Sediment Buildup

Leaking Tank
Corrosion from age or high water pressure can cause leaks. A leaking tank often requires immediate replacement to prevent water damage.
Pilot Light or Ignition Failure
Gas units may have issues with the pilot light or thermocouple, leading to no hot water. This can sometimes be repaired, but replacement is common for older systems.
