My Water Smells Like Rotten Eggs! - Solution

What causes my hot water to smell like rotten eggs? My cold water doesn't smell, what is the solution for this problem? The most common cause of "smelly water" is a non-toxic sulfate reducing bacteria, scientifically termed Divibrio Sulfurcans. This bacteria often enters the water system through construction or a break in ground piping. The bacteria creates the energy it needs to survive by converting sulfate (SO4) to hydrogen sulfide (H2S) gas you smell in the water. Hydrogen sulfide gas is distinctive because of its rotten egg-like stench. Its presence can severely affect the taste as well as the odor of the water. The simplest treatment available is the shock-chlorination of the system. This is a surface treatment, and often requires repeated trials in heavily infected systems. The chlorination of a system requires that you follow each step explicitly to avoid an un-treated portion of the piping system from reinfecting another part. Longer lasting solutions include chlorination or aeration of the water supply. Want to learn more about plumbing?
