Artificial Red Dye Test for Black Berkey Water Filters

How can I tell if my Black Berkey Elements are working correctly? (Red Dye Test)

When doing a red dye test, make sure the Artificial red dye contains FD&C Reds 40 & 3(read product label)

 INSTRUCTIONS:

Performing the Red Food Dye test on Black Berkey Elements.  (Test is especially recommended for untreated water)

  1. Protect surfaces and clothing, gloves are recommended.
  2. Make sure black washer orientation is correct, Washers must be installed inside the upper canister
  3. Start with an empty system (upper and lower chamber) and remove any Berkey PF-2™ Fluoride and Arsenic Reduction Filters(if installed). The Berkey PF-2™ Fluoride and Arsenic Reduction Filters must be removed prior to performing a red food coloring test in order to stay in compliance with the six month warranty on the Berkey PF-2™ Fluoride and Arsenic Reduction Filters .
  4. Place the upper chamber only (with the elements installed) on similar- sized cups directly underneath each Black Berkey This will help isolate which filter may be exhausted and which is still purifying effectively.
  5. Fill the upper chamber with water and add 1/8 teaspoon of ARTIFICIAL red food coloring for every gallon of water. Must contain FD&C Reds 40 & 3. (Read product label)
  6. Allow the water to run through to the bottom chamber. Place clear cups or mason jars below each filter.
  7. If the red food coloring is removed entirely, your purification system is working properly.
  8. If the water in any of the cups is red or has a pinkish tinge, then that particular black filter is defective or exhausted.
