A typical water heater repair takes 1 to 3 hours from arrival to completion. Simple repairs (thermocouple, T&P valve, supply line) finish in an hour. More involved repairs (gas valve, heating element, multiple-component diagnoses) run 2 to 3 hours. Replacement of the tank itself is a half-day to full-day job.
Typical timing
- Thermocouple — 45–60 minutes
- Gas valve — 90–120 minutes
- Heating element — 60–90 minutes
- T&P relief valve — 45–60 minutes
- Full tank replacement — 4–6 hours
- Tankless install — 6–10 hours
