How To Use

The BOROUX Priming Pump is designed to work with the Boroux Foundation Filter, the Boroux Proactive Fluoride Filter and the Black Berkey Filter.

The below steps show how to prime the Foundation Filter using the Priming Pump.

1
Step 1

Set Up the Filter

Take the filter and remove the wing nut (leave the washer in place), and attach the filter to the pump. Rotate until snug — hand tighten only.

2
Step 2

Start Priming

Place the pump and filter in the lower chamber and hook it securely. Fill with water to the marked level on the pump, then press “On” and “Prime.” The pump will automatically stop when done.

3
Step 3

Final Check

Remove the filter and ensure the washer is secure. Repeat for each filter. If the water isn't clear, re-prime the filter.

Why Proper Priming Matters

The BOROUX Priming Pump helps safeguard against improper filter priming which can lead to:

Cloudy Water + Reduced Flow Rate

A partially primed filter typically has a slow and inconsistent flow, which is not only frustrating but can also indicate that the filtration process isn’t working efficiently.

Incomplete Saturation of Carbon Media

Activated carbon is porous and needs to be fully saturated with water to function properly. If it isn’t, air pockets can block flow and reduce the surface area available for adsorption, drastically reducing the filter's effectiveness.

Channeling Effect

Without proper priming, water can flow unevenly through the filter, creating channels that bypass much of the carbon media. This undermines contaminant removal and shortens the effective lifespan of the filter.
