This article describes when, where, how, and why a sewer pipe or "drain line" is replaced. The line which was replaced in this photo-illustrated case runs from the building exterior to a septic tank located downhill from the home. We present an actual case study, illustrated with photos of each step in the diagnosis and replacement of a blocked sewer line. 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.

Making Other Septic Repairs During Sewer Line Replacement

Later discoveries during excavation made us glad we'd decided to replace the entire drain line.

Not only was the sewer pipe broken in several other places, also we found and were able to repair a problematic leak at the entry of the drain pipe to the septic tank.

We found that the connection of the waste line to the septic tank had been leaking ground water into the septic tank in wet weather.

The nature of this into-septic tank leak problem was quite evident when it rained during our project as water ponded at the entry to the tank.

We confirmed that the tank had been flooded by opening the tank inspection cover at the intake baffle where we saw that sewage had flowed over the baffle top.

(Flooding a septic tank can result in early clogging and failure of the drain field.)

The "fix" in this case was a simple and expedient if crude concrete "seal" at the pipe entry to the septic tank to reduce the chances of water collecting and entering the tank at that point again.
