Sewer Line Replacement Procedure - Installing the New Sewer Line
|
This article describes how the new sewer line is installed when a sewer pipe or "drain line" is replaced. We present an actual case study, illustrated with photos of each step in the diagnosis and replacement of a blocked sewer line. Technical reviewers are welcome and are listed at "References." This is a chapter of Inspecting, Testing, & Maintaining Residential Septic Systems an online book on septic systems. Also see Backups and Clogged Drains diagnosing septic backups and septic system failures versus clogged drains.

This avoided the cost and trouble of having to break through the foundation wall to install a new line into the home, and avoided possible damage to the nearby heating boiler. |
