Using the trash or compost instead of the drain is one of the simplest ways to prevent costly plumbing clogs.
Orangeburg pipe is a sewer pipe made from compressed wood fiber and tar, commonly installed in homes from the 1930s through the early 1970s. It was used because it was lightweight and inexpensive, but it degrades over time. Many older homes still have Orangeburg pipe underground, where it can soften, deform, and eventually fail.
