Sewer line problems in older homes: what to expect and how to address them.
Homes built before 1980 in Metro Atlanta and North Georgia carry sewer line risk that newer construction does not. The pipe materials used in earlier eras deteriorate with age, and most of these pipes have never been camera inspected. Understanding what is likely in the ground at your property — and what to do about it — is basic homeownership for older homes.
Pre-1960s homes: clay tile sewer laterals
Clay tile pipe was the standard sewer material through the mid-20th century. Clay is chemically stable and does not corrode, but clay tile sewer systems use gasketed joints — rubber or oakum-packed connections between sections — that are the most common point of failure. Roots enter through the joints. Ground settling causes joints to shift and offset. Age causes gaskets to deteriorate.
Clay tile in good condition can last well past 60 years. Clay tile with significant root intrusion, joint failure, or offset sections may be at or near end of life. Camera inspection is the only way to know which you have.
1960s–1970s homes: cast iron and transition era
Cast iron pipe was standard for drain and sewer lines in 1960s–1970s construction. Cast iron is durable but corrodes internally over time from hydrogen sulfide exposure. The degree of corrosion varies significantly depending on local sewer gas conditions, soil type, and whether any chemical cleaners or high-acid waste have gone through the line. Camera inspection shows the interior condition; external appearance tells you nothing about what the inside looks like.
1945–1972 homes: Orangeburg pipe risk
Orangeburg — a paper-and-pitch composite material used widely during and after World War II — was designed for a 50-year lifespan. Most Orangeburg is now 50–80 years old and is failing or has already failed. It absorbs moisture, softens, deforms, and collapses. If your home was built between 1945 and 1972 and the sewer line has never been camera inspected, the presence of Orangeburg is a real possibility. It is not jettable in deteriorated condition — it needs replacement.
What to do for an older home
Start with a camera inspection. The footage shows you exactly what pipe material is in the ground and its current condition. If the pipe is in good condition, you know that and can plan appropriate maintenance intervals. If it shows problems — significant corrosion, root intrusion, Orangeburg, or structural failure — you have the information to plan repair or replacement before an emergency forces the decision.
