Priming Button for Black Berkey Filters and PF-2 Fluoride Filters

Priming button used to prepare or prime the Black Berkey Elements for use in the Berkey system.

This foam rubber ring fits between a Black Berkey Element and a pressurized faucet to "prime" the element, eliminating tiny air pockets in the Black Berkey 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 Elements; in case of loss, the priming button can be purchased individually from this page.
