Drain Cleaning near you

Cabling, also called snaking or rodding, drives a rotating steel cable down the line with a cutting head on the end. It punches through or chews up the blockage and restores flow, and for hair, a toy, or roots that have narrowed a pipe it is often all that is needed. It is quick and it is the usual first attempt, but it clears a channel rather than the full diameter of the pipe, which is why a line cabled every spring is frequently a line with an underlying defect.

Hydro jetting uses high-pressure water through a nozzle that pulls itself along the pipe, scouring the walls rather than boring a hole through the middle. It is the appropriate answer to a kitchen line glazed with grease and to a main line with heavy buildup, and the San Francisco Public Utilities Commission specifically describes clearing and jetting the lateral as the way property owners keep the pipe clear and in working order. Jetting is not right for every pipe: a plumber should know the material and condition before putting that kind of pressure into an old or already cracked line.

The camera is what turns a repeat clog into a diagnosis. A self-levelling camera pushed down the cleared line shows roots at a joint, a belly holding standing water, an offset where the pipe has separated, or a section that has collapsed, and it locates the trouble by distance and depth so it can be dug up at the right spot. SFPUC recommends closed-circuit television inspection to identify defects in the lateral. If a company has cleared your main line twice and never put a camera in it, ask why.

EPA's own list of what causes sewer overflows reads like a list of what causes household backups, because they are largely the same failures at different scales. Tree roots entering through defects or openings in a sewer line cause blockages. Fats, oils and grease, together with household products including some marked flushable, such as baby wipes, facial wipes, sanitary pads and tampons, are named by EPA as inappropriate materials to send to the sewer. Stormwater, groundwater and snowmelt entering the sanitary system through cracks, faults and leaky joints overload it, which is the mechanism behind a backup that only ever happens in a downpour.

Grease is the one that surprises people, because it goes down as a liquid and sets as a solid. It cools in the horizontal run, catches everything fibrous that follows it, and builds a restriction that no amount of hot water rinses away. Roots are the other slow failure: they do not break into a sound pipe, they find an existing crack or an open joint and then thicken inside it, which is why root intrusion tends to recur at exactly the same distance down the line year after year.

The pipe between your house and the public sewer is yours. The San Francisco Public Utilities Commission puts it plainly for property owners, describing the upper sewer lateral as an extension of your home even though you cannot see it, and saying you are fully responsible for it. Responsibility frequently extends beyond the property line, which is why a blockage under the sidewalk is still the owner's to clear. Municipal responsibility generally begins at the sewer main in the street, and EPA's guidance for homeowners who suspect the public system is to ask the municipality to investigate.

Backwater valves sit at the boundary between maintenance and code. Los Angeles County Public Works describes the device as designed to shut automatically to prevent sewage from an obstructed public sewer leaking out of a plumbing fixture, and says the protection is needed where the drain of the lowest plumbing fixture in the building sits lower than the upper manhole of the public sewer. The county also warns that root cleaning machines, debris and other problems can damage or interfere with a backwater valve, which is a real consideration when scheduling a cabling job in a house that has one.

Once the camera shows a broken, offset or root-filled section, the work stops being drain cleaning and becomes a repair, usually with a permit, an inspection, and in many places a requirement to have underground utilities located before anyone digs. Ask who pulls the permit, who schedules the inspection, and whether the quote covers restoring the yard, driveway or sidewalk afterward.
