Priming

Before use, it is necessary to prime the Black Berkey and PF-2 filters. This is sometimes
easier, sometimes more challenging. This is due to compressed air being trapped in
the filters; it needs to be flushed out. This operation is called "priming". You need to be
patient because some filters are more difficult to prime than others. Follow the step-
by-step instructions to prime your filters correctly.
1.
Place the brown ring onto the Black
Berkey screw thread.
2.
Position the brown ring against the tap
and let the tap flow smoothly. The water
now slowly flows into the filter, which
gradually becomes heavier.
3.
The water drips slowly out of the filters.
It looks like the filters are sweating.
