If the filters have not been cleaned and primed properly or if your tanks have not been thoroughly cleaned and rinsed, the water from your first filtrations may have a peculiar, even mineral taste. You can empty the first 2 or 3 filtrations.

If this persists, make sure that the black seals of the Black Berkey® filters are well positioned on the upper tank side and not above the butterfly nuts on the lower tank side.

If necessary, proceed again to a more rigorous cleaning and priming of your system.
