TL;DR: A sewer backup, water or waste coming up through more than one drain or a gurgling toilet, means the main line is blocked, not just one fixture. Stop using water in the house right now, locate the sewer cleanout outside, and call a licensed plumber to run a camera and clear the line. In Bakersfield, mature tree roots, grease buildup, and old clay or cast-iron pipe are the usual culprits. The city only maintains the main line under the street; the lateral pipe running to your house is your responsibility.
If water backs up out of your bathtub drain every time someone flushes the toilet down the hall, or two or three drains are gurgling and running slow at the same time, this is not a simple clogged line. That pattern points to a blockage in the main sewer line that serves the whole house, the pipe that carries everything out to the street. Stop running water anywhere in the house right now, and keep reading. Here is how to tell whether this needs a drain cable or a full camera inspection, and who actually owns the pipe causing the problem.
Is this a sewer backup or just a clogged drain?
A clogged drain affects one fixture; a sewer backup affects several fixtures at once, often with gurgling sounds from a toilet or floor drain when you run water somewhere else in the house.
If only your kitchen sink drains slowly, that is a localized clog, usually grease or food debris in the branch line, and a plunger or a basic auger handles it. But if flushing the toilet makes the shower drain bubble, or water rises in the tub when the washing machine drains, the blockage sits downstream of where those lines join, in the main sewer line. Every fixture connected to that line backs up at once because they all share the same exit point.
In older Bakersfield neighborhoods like Oleander, Westchester, and parts of East Bakersfield, where homes still run on original cast-iron and clay drain lines, this main-line pattern shows up more often than it does in newer construction with plastic pipe.
What should I do right now?
Stop using every drain, toilet, and water-using appliance in the house immediately, then find your sewer cleanout, a capped pipe usually near the foundation or at the property line.
Every flush or load of laundry you run pushes more water into an already-blocked line, which increases the chance it backs up into a tub, shower, or floor drain instead of staying contained. Turn off the washing machine if it is mid-cycle. Do not flush the toilet again until the blockage clears.
Next, locate the cleanout. It is typically a white or black PVC or cast-iron cap sticking a few inches out of the ground near the house, sometimes along the side yard or near the water meter. If sewage is backing up inside, carefully removing the cleanout cap outside relieves pressure and redirects the overflow away from your floors, since the blockage is almost always between the house and that point. Keep kids and pets away from the area; raw sewage carries bacteria and should not be handled without gloves.
If the backup is active and spreading, call a licensed plumber right away. Because All Pro Plumbing Heating and Air answers calls around the clock in Bakersfield, you do not have to wait for business hours to get someone dispatched for an active main-line backup.
Plumber or the City of Bakersfield: who fixes it?
In most California cities, including Bakersfield, the homeowner owns and maintains the sewer lateral running from the house to the connection at the city’s main line in the street; the city is generally responsible only for the main line itself.
That means if the blockage sits in your lateral, which is the far more common scenario for a single-home backup, it is a plumbing repair, not a city responsibility. If multiple homes on the same street are backing up at the same time, that points to a problem in the city’s main line instead, and the City of Bakersfield’s Public Works Department is the one to notify. A camera inspection is the fastest way to confirm which side of the property line the blockage sits on before you call either party.
Do not assume the city will clear a private lateral. Confirming this before a truck rolls out saves a wasted trip for either side.
How does a plumber find and clear the blockage?
A plumber clears a blocked main line with a drain cable or hydro-jetter fed through the cleanout, then confirms the pipe is fully open and sound with a sewer camera.
For root intrusion or grease buildup, a cable machine with a cutting head typically cuts through the blockage first to restore flow, after which a hydro-jetter, which uses high-pressure water, scours the pipe walls clean rather than just punching a hole through the clog. Once water is moving again, the technician runs a camera down the line to see the pipe’s actual condition: is this a simple maintenance clear, or is the pipe itself cracked, bellied, or collapsed somewhere along its run? That distinction determines whether you need periodic cleaning or an actual line repair.
For older clay or cast-iron laterals with structural damage, trenchless methods like pipe lining or pipe bursting repair the line without digging up the whole yard. Our guide to trenchless sewer repair covers how those two methods compare if the camera finds damage rather than a simple clog.
What causes sewer backups in Bakersfield homes?
The three most common causes locally are tree roots, grease buildup, and aging clay or cast-iron pipe nearing the end of its service life.
Bakersfield’s mature tree canopy, especially downtown and in older neighborhoods, means established root systems seek out any moisture source, and a hairline crack or joint gap in a clay sewer line is exactly that. Roots work their way in, then grow into a mat that catches paper and waste until the line backs up. Grease poured down kitchen sinks over years hardens inside the pipe and narrows the channel the same way plaque narrows an artery. And original clay and cast-iron laterals installed before 1970, common across Oleander, Westchester, and East Bakersfield, develop cracks, offset joints, and bellied sections simply from decades of soil movement and age, independent of what gets flushed.
Who handles the cleanup after the backup?
Water that comes from a sewer or drain backup is classified as Category 3, or black water, under the IICRC’s S500 water damage restoration standard, meaning it carries contamination that requires specialized cleanup, not just mopping and drying.
A plumber’s job is stopping the backup and fixing the line; drying out carpet, sanitizing affected walls and flooring, and handling any contaminated materials is a separate scope of work. Most standard homeowners policies do not automatically cover sewer backup damage; it usually requires a specific water backup, or sewer/sump, endorsement added to the policy, so check your declarations page before assuming a claim is covered.
This is where the One Call Does It All approach matters in practice: the same team that clears and repairs the line can coordinate with our sister company, ProRestoration Services, which handles the Category 3 drying and rebuild work if sewage spread beyond the fixture itself. You are not left finding a second contractor on an already bad day.
