56% of homes here predate 1960, when clay and cast iron sewer laterals were standard. Roots and cracks in those lines are a common cause of backups.

33% of occupied homes in Rush County heat mainly with wood or propane, above the Indiana county median of 17%.
Muggy summer nights, lows of 65°F or more, come about 36 times a year in Rush County. Mold after a leak spreads fastest from June through August.
Local risk profile
About 16,739 people live in Rush County, 408 square miles in eastern Indiana, in roughly 7,387 homes. Besides Rushville, the county seat, the biggest communities are Arlington, Carthage and Milroy. It has some of the oldest housing in the state: the median home went up in 1954.
64/100 Water Damage Risk Index: Elevated Rush County ranks 4 of 92 Indiana counties. See the statewide ranking and method.The three factors where Rush County ranks highest compared with other Indiana counties.
Pipe-freeze risk in Rush County sits near the middle of the state. From 2015–2024 it averaged 31 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 104 nights at or below 32°F. That ranks 51st of 92 counties.
The longest cold spell was straight 15 days without the temperature rising above freezing, ending in February 2021. The coldest night reached about -11°F on January 2, 2018. Burst pipes usually show up when a spell like that breaks and the ice thaws.
Expect the hardest freezes in January, inside a season that runs November to March. That's when an outdoor spigot left connected to a hose, or a pipe in a crawl space, is most likely to split.
Freezing nights typically start around Oct 26 and end around Apr 18.
Rainfall is about average for Indiana. About 8.8 days a year bring an inch or more (35th of 92), most often in July, out of 45.8 inches of total precipitation. On June 19, 2021, 2.85 inches fell in a single day. The worst three-day stretch dropped 4.26 inches, ending September 9, 2018, the kind of soaking that overwhelms sump pumps and storm sewers.
The temperature crosses 32°F in both directions on roughly 80 days a year. Each cycle melts and refreezes water at roof edges and in foundation cracks, which is how ice dams and basement seepage get started.
Housing
73% of homes in Rush County predate 1980, above the Indiana county median of 58.2%, which ranks 8th of Indiana's 92 counties.
56% were built before 1960. Homes from that era often still have galvanized steel supply pipe, which rusts from the inside until it pinholes, and cast iron drains that crack with age. Slow leaks behind walls are a common start to water damage in these houses.
Beyond water
Summer nights that don't drop below 65°F, a good marker of humid air, come about 36 times a year here, close to the Indiana county median of 38. Keep indoor humidity under 60%, as the EPA advises, and dry any leak within 24 to 48 hours; in a humid month a wet basement left alone won't dry by itself.
Mold remediation: what to expectHeating fuel matters for fire risk. In Rush County it's 39% utility gas, 25% electric, 29% propane and 4% wood. Wood and propane heat are more common here than the state median. Have chimneys swept and fuel-burning appliances serviced each fall, and keep three feet clear around stoves and space heaters.
