If you’re dealing with persistent leaks, discoloration, or noises from your water heater, you might want to consider a local plumber to ensure the job is done safely and correctly.

Can I Hire an Electrician to Fix a Water Heater?

Electricians are a good fit when the problem lies with the electrical system, especially on electric water heaters that have internal breakers and more electrical components. Gas water heaters can also have electrical issues an electrician can address. If you are not seeing discoloration, leaks, or noises but the unit will not work, call an electrician.

How Do Plumbers Fix Water Heaters?

Plumbers follow a clear diagnostic process and repair what is needed; a leaking tank usually requires replacement. They also consider unit age when advising repair versus replacement. Steps include:

1. Inspect the unit and confirm symptoms.

2. Check anode rod, thermostat, thermocouple, gas valve.

3. Test water—determine if a flush is needed.

4. Diagnose leaks and assess tank integrity.

5. Present findings and recommend a solution.

6. Advise replacement if repairs become frequent.

7. Complete repair or schedule replacement.

8. Verify safe, correct operation before finishing.

How Much Does Fixing a Water Heater Cost?

Expect plumbers to charge $45 to $200 per hour and electricians $50 to $100 per hour, with emergency plumber rates 1.5 to 3 times higher. Repairing a tank-style unit costs $225 to $990, while replacing a water heater runs $880 to $1,810. Repairing a tankless unit costs $75 to $1,300, with replacement at $1,400 to $3,900. Price depends on the repair needed, heater type, and the pro’s experience; some maintenance, like a water heater flush, averages $160. Costs ultimately depend on diagnosis and scope of work.
