  • A high concentration of sulfate in the raw water
  • Sulfate reducing bacteria, non-toxic to humans (sulfate is reduced to a sulfide state by the bacteria)

Ways to get rid of smelly water.

The instructions are for cleaning your water heater with chlorine bleach (clorox).

Example – A 50 gallon water heater would require 250 ounces of bleach (about 2 gallons).
