Indoor community installations


Maintenance and good use


It is important to identify where the responsibilities of the water service and municipal sewer system end and the obligations of owners begin. This is why it is essential to know what elements of the drinking water installations and sewer system are considered public and which are part of the building receiving the service.

The correct use and maintenance of indoor installations is the responsibility of the owners, whether they are private individuals, companies or residents’ associations.

Indoor installations requiring sanitary and hygiene maintenance are:

  • Aerators on taps

    These should be removed and cleaned at least once a month. Submerging them in a mild acid solution, such as vinegar or citric acid solution, for a few hours and then rinsing with tap water should be enough.
  • Water softeners

    UAdequate maintenance of this equipment should include readjusting regeneration cycles (or, even better, volumes) to match the required reduction in hardness.
    After regeneration, it is important to check that washing is carried out properly, ensuring no excess salt remains in the filter.
  • Reverse osmosis

    Preventative maintenance recommended by installers includes replacing filters and membranes regularly (once or twice a year).
  • Tanks
