Signs You Need Water Heater Repair
No Hot Water
Complete loss of hot water usually indicates a failed heating element, gas valve issue, or pilot light problem.
Lukewarm Water Only
If your water doesn't get hot enough, you may have a failing element, a broken dip tube, or sediment buildup in the tank.
Rusty or Discolored Water
Rusty hot water often indicates corrosion inside the tank. This may be repairable with an anode rod replacement if caught early.
Strange Popping or Rumbling Noises
These sounds typically come from sediment buildup at the bottom of the tank being heated. A flush can often resolve this.
Water Leaking from Tank
Leaks from the tank itself usually mean the inner lining has failed and replacement is needed. Leaks from connections or valves can often be repaired.
