Priming Button for Black Berkey Filters and PF-2 Fluoride Filters
Priming button used to prepare or prime the Black Berkey Purification Elements for use in the Berkey system.This foam rubber ring fits between a Black Berkey Purification Element and a pressurized faucet to "prime" the element, eliminating tiny air pockets in the Black Berkey Purification Element to maximize flow. Also performs the same priming function for
the PF-2 elements.
The priming button is included in each set of Black Berkey Purification Elements; in case of loss, the priming button can be purchased individually from this page.
