My hot water has a strong sulfur smell and has a shade of black. Whats wrong?
This is caused by the anode rod in the heater reacting to certain differences in the water. The anode rod is magnesium and is in the heater to protect it from corrosion, when this problem occurs an aluminum rod could be used as a replacement, it is not as effective as magnesium but is less likely to cause a sulfur odor. In some cases this still won’t work. Then the only solution is to remove the rod completely. This may shorten the life of the tank but it is still better than having a sulfur odor.
