De svarta partiklarna verkar vara från ett aktivt kolfilter som förmodligen misslyckas. Kontrollera ditt hus för en av filterhusen för att se om ett av dessa filter är närvarande.
Om det är aktivt kolpartiklar, sägs det att de är giftfria och livsmedelssäkra enligt Brita-webbplatsen. Eftersom du bara ser det på köksflänsen, kan filtret vara placerat under diskbänken.

Frågor om produkter och vatten filtrering
There are black particles in my water after filtering - what are
these?
The black particles are parts of one of BRITA's filter media, the
activated carbon. The granulated activated carbon is made of coconut
shells. Like each natural product, coconut shells are subject to
natural variances regarding product quality. This can lead to abrasion
of parts of the carbon into your filtered water. To eradicate any
carbon dust which may be present, preparation of your cartridge is
crucial. Please prepare as per your cartridge instructions or see
"How to prepare your cartridge". Please be assured that the contents
of the cartridge are food grade and completely harmless to yourself
and if accidentally consumed will be harmless to health. Their
presence will not affect the performance of the cartridge. If there
are still dust or particles present after this initial preparation,
then we would suggest that the cartridge is removed from the system
and re-prepared by: MAXTRA, Classic & Multifit cartridges: Vigorously
shaking under water, then re-install and flush through with two litres
of water. Inline, P 1000 & A 1000 cartridges: Flush a futher two
litres of water through the cartridge.
