Rotten Egg or Sulfur Smell from Faucet

A musty or earthy faucet smell is usually caused by the presence of algae, mold, or bacteria in the water supply. Algae can thrive in water sources that are exposed to sunlight or that are high in organic matter, such as lakes or reservoirs.

  2. Ultraviolet Sterilizing: Installing an ultraviolet sterilizing system can effectively kill bacteria and algae in water, reduce or eliminate musty smell. UV disinfection systems are effective in reducing microbial contaminants in water and can help eliminate musty odors caused by certain bacteria or algae.

  2. Install a Reverse Osmosis System: The solution to removing metallic taste from drinking water is to install a reverse osmosis (RO) system, a highly efficient water filtration method used to remove various impurities from water, including metallic taste. Pre-filtered water is forced under pressure through a semi-permeable membrane. The membrane has tiny pores that allow water molecules to pass through while blocking larger molecules and impurities. Metal ions, along with other dissolved solids and contaminants that cause a metallic taste, are effectively filtered out by RO membranes.
