Orangeburg is a bituminous fiber pipe used in sewer laterals mainly in the mid-twentieth century. It softens, blisters, and deforms over time, which usually rules out lining. Pipe bursting is typically the trenchless way to replace it with new HDPE. In Mar Vista, Orangeburg is less common than clay, but we do find it in some postwar homes and older partial repairs.
Orangeburg pipe is made from layers of wood-pulp fiber bonded with coal-tar pitch. It was inexpensive and easy to install, which made it popular in the mid-twentieth century. The problem is that it doesn't stay round. Over time it absorbs moisture, softens, blisters on the inside, and flattens under the weight of the soil above it. This page is part of our complete guide to trenchless sewer repair in Mar Vista.
Orangeburg Pipe Replacement: Orangeburg is a mid-century bituminous fiber sewer pipe that deforms with age; replacement, often by pipe bursting, is the standard fix.
That's why lining is rarely the answer. A liner needs a round host pipe, and deformed Orangeburg can't give it one. Pipe bursting works because it doesn't need the old pipe to hold its shape; it breaks the old line apart and pulls new HDPE into the same path.
In Mar Vista, Orangeburg is less common than clay, but we do find it in some postwar homes and older partial repairs. Mar Vista's postwar building boom overlapped with Orangeburg's popularity, so some homes have it.
The camera identifies Orangeburg by its blistering and oval shape.
We locate the line and nearby utilities to plan the bursting path.
The bursting head breaks up the fiber pipe while new HDPE follows.
A final camera pass and inspection close out the job.
Camera first, always. Every recommendation starts with a recorded inspection you can watch yourself, and a flat-rate price you approve before we start.
Most Mar Vista laterals are clay, but Orangeburg does turn up here, usually in some postwar homes or as an old partial repair spliced into a clay line. That second case is easy to miss without a camera: a short fiber section in the middle of a clay run can flatten and cause backups even when the clay on either side is serviceable. When we find it, we plan around it. Sometimes the whole lateral gets burst and replaced; sometimes we replace the Orangeburg stretch and line the clay. We show you exactly where it is on the footage before recommending anything.
Most Mar Vista homes went up between the 1920s and the 1950s, and a lot of them still drain through the sewer lateral they were built with. Many laterals here have been patched once or twice over the years, so a single run can mix clay, cast iron, and newer plastic. Because we're based on Charnock Road, a Mar Vista call is a short drive for our trucks, not a cross-town dispatch.

Mar Vista is inside the City of Los Angeles, so sewer work on private property is permitted and inspected through LADBS. The inspector checks the new pipe, the connections, and any cleanout before the job is closed out, which is the record you want at resale. We'll tell you up front if your job needs anything beyond a standard plumbing permit.
Example scenario below is illustrative, based on common situations we see. Details vary by property; not a specific customer.
A Mar Vista homeowner has backups the previous plumber blamed on roots, but cleaning doesn't help.
Our camera finds a flattened Orangeburg section spliced into the clay lateral from an old repair.
We burst and replace the full lateral with HDPE, removing both the Orangeburg and the aging clay in one job.
New Pro Plumbing is family-owned and led by Miguel Lopez, and many Mar Vista customers ask for him by name. Our trucks carry the camera, locating, jetting, and repair equipment most sewer jobs need. We protect floors, walkways, and landscaping while we work, then clean up completely.

The Bottom Line
Orangeburg doesn't get better with age, and it usually can't be lined. Bursting replaces it along the same route with new HDPE through small access pits.
A camera inspection shows it clearly: the pipe often looks oval or flattened, with blisters on the inside surface. The home’s build date is a clue, but only the camera confirms it. Orangeburg is a bitumen-impregnated wood-fiber pipe from roughly 1945 to 1972. It softens and deforms rather than cracking cleanly, and it does not hold a liner. Our Orangeburg pipe replacement page covers it in detail.
Rarely. Lining needs a round host pipe, and Orangeburg tends to deform. Bursting and replacement is usually the reliable fix. Because Orangeburg loses its round shape, lining is rarely an option. Pipe bursting is the standard fix; the burst head fractures the old material as it passes and pulls new HDPE into the same corridor.
It isn’t hazardous to touch, but it’s prone to collapse, which can cause backups and sewage damage. It’s worth replacing before that happens. Orangeburg is not obvious from the surface, and homes of the same era sometimes have clay or cast iron instead. Only a camera can confirm the material, which is why we camera before quoting.
Carefully, if needed to restore flow temporarily. Aggressive cleaning can damage it further, which is another reason replacement is the long-term answer. In LA, most Orangeburg we find is in postwar tract housing on modest lots. When it turns up, we usually recommend full replacement rather than repeating spot repairs that don’t hold.
Only a camera confirms it. In Mar Vista, it turns up in some postwar homes and sometimes as an old repair section spliced into a clay line. Orangeburg is a postwar material and appears in Mar Vista mostly in tract housing from the 1945-1972 window. Only a camera confirms it.
