Rusty Water from Taps — Water Heater or Pipe Corrosion

Rusty or discoloured water from hot taps indicates water heater or pipe corrosion. BC homeowners should investigate the source promptly.

Possible Causes

  • Corroding anode rod in water heater releasing sediment
  • Rusting interior of water heater tank approaching failure
  • Corroded galvanized steel pipes in older plumbing
  • Iron or manganese in well water supply
  • Sediment disturbance in water heater from recent maintenance

Recommended Steps

  • 1Check if discolouration is from hot water only (heater issue) or all taps (pipe issue)
  • 2If hot only, check water heater anode rod — replace if depleted
  • 3If all taps, corrosion is in the building piping — call plumber
  • 4Flush water heater annually to remove sediment
  • 5If water is brown or has metallic taste, call for pipe assessment
