The water coming out of my filter is black or grayUpdated 2 months ago

Why does this happen?

Some brand new filters can let fine carbon particles into the water due to the way they've settled during manufacturing or transport. This is completely normal and safe.

How to fix it

Simply flush the system — run water through the filter a few times — until the water runs clear.
