Instructions for testing filter elements with powdered color
1) Remove white fluoride/arsenic filters, they must not be tested with color.
2) Place the upper chamber on jars or glasses so that a jar is positioned under each filter element; this way, you will know which filter element is working and which one is not.
3) Dissolve up to 1/4 of our food color in a bottle of water, stirring or shaking thoroughly until the sediment disappears.
4) Fill the upper chamber of your Berkey with clear water halfway.
5) Add the colored water you have prepared (the water should not be heavily colored, excessive color can damage the device)
6) Fill the upper chamber with clean water to the top.
7) Wait for the jars to fill.
8) Check if the water in the jars is completely colorless. If not, locate the non-functioning filter element.
9) If all elements are functioning properly, immediately discard the remaining colored water, rinse the upper chamber, and refill it with clean water. If the colored water passes through, save the colored water for a later retest.
10) If you notice that any of the filters fail to remove the color, check the wingnuts, check the filter element thread, check if the rubber washer is placed inside the chamber, check if the filter element is properly installed and tightened according to the instructions. Is it overtightened? Is the thread damaged? Use only your fingers, no tools.
11) If the element continues to leak color, let us know!
12) Do not test the Sport Berkey bottle.
How much coloring is too much?
