What shapes water heater trouble in Franklin
Hard aquifer water
Franklin pumps its water from five wells in the Great Miami Valley Buried Aquifer and runs it through a 5 million gallon a day plant with iron and manganese filtration. The Water Division gives the hardness as 22 grains per gallon for customers setting water softeners. The city has backup connections with Springboro and Warren County.
Hard water leaves scale in a tank and on electric elements, so flushing the tank and checking the anode matter more here. Water questions go to Public Works at (937) 746-5001.
Inventory at Public Works
In the city's most recent sampling, none of 30 homes was over the lead action level, and the 90th percentile result was 2.10 ppb. The service line inventory can be viewed at the Public Works building, 202 Baxter Drive. The city has mailed letters to homes with lead, galvanized or unspecified lines and held town hall meetings about them.
1960s homes, gas and electric
The median Franklin home was built in 1967, about 19% are older than 1940, and about 15% date from 2000 or later. About 74% are detached houses and about 39% of households rent. Gas heats about 63% of homes and electricity about 34%, so both kinds of water heater are common. The city lists Duke Energy for electricity and for gas problems.
