Enter the year your home was built and see which sewer and water line materials it most likely has, and how far along their service life they are.
This is a guide by era, not an inspection. Only a camera run shows what is actually underground.
Builders used what was standard in their day. Clay and cast iron came first, then Orangeburg fiber pipe in the postwar years until 1972, cast iron drains until about 1975, and PVC and ABS plastic after that. On the water side, galvanized steel gave way to copper by 1960, polybutylene ran from 1978 to 1995, and PEX took over after 2000.
Our central Arkansas places differ a lot in age. Little Rock has about 53 percent of its homes from before 1980, with a median year of 1978, and North Little Rock has about 59 percent and 1975. Conway is at about 20 percent and 1997, and Austin at under 9 percent and 2007. The checker starts from the median year for the place you pick.
Clay joints let roots in. Cast iron rusts from the inside until the bottom of the pipe channels through. Orangeburg softens and goes oval. Polybutylene lets go at its fittings without warning. The checker sets the age of your home against the typical service life of each material, so you can see which ones are near the end.
The era of the home sets the base score. Large trees near a jointed line add to it, and so do symptoms such as slow drains at several fixtures, gurgling, a backup or a soggy yard. The risk class combines all of them.
A low result means nothing here points at the line right now. An elevated or high result means a camera inspection is worth booking. It does not mean the line has failed.
A plumber runs a camera from the cleanout through the line and records the material, the joints, any low spots, roots or breaks, and the distance to each. That video is what turns a full replacement question into a spot repair question, or clears the line entirely.
Orangeburg is sewer pipe made of wood fiber pressed with tar, sold from about 1945 to 1972. It softens with age, flattens into an oval and lets roots in. Homes built in that window are the ones to check, and only a camera inspection confirms it.
Polybutylene is the gray plastic supply pipe installed from 1978 to 1995. It degrades on contact with treated water and tends to fail at fittings with no warning. A home from that window deserves a look by a plumber even without a leak.
About 50 to 60 years by the usual life-expectancy charts. Cast iron installed before 1975 is at or past that now. It fails from the inside, so the pipe can look sound while the bottom has rusted through.
The pipe material and size, the route to the street or septic tank, low spots that hold water, offset or broken joints, root intrusion, scale, and the distance from the cleanout to any problem. The plumber can show you the recording.
Roots follow moisture and find their way into joints on clay, cast iron and Orangeburg lines, then thicken until they block or split the pipe. Glued plastic joints keep roots out, though a large root can still crush a shallow line.
No. An old line can often be cleared, repaired in one spot or lined and go on working. The camera run tells you whether one joint has gone bad or the whole length has.
