What shapes water heater trouble in New Carlisle
Deep wells in a glacial valley
The city's water report says New Carlisle's water comes from deep wells in sand and gravel deposits that fill a glacier-scoured valley. The wellfield sits north and east of the Water Treatment Plant at 434 N. Main Street. Ohio EPA rates the aquifer highly susceptible to contamination; compliance samples since 1993 have found nitrate above 2 mg/L on 17 occasions, between 2.13 and 4.6 mg/L, all under the 10 mg/L limit.
The report says neither lead nor copper exceeded the action level in the latest round and lists no violations. To find out what your service line is made of, call the Utility Clerk at (937) 845-9492. The water plant superintendent is at 937-845-3059.
Gas heat in 1960s houses
Census estimates put the median New Carlisle home at 1966, with about 31% built before 1960 and about 9% since 2000. About 80% are detached houses and about 33% of households rent. Gas heats about 85% of homes and electricity about 12%, so most tanks here are gas.
If a gas tank's pilot won't stay lit or the burner won't come on, the thermocouple or gas valve is a common culprit. If you smell gas, don't relight anything; leave and call from outside.
