No. The water is not potable should not be used for drinking water.
Water passes through non-food-grade hosing (the blue and red water hosing), copper pipes (inside the HOTTAP that picks up heat from the heating element), and, in a short section, some plastic/ rubber.
While no dangerous materials have been used, we have not been tested to be safe for potable use. So, we cannot make that claim and do not recommend drinking water from your HOTTAP.
