What goes wrong in Marion homes
Pre-1960 homes: galvanized pipe and cast iron
46% of homes in Marion's covered ZIP codes were built before 1960, 28% 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
66% 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.
Long, hard winters
75% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Ohio winter those are the lines that freeze and split. See frozen and burst pipe repair.
1960s and 70s homes reaching end of life
29% 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.
