Learning how to build a berkey water filter. The Berkey water filter operates on the principles of microfiltration and adsorption to ensure clean and safe drinking water. During filtration, water is passed through tiny pores that effectively block contaminants like bacteria, viruses, and heavy metals from entering the filtered water. Additionally, the activated carbon within the filter attracts and retains harmful chemical contaminants such as chlorine and volatile organic compounds.

The Berkey water filter system comprises several essential components:

The upper chamber serves as the entry point for water, where it undergoes purification using the filtration elements. The lower section collects the filtered water, while the reduction elements remove fluoride and arsenic. The filtered water remains free from potential contaminants with the system elevated by the base and protected by the lid.

  1. Berkey Stainless Steel Chambers: Upper and lower chambers form the basic structure of the filter system. These can be purchased as a part of the Berkey system kit from Berkey’s official website.
  2.  Black Berkey Purification Elements: These are the primary components responsible for water purification. They come with the Berkey system kit or can be purchased separately from the store.
  3.  Fluoride and Arsenic Reduction Elements: These optional elements can be added for enhanced filtration.
  4.  Berkey Base: This elevates your system for easy use. It is included in the system kit or can be purchased independently from Berkey.
  5.  Berkey Lid: Protects your filtered water from external contaminants. It comes with the system kit or can be bought separately on the Berkey site.
  6.  A Soft Cloth: This is to clean the stainless steel chambers. You likely have one at home; if not, they are available at local stores or online.
  7.  Non-toxic Cleaning Solution: To clean the chambers if needed. Available at most grocery or home goods stores or online.
  8.  A Flat-head Screwdriver: To secure the filtration elements. You likely have one in your tool kit; if not, they can be found at your local hardware store or Amazon.

Ensure you have all of these items handy before starting the process. The assembly will run smoothly if all the required materials and tools are within reach.

Assembling the Upper and Lower Chambers

Step 1: Positioning the Upper Chamber

Start by placing the upper chamber on a flat, steady surface like a table or countertop. The upper section is the one with holes in the base.

Step 2: Installing the Purification Elements

Next, take the Black Berkey Purification Elements. Insert the stem of each element through the holes from the inside of the upper chamber. On the outside, attach the rubber washer and wing nut to each branch and hand tighten. Be careful not to overtighten as this could damage the elements.

Step 3: Positioning the Lower Chamber

Place the lower chamber on the Berkey base. The lower section is the one without holes in the ground.

Step 4: Joining the Chambers

Finally, carefully place the upper chamber onto the lower section (with the purification elements installed). Ensure the upper section sits securely in the lower room. Your Berkey system is now assembled and ready for use.

In the following steps, we will prime the purification elements and complete the setup of the Berkey system. Read and follow these instructions carefully to ensure the best performance from your Berkey system.

Installing the Filtration Elements of Berkey Water Filter

Step 1: Preparing the Elements

Start by unwrapping the filter elements and removing any packaging materials. Inspect each piece to ensure there are no visible defects.

Step 2: Inserting the Elements

Next, insert the threaded part of each filter element into the holes inside the upper chamber. Each filter element should protrude from the outside of the room.

Step 3: Securing the Elements

Place a rubber washer over each protruding filter stem and hand-tighten the wing nut onto each branch. Be cautious not to overtighten as this may strip the threads or crack the plastic.

Pro-Tip: Hold the filter stem inside the chamber while tightening it to prevent it from spinning. Make sure each filter is straight and upright for optimal performance.

Step 4: Checking the Alignment

Inspect the alignment of the filters from the top. They should be evenly spaced with no leaning to the side. Adjust as needed for perfect symmetry. A proper alignment ensures an even flow of water through all elements, maximizing the efficiency of your Berkey system.

Your filtration elements are securely installed and ready for priming and use. Please check the fit periodically to ensure the system continues to function effectively.

The Importance of Priming the Filters

Priming your Berkey filters is an essential step in the filter installation process. This procedure saturates the purification elements with water, enabling them to filter out unwanted contaminants in your drinking water properly. Priming also ensures an optimal filtration rate and maximizes the lifespan of your Berkey filters.

How to Prime Your Filters

Step 1: Wet the Rubber Gasket

Start by wetting the tan-colored priming button (rubber gasket) in some water. This will create a better seal between the controller and the stem of the purification element.

Step 2: Attach the Priming Button

Attach the gasket to the stem of the filter element. Ensure that the hole in the button fully covers the gap in the branch.

Step 3: Prime the Filter

Hold the filter under your tap so the priming button faces down. Gently turn on your cold water tap. Allow the water to fill the cavity in the priming button, creating a seal.

Step 4: Check the Filter

You should notice water begin to bead up on the outer surface of the filter, indicating that the element is being primed. Continue this process until the entire exterior of the filter is saturated and beads of water form on the surface.

Step 5: Dry and Install the Filters

Once primed, turn off the tap and remove the priming button. Gently shake out any excess water and towel dry the filter before installing it into your Berkey system, as described in Section 4.

Remember to prime each of your filters before use to ensure the maximum effectiveness of your Berkey purification system.

Installing and Positioning the Spigot of Berkey Water Filter

Step 1: Prepare the Spigot

Take the fixture and make sure it’s clean and free of any debris. This will ensure smooth operation and minimize the chances of leaks.

Step 2: Install the Spigot

Insert the threaded part of the fixture through the hole in the lower chamber of your Berkey system. Ensuring the institution faces the desired direction for easy access is essential.

Step 3: Secure the Spigot

On the inside of the lower chamber, place the washer onto the threaded part of the fixture. Next, screw the nut onto the threaded portion, tightening it to secure the stopper in place. Be careful not to overtighten, which may damage the system or cause leaks.

Step 4: Test the Seal

Before using your Berkey system, fill the lower chamber with some water and observe if any leaks occur around the fixture. If you notice any, gently tighten the nut until the leaking stops. If the leaking persists, you may need to reposition the washer or replace it with a new one.

This careful installation will ensure a leak-free operation and a tight seal between the fixture and the lower chamber, ensuring the efficient functioning of your Berkey water purification system.

Why Perform an Initial Water Filter Run

Performing an initial water filter run is crucial in ensuring your Berkey system’s optimum performance. It helps flush out any residual particles that might be present in the newly installed filters, thus preventing their considerable accumulation over time. This practice extends the lifespan of your filter elements and guarantees the purity of your water right from the first use.

Steps for Completing the Initial Filtration Run

Step 1: Fill the Upper Chamber with Water

Pour water into the upper chamber of the system. Make sure to fill it to the brim. This will allow the complete saturation of the filter elements and ensure the removal of any lingering particles.
