Indianapolis homes and their plumbing
Here is how Indianapolis's homes break down by year built, based on Census estimates for the covered ZIP codes: before 1940 15%, 1940–1959 18%, 1960–1979 25%, 1980–1999 24%, 2000 or later 18%. 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 Indianapolis homes
Pre-1960 homes: galvanized pipe and cast iron
33% of homes in Indianapolis's covered ZIP codes were built before 1960, 15% 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.
Long, hard winters
58% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Indiana winter those are the lines that freeze and split. See frozen and burst pipe repair.
Natural gas in most homes
57% of occupied homes here heat with utility gas, so gas water heaters, ranges and dryers are common. That means gas line extensions for new appliances, flexible connector replacements and venting checks when a water heater is swapped. If you smell gas, leave first and call the gas utility from outside. See gas line repair.
Hard water
Indiana water is generally hard. With 41% of homes here on electric heat, scale on electric water heater elements is a frequent failure. See water softener installation.
