The Black Berkey Primer is a hand-powered priming pump that makes it possible to prime Black Berkey Elements easily offline, without the need for faucets or hose connections. Priming the Black Berkey Elements saturates the filters with water prior to their use, allowing for clean water production anywhere. The Black Berkey Primer also purges (or back-flushes) the Black Berkey Elements using air instead of water to clean the proprietary pores of the compressed carbon filter wall.
Purging the Black Berkey Elements accomplishes two tasks: (1) It clears the pores of debris that has accumulated with use, (2) reduces the amount of time and effort needed to dry the filters prior to storing them. In addition, those who may be having difficulty priming their elements in a small sink can use the Black Berkey Primer instead.
