Failing Orangeburg Sewer Lateral Replacement in Preston ID

A lot of older homes in Preston are still running on Orangeburg pipe - a compressed paper and tar material that was widely used for sewer laterals decades ago. It was cheap and it worked at the time. But it doesn't last. Over the years it softens, deforms, and eventually collapses, leaving you with slow drains, backups, or worse.

The fix isn't a patch job. Once Orangeburg starts failing, the only real solution is to trace the line from where it exits the house all the way out to the sewer main at the road - and replace the whole thing with proper pipe. That's exactly what we did here.

We cut through the concrete, opened up the trench the full length of the lateral, and pulled out the old deteriorated material. In its place, we ran new non-pressure PVC sewer pipe, set to the correct grade the entire run. Slope matters more than most people realize on a gravity sewer line - too flat and you get buildup, too steep and the water races ahead of the solids. We check it carefully every time.

If your home was built before the 1970s and you've been dealing with recurring slow drains or backups, there's a good chance Orangeburg is involved. A lot of homeowners in older parts of Preston are in the same situation. It's not something to keep snaking and ignoring - eventually it fails completely, and that's a much bigger headache than a planned replacement.
