Five potential sewer line problems

The following information will give you insight on the flaws that can occur in a sewer line. A simple sewer scan is all that is needed to ensure your new home is free and clear of these problems.

Tree Root Invasion

A tree root system invades a home sewer line because of the moisture that resides in it. A root grows one cell at a time so it doesn't take much of an opening for it to penetrate the sewer line. Once inside, the roots will spread along the walls creating a blockage area for the home's sewage to collect.

Water Infiltration

Homes that were built before the 1970s primarily used clay tile as the "material of choice" for sewers. The pipe, laid in three foot sections, were shoved together without the use of a sealant. Over time, shifting of the ground can loosen sections to let in unwanted ground water. This type of problem can compromise a city's sanitary sewer system in times of rain.

Joint Separation

Joint separation occurs when the ground shifts so much that it creates an open space between the pipe sections. Sewage can now seep into the ground, creating an unhealthy situation. This pocket also is conducive for "things" to catch onto it - which could lead to a back-up.

Cracked Sections

Cracked sections are mostly seen in older clay tile systems. This problem occurs when the shifting of the ground puts too much strain on the pipe. Over time, this crack can separate from the pipe leading to a partial collapse of the line. Newly constructed homes have been known to have cracked or crushed lines due to heavy construction equipment.

Negative Sloping

Negative sloping occurs in old - and in some cases newer - sewer lines. This problem exists when the force of the ground up-heaves a portion of the pipe. This line now has a section of pipe with a pool of standing water. This problem has the potential for sewage to collect (not run-off) and create a back-up.
