Water heater: repair or replace?
Compare a service repair with replacement using tank condition, leak location, fuel and venting safety, capacity and operating-cost assumptions.
What supports replacement?
- The storage tank itself is leaking
- Fuel, venting or capacity changes require a new design
- Repeated failures and operating cost support a documented replacement case
Urgent signals
- Tank or connection leak near electricity or fuel
- Combustion, venting or carbon-monoxide concern
- Scalding, pressure-relief or structural support concern
