Assemble and Clean Water Filter

Detailed Instructions

Shopping Water Supplies

    To store, assemble, and clean water filter follow these instructions.

    Two same-size buckets are needed. Wastebaskets to #10 cans may be used as long as the containers are suitable for potable water.

Spigot Installations:

Steps 1-3 Assembling Dome Water Filter

    1) Drill a ½” hole in the bottom of the top bucket and in the middle of the lid of the bottom bucket. If you buy a lid that is pre-drilled, line up the hole in the bottom of the top bucket with the hole in the lid of the bottom bucket. The bucket is drilled with the lid. There will only be one way that they will fit together.

    2) Drill a ¾” hole for the spigot along the bottom rim of the bottom bucket.

    3) Remove the spigot from the packaging.

Steps 4-6 Assembling Dome Water Filter

    4) Insert the spigot into the ¾” hole from the outside, using one washer.

    5) In the interior of the bucket, screw on the wing nut. Hand tighten.

    6) Turn the spigot by hand, clockwise, one full rotation (hand tighten only).

Steps 7-9 Assembling Dome Water Filter

    7) Fill the bucket with water and check for leaks. If leaking occurs, repeat steps 5 and 6.

Filter Installation:

    8) Remove the filter from the packaging and clean water filter with cold water and cloth or 3m Scotchbrite pad. (Once it gets wet, the charcoal inside the ceramic shell will last 6 months.)

    9) Put washer on stem of filter.
    Note: Be careful not to apply pressure or ‘torque’ on the water tube. To do so can cause the ceramic dome to crack around the base.

Steps 10-12 Assembling Dome Water Filter

    10) Insert the filter stem through the filter hole with the filter upright in the bucket. This should be tight. Hold onto the plastic base and gently screw the filter into place.

    11) Tighten the wing nut on the filter stem. If leaking occurs, repeat step 11.
    Put the felt water sock onto the ceramic dome and hold it in place with a rubber band. This will help to keep the dirt away from the filter, thus prolonging the life of the filter. The sock can be removed for cleaning.

    12)Pour the dirty water in the top bucket and dispense the clean water out of the bottom bucket.

Filling Instructions:

    To retain a constant capacity, always add the same amount of water to the top bucket that you will be dispensing from the bottom bucket.

Cleaning Instructions:

    Remove the filter and clean water filter sleeve and buckets every two weeks with hot water and soap. Clean water filter in cold water with a soft toothbrush, 3m Scotchbrite pad, or fine sand paper. (Never use hot water and soap when cleaning water filter). Re-install filter and proceed as normal.

    The need to clean the water filter goes down when you pre-filter the water first. That is why we recommend the giant water sock. (link coming soon)

Flow Rate:

    It usually takes several days for the flow rate to increase to 1 gallon per hour. The flow rate will increase as the interior and mixed media becomes completely saturated.

    The flow rate might also be slow because the filter is dirty. If this is the case, clean water filter and fill the top bucket.


    If the ceramic water filter freezes, it will crack.

    The ceramic absorbs the moisture from the air. When the water vapor in the filter freezes, it cracks the filter. One solution is to always store it indoors. Another option is to ‘can it’ in a #10 canner or Mylar bag with some oxygen absorbers. An airtight container will keep the ceramic filter from absorbing moisture from the air.

    You can store the pieces of your water kit in the nested buckets.


    The shelf life of the ceramic filter itself is indefinite. The anti-bacterial ceramic wall will keep working until the ceramic wall has been worn down from cleaning and scrubbing.

    The ceramic wall on a new filter is 3/8" thick. Each time you clean water filter, the ceramic wall gets thinner. (The filter can be cleaned about 100 times)

    Replacement of the filter will depend on the filthiness of the water. The cleaner your contaminated water, the less often you will have to scrub your filter.

    Once you start using the filter, the activated carbon in the filter is only good for about 6 months. The activated carbon inside will pack over time. The filter needs to be shaken to unpack the carbon.

    Current figures say the unused carbon should have a shelf life between at least 2 or 3 years, if not much more.

    There is a difference between the life of the ceramic part of the filter (8-12 months) and life of the activated carbon (6 months). So what do you do? The ceramic part of the filter will continue to work in filtering out bacteria, but your water might not taste as good.

    Here's a solution. Buy some activated charcoal in the fish section of the pet store. After the six months of using your filter are over and you notice that your water does not taste as good as you would like, add the new activated charcoal to the top bucket of the filter. (We'll talk about how to make your own charcoal on the "make your own filter page" - link coming)

    The small sock has an indefinite shelf life.
