Common Water Heater Issues in Maryville
Sediment Buildup
Hard water minerals accumulate in the tank, reducing efficiency and causing rumbling noises. Flushing annually helps, but older units may need replacement.
Leaking Tank
Corrosion from age (typical lifespan 10–15 years) leads to leaks. A leaking tank often requires immediate replacement to prevent water damage.
Pilot Light or Ignition Failure
Gas units may have faulty thermocouples or gas valves. If repairs are costly, replacement is more practical.
