Common water heater problems in Gantt homes
Sediment buildup from hard water
Gantt's water supply can cause sediment accumulation, reducing efficiency and lifespan. Regular flushing helps, but replacement may be needed for older units.
Corrosion in older tanks
Homes built in the 1970s often have aging water heaters prone to rust. A leaking tank requires immediate replacement to prevent water damage.
Inadequate capacity for household size
Many older homes have 40-gallon tanks that may not meet modern usage. Upgrading to a larger or tankless unit can resolve frequent cold showers.
