If your water smells like rotten eggs, the odor is usually caused by the levels of sulfur bacteria and Hydrogen Sulfide that can be found in a building’s water supply. If you smell when using your hot tap, it may be a chemical reaction occurring inside your hot water heater, and not a problem with your water supply.
f the sulfur odor occurs only in the hot water, the most likely source is a reaction between an anode rod in the water heater and natural sulfate ions in the water. An anode rod is made from magnesium or aluminum, and its purpose is to protect the steel water heater tank from corrosion. Magnesium rods are more likely to cause the odor, so the first step would be to replace the magnesium rod with an aluminum rod. If the aluminum rod still produces the odor, the next step would be either to operate the water heater without an anode rod or to remove the sulfate ions.
Removing the anode rod would remove its corrosion protection, potentially shortening the life of the water heater tank.
The most common odor complaint, "rotten egg smell", is derived from hydrogen sulfide gas dissolved in the water. Concentrations as little as 1 ppm can result in this odor. Most often "smelly water" will be noticed when a water heater has not been used for a long time allowing the accumulation of this hydrogen sulfide gas.
The smell is the result of four factors that must all be present for the odor to develop. These factors include:
With these factors the hydrogen and sulfur combine to form the hydrogen sulfide gas that gives off the rotten egg odor.
To get rid of this odor water structurer with our water filter with direct flushing of impurities that includes a nano silver 999.9% membrane cartridge.
