Here is a list of what could have gone wrong with the water purifier.

  • The level of Total Dissolved Solids (TDS) might be increasing, slowly.
  • Bacteria film can also be introduced into the system if you change the filter without properly sanitising your hands.
  • Smells or tastes metallic from iron, arsenic, or mercury seeping in your water
  • Excess chlorine used by the municipal corporation may react in the purifier which makes the water smell bad.
  • As water moves through the ground, it absorbs hydrogen sulfide, which could be a cause of the foul smell.
