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. The waste line in this case was found to be blocked, damaged, old,
and needing replacement in the course of an attempt to clear a blocked drain between the house and septic tank.

Diagnosing the Cause of a Blocked Building Drain or Sewer Line
The first signs of a drain problem
How to diagnose slow drains & toilet backups: The first signs of a drain problem was the report by our tenant that the toilet was
slow to flush in the home.
Is the slow drainproblem at a fixture, the whole building, or main drain? Following our own advice on diagnosing clogged drains
and how to distinguish a clogged drain from a failed septic system (online at Diagnosing Clogged Drains & Septic System Backups we asked if all the drains in the home were slow or just the toilet. The answer: all of the drains were
slow.
The toilet would show the most dramatic blockage because it sends a large sudden discharge volume of water
and waste into the sewer line. We flushed the toilet and watched the water rise right up to the bowl brim.
(If the toilet had begun to overflow we'd have reached inside the tank to manually close the tank flapper valve
to stop the flush.)
Though not optimistic that it would make any difference, we tried plunging the toilet aggressively with a
manual toilet plunger. It didn't help. Plunging the toilet made no difference. We already suspected a main drain or system problem
(all drains were slow). So we needed a plumber to help with further diagnosis of the drain blockage. [Continue this article using the links shown below.]
