Chattanooga homes and their plumbing
Here is how Chattanooga's homes break down by year built, based on Census estimates for the covered ZIP codes: before 1940 12%, 1940–1959 20%, 1960–1979 27%, 1980–1999 19%, 2000 or later 22%. With that many older homes, original galvanized supply pipe and cast iron or clay drains are still common, so leaks, rust and root intrusion come up often.

What goes wrong in Chattanooga homes
Pre-1960 homes: galvanized pipe and cast iron
33% of homes in Chattanooga's covered ZIP codes were built before 1960, 12% of them before 1940. Houses that old often still have galvanized steel supply lines that rust closed from the inside, and cast iron or clay sewer pipe that cracks and lets roots in. Weak pressure at upstairs fixtures, brown water after a shutoff and slow drains are the usual clues. Typical fixes are whole-house repiping and a sewer camera inspection.
Mostly electric homes
73% of occupied homes here heat with electricity, and electric tank water heaters are the norm. Failed elements and thermostats are repairable, but tanks that leak need replacement. Heat pump water heaters are an efficient replacement where there's space and airflow.
Winter freezes
59% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a cold Tennessee winter those are the lines that freeze and split. See frozen and burst pipe repair.
