What shapes water heater trouble in Marion
Aqua water from rivers and wells
Aqua Ohio runs Marion's water system. Its 2025 report lists three sources: the Little Scioto River, the Scioto River and 18 wells. The water is disinfected with chloramines. The report doesn't list a hardness figure, so call Aqua at 877.987.2782 if you want one before buying a softener.
Aqua flushes Marion's mains, as it did in April 2026, and warns that the water can turn discolored for a while. It advises skipping laundry during flushing and running cold taps until the water clears. If your cold water clears but your hot water stays cloudy or brown, sediment may have settled in the tank, and a flush can help.
Old mains, lead and galvanized lines
Aqua says it is identifying and replacing all lead and galvanized service lines in its systems at no direct cost to customers, and its online map shows what its records list for your address. Its 2024 project on Mount Vernon Avenue was set to replace 5,900 feet of 120-year-old cast iron main. In 2023 lead testing, none of 30 samples was over the action level.
Old houses and many renters
The median Marion home was built in 1954, about 38% date from 1939 or earlier, and only about 6% were built in 2000 or later. In houses that old, the water heater may sit beside decades-old gas piping, venting and shutoff valves, and a replacement is a good time to have those checked. About 43% of households rent, so renters should tell the landlord first. About 77% of homes heat with gas, and Columbia Gas has run pipeline replacement work in parts of the city.
County plumbing permits, special pickup
Marion Public Health's plumbing program inspects new and renovated plumbing in Marion County and registers the state-licensed plumbers who work there. It contracts with the Delaware General Health District for plumbing services and offers a homeowner affidavit for owners who do their own install. Plumbing questions go to 740-387-6520.
