How to Set Up and Maintain a British Berkefeld Filter

The British Berkefeld gravity filter is one of the most trusted ways to get clean drinking water at home or in an emergency. To get the best performance, it’s important to follow the official setup and maintenance instructions.

This step-by-step guide walks you through assembly, conditioning, first use, cleaning, and replacement so your system continues performing reliably for years.

Unboxing & Parts Check

When you open your British Berkefeld system, you should find:

  • Upper stainless steel chamber
  • Lower stainless steel chamber
  • Lid with handle
  • Ceramic filter candles (Ultra Sterasyl or Ultra Fluoride)
  • Washers and wingnuts
  • Stainless steel spigot

Tip: Lay all parts on a clean surface and confirm everything is included before beginning assembly.

Assembling the Filter

  1. Insert each ceramic filter stem through the holes in the upper chamber.
  2. Secure from underneath using the supplied washer and wingnut. Tighten firmly by hand — do not overtighten.
  3. Install the spigot into the lower chamber using washers on both sides to ensure a proper seal.
  4. Place the upper chamber on top of the lower chamber.
  5. Position the lid on top.

Conditioning the Ceramic Filters (First Use)

British Berkefeld SS Gravity filters do not require a priming washer or faucet pressurization. The official instructions specify that the ceramic elements should not be pre-washed before first use.

Instead, condition the filters through normal gravity operation:

  1. Ensure the spigot is in the off position.
  2. Fill the upper chamber with cold water.
  3. Allow the water to fully filter into the lower chamber.
  4. Repeat this process for 2–3 full chambers.

The filters reach their maximum flow rate once fully saturated, typically after filtering a few full chambers.

You may notice small carbon particles in the lower chamber during the first uses. This is normal. Simply wipe the lower chamber clean if needed.

Important: Avoid spilling unfiltered water down the outside of the housing. If any spills occur, wipe them away immediately.

Cleaning & Maintenance

Over time, sediment collects on the outside of the ceramic filters, which can slow the flow rate. Cleaning restores performance.

To clean the ceramic filters:

  1. Remove the filter candles from the system.
  2. Gently scrub the ceramic surface under running water using a soft brush or scouring pad.
  3. Do not use soap, detergents, or cleaning chemicals.
  4. Rinse thoroughly and reinstall.

The stainless steel chambers can be cleaned periodically with mild dish soap and water. Rinse thoroughly before reassembly.

Filter Replacement Schedule

Replace filters once their rated capacity is reached or if performance no longer improves after cleaning.

The Bottom Line

Proper assembly, conditioning, and routine cleaning ensure your British Berkefeld gravity filter continues providing reliable filtration without electricity or plumbing modifications.
