On a main sewer line, we take one extra step that matters in this city. We look inside the lateral before we cut into anything hard.
Drain backing up? Request drain cleaning from Works Plumbing.
| Location | Common causes | Usual approach |
|---|---|---|
| Kitchen sink | Grease, food scraps, disposal waste | Clear the trap and branch line, flush |
| Bathroom sink | Hair, soap, toothpaste residue | Pull and clean the stopper and trap, snake the branch |
| Tub and shower | Hair and soap | Snake through the drain or overflow |
| Toilet | Wipes, paper, foreign objects | Toilet auger, then check the line beyond |
| Laundry | Lint and fabric fibers | Clear the standpipe and branch |
| Main line or lateral | Roots, grease, debris, sags, breaks | Camera, then cable or water jetting |
When those signs show up, the problem is downstream of the individual fixtures, and clearing one sink will not fix it.
Palo Alto’s Rule 23 splits the sewer lateral. Where an accessible City Sewer Cleanout exists, usually in the planting strip, the City owns the section from the main up to and including that cleanout. The owner is responsible for the section from the cleanout to the house.
When we clear a main line, we note where the blockage sits. If it is in the City’s section, we tell you, so the City can clear its portion. Rule 23 also gives City and utility personnel the right to access the entire lateral for the cross bore inspection program, so a crew may already have filmed yours.
Kitchen drains clog differently from bathroom drains. Grease, oil, and fine food solids cool and stick to the pipe wall, and the opening narrows until a heavy holiday meal or a full dishwasher finishes the job.
A cable punches a hole through that buildup, and the drain runs again. But the coating on the walls is still there. For a kitchen branch that clogs repeatedly, we clear it and then recommend jetting if the buildup is heavy, so the pipe is cleaned back to its full size.
Fixtures at the lowest level of a house are the first to show a main line problem. A basement shower, a ground-floor bathroom, or a laundry floor drain will back up before anything upstairs does.
If your lowest drains are the ones backing up, we start at the main cleanout rather than at the fixture. We also check whether a backwater valve protects those fixtures and whether it is working.
Some clogs come back because the pipe itself has a problem. A belly that holds water, an offset joint, or a crack that lets roots in will keep catching debris.
For heavy grease or root buildup, hydro jetting in Palo Alto scours the pipe wall instead of punching a hole through the blockage. When the pipe is damaged, our camera footage shows where, and we price repair options so you can decide.

What is a cross bore, and could my home have one?
A cross bore is a gas line accidentally bored through a sewer lateral during installation. The City of Palo Alto Utilities is inspecting laterals citywide to find them, and says a crossbore must be repaired immediately. We camera hard lateral blockages before cutting for that reason.
The City inspected my lateral for cross bores. Does that mean it is clear?
The City’s inspection looks for gas lines inside the sewer lateral. It is not a drain cleaning service. Roots, grease, and sags can still cause clogs, and we can review any footage you have.
Who clears a sewer backup in Palo Alto, me or the City?
It depends on where the blockage is. Under Rule 23, the City clears its section of the lateral, and the owner is responsible for stoppages in the private section. We locate the blockage and tell you which side it is on.
Why do my drains keep clogging after cleaning?
Repeated clogs usually mean a pipe problem such as roots, a sag, or an offset joint. A camera inspection shows the cause so the fix addresses it rather than the symptom.
What should I do if sewage backs up into my house?
Stop running water in the house so the backup does not get worse. Keep people away from the affected area and call us. If the backup is in the City’s section, the City of Palo Alto Utilities clears it.
Do you use chemical drain cleaners?
We clear drains mechanically with augers, cables, and water jetting. That removes the blockage instead of leaving chemicals sitting in the pipe.
A slow drain is easier to fix than a backup. Contact Works Plumbing for drain cleaning with upfront pricing and a clear explanation of what we found.
The most common residential plumbing problem in the San Francisco & Peninsula area is a clogged drain. Fortunately, most clogs occur in the trap. In fact, that’s the trap (also known as the p-trap) is supposed to do. It gives your household drains a place to collect debris in a location that’s easily accessed and cleaned. On rare occasions, sink stoppers can get shift due to pressure, and pipes under the sink or in a wall can clog or leak.
Every job comes with upfront pricing, licensed and background-checked technicians, and a 100% satisfaction guarantee . No surprises, no pressure, ever.
Snap a photo of the problem before you call, it helps us bring the right parts on the first visit.

A look at real Works jobs around the Peninsula.
A cross bore is a gas line that was accidentally bored through a sewer lateral when the gas line was installed. The gas pipe sits inside the sewer pipe, and nobody knows it is there until something hits it.
The City of Palo Alto Utilities is looking for them. Its Crossbore Phase IV-A program inspects private and public sewer laterals citywide “to verify natural gas pipelines were not installed within the sanitary sewer lateral service.” The phase covers 963 laterals, began in September 2024, and uses City crews with camera inspection. The City’s position is clear: a crossbore “must be repaired immediately.”
Why should a drain cleaner care? A clogged lateral with a gas line through it often looks like a stubborn root or debris blockage. A cutting head spun hard into that obstruction could damage the gas line inside the sewer pipe.
So on lateral work, we do not start by forcing a cutter through a blockage we cannot see. We run a camera first when the clog is hard, recurring, or in a section that has never been filmed. If the footage shows anything that looks like a pipe crossing the lateral, we stop, keep the area safe, and contact the City of Palo Alto Utilities.
Most of the time the camera shows roots, grease, or a sag. Then we choose the right tool for what is actually there.
