In order to be able to narrow down the problem, it is first of all important to carry out an exact analysis:

  • What exactly does the tap water smell like? (putrid, rotten eggs, metallic...)
  • Where does it smell like? (at all sampling points, only at individual sampling points?)

Metallic smell

Metallic odor very often indicates iron oxide in the water. This can be determined by a water test. The cause often lies in the pipes themselves.

Above all, old, galvanized iron pipes lose their zinc coating after a few years and release iron compounds into the water, especially if the water is longer in the pipes.

Foul smell

Decaying organisms in the field of water installation are extremely rare, so the cause is almost impossible.

Foul odors are often caused by swirling of waste water gases and odors, which can pass into the pipes of the fresh water in certain areas. Here, the installation must be checked carefully.
