe joints. Each needs a different tool, so the first job is figuring out which one you have.

Local conditions
Drain cleaning in Los Angeles: what's different
Older Los Angeles homes have cast-iron drains that crack and scale up, and clay laterals that collect roots. Recurring clogs in pre-1960s homes in neighborhoods like Eagle Rock and Mid-City often point to one of these.
A plumber clears the line and recommends a camera inspection if the clog returns. LA Sanitation handles the public sewer; the lateral is the owner's responsibility.
Mature trees in neighborhoods like Silver Lake and Highland Park make roots in old clay laterals a recurring problem.

Other Los Angeles conditions that affect plumbing
- Galvanized and cast-iron pipe: Corroded galvanized supply and cracked cast-iron drains are the most common reasons for repiping and drain replacement.
- Earthquake readiness: California requires water heaters to be strapped against earthquakes, and flexible gas connectors reduce break risk.
- Hard water: Southern California water is hard, so scale builds up in heaters and fixtures.
- Water conservation rules: LADWP enforces watering-day limits during droughts, so leaking irrigation valves, running toilets and slab leaks show up quickly on bills. Many owners also switch to WaterSense fixtures, which California requires for new toilets and faucets sold.
How drain cleaning works in Los Angeles

A hand auger, a machine cable or a hydro jetter is used, sized to the pipe.
- 3

Water is run through the line to confirm it drains at full speed.

Why is my basement floor drain backing up?
When water comes up through the basement floor drain, the main sewer line is usually blocked between the house and the street. Stop using water upstairs, then call a plumber to clear the main line. If it happens more than once, a camera inspection shows the cause.

Should you get a sewer scope before buying a home?
For homes built before about 1980, or with large trees in the front yard, a sewer scope is worth it. A standard home inspection doesn't look inside the sewer line, and in most U.S. cities the buyer will own that line, often all the way to the main.
Emergencies
Sump pump not working? Causes and fixes
Check power first, then the float: if it's stuck against the pit wall the pump won't start. A pump that runs but doesn't empty the pit often has a frozen or clogged discharge line or a stuck check valve. If the pit is about to overflow, call right away.
