A Black Berkey Primer tool can help you prime your water filters when water pressure from a sink is not available to use the priming button. Black Berkey water filters work best when they are fully saturated with water prior to use. This can be accomplished by forcing water into the drip tube and out the pores of the filter. But when you don't have water pressure, this can be difficult. The Black Berkey primer tool solves this problem.
The Black Berkey primer tool comes in a small plastic bag with instructions on how to assemble it. There are two tubes, two stop valves, a 90-degree angle hose adapter, a Black Berkey stem adapter, and the pump.
