How do I perform a Red Food Coloring Test?

Add 1 teaspoon of artificial red food coloring (we Recommend McCormick’s Red food coloring or any artificial food coloring) for every gallon that your Berkey® System can hold into the top chamber.  Place a cup under each Black Berkey® Purifier in the bottom chamber to catch the water.  As long as the water in the cups does not have a red or pink hue, the purifiers are working properly.

Ensure that you do not have the Berkey PF-2 Elements installed in the system when performing this test.  This test should be performed upon initial setup and every six months after that.
