Flint homes and their plumbing

Here is how Flint's homes break down by year built, based on Census estimates for the covered ZIP codes: before 1940 18%, 1940–1959 35%, 1960–1979 32%, 1980–1999 10%, 2000 or later 5%. 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 Flint homes

Pre-1960 homes: galvanized pipe and cast iron

53% of homes in Flint's covered ZIP codes were built before 1960, 18% 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.

Natural gas in most homes

83% 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.

1960s and 70s homes reaching end of life

32% of the housing here dates from 1960 to 1979. Original copper supply lines in those homes are now 45 to 65 years old, and cast iron drains of that age scale up inside and crack. Seized shutoff valves, pinhole leaks and recurring main-line clogs are common calls. A camera inspection shows the condition of the sewer line before anyone digs.

Long, hard winters

85% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Michigan winter those are the lines that freeze and split. See frozen and burst pipe repair.
