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 may be purchased individually
PLEASE REMEMBER; When priming the Black Berkey purifier or PF-2 use only a slow water flow, spraying water when priming is not a water pressure issue, it is a water flow rate issue. Slow flow that is the Go!!!
