Leaking Tank or Connections
Corrosion from age (46-year-old homes) or loose fittings can cause leaks, requiring repair or replacement.
Sediment Buildup
Hard water sediment accumulates over time, reducing efficiency and causing noisy operation; flushing may be needed.
What to Expect During a Repair
A technician will first perform a diagnostic check ($85–$225) to identify the issue. For gas units, they'll inspect the burner and thermocouple; for electric, elements and thermostats. Repairs typically take 1–3 hours. If a permit is needed, the contractor will handle it. Seismic strapping and expansion tank compliance are checked. After repair, the system is tested for leaks and proper temperature.
