When disaster strikes
When there is a disaster the devastated areas always need clean water. Emergency help often arrives late so it's important to have a back up system of your own for survival until supplies can be brought in on a larger scale. Our portable filtration system is extremely simple to use and rather easy to maintain. Anytime we look for something new we want it to be safe and easy to use and that is our goal here. Simplicity and mobility have to be part of our design - that's why we recommend smaller buckets for portable use and larger buckets or containers for group gatherings or stationary use.
What is a Gravity Feed Water Filtering System made of?
It's a simple two-bucket system, one bucket mounts on top of the other. The buckets or containers are usually plastic and they can be almost any size - two-gallon, five-gallon or ten-gallon. The size really doesn't matter. For easy get away, our family filter fits into a two-gallon bucket. The two buckets stack together with the filter mounted inside and the lids stacked on top of each other. For a larger family or a bigger group, it might be more practical to start with the five-gallon bucket so the water supply is ample for the group.
How to Assemble a Ceramic Gravity Feed Water Filter in a Bucket System?
Assembling a filter begins by drilling a 1/2" hole in the bottom center of the top bucket and another 1/2" hole through the lid of the bottom bucket. The holes should be directly in line with one another. Ignore drilling procedure if the holes are already there.
This next step may vary depending upon the space that exists between the lid of the bottom bucket and the bottom surface of the top bucket. Some buckets have a raised rim at the underneath bottom center of each bucket that will leave a gap for the water to leak through. It may be necessary to use both flat washers between the lid and the bottom of the top bucket to fill the gap so water does not leak into the clean water through the lid of the bottom bucket.
The filter comes with two 1/2" flat washers. Assuming your bucket isn’t like the one described above leave just one flat washer on the stem of the filter and lower the filter assembly carefully down into the top bucket. As you lower the filter gently align the shaft so it fits through the base of the bucket. If the hole is too tight you can take a pocket knife and lightly scrape the hole to ease the assembly of the shaft.
Take the second 1/2" flat washer and install it on to the shaft after you assemble the lid of the bottom bucket to the bottom of the top bucket. In other words the second washer goes on just before the wing nut and it is meant to provide a seal if water accidently settles into the lid of the bottom bucket.
Once the lid, the filter and wing nut are fitted together, gently tighten the wing nut to prevent contamination or leakage. Be cautious and do not over tighten the nut so much it stresses and cracks the filter or its stem.
Now let’s do a leak test as follows...take a cup of water and pour a thin layer of water into the top bucket but be careful not to add so much it begins to run through the filter element. Also take a cup and pour a little water into the top of the lid where it attaches to the top bucket. Let the water sit in both places for 20 to 30 minutes and then carefully raise the bucket up and inspect to make sure no water has leaked around the wing nut where the shaft goes through the lid. If there is a leak, it needs to be fixed to prevent unfiltered water from entering the bottom bucket where the clean water is supposed to be. The fix may be as simple as switching the flat washers to a different position as described above.
It will also be necessary to install a 3/4" spigot to the bottom bucket. The hole is drilled deep into the sidewall of the bucket, but not so far down it makes it impossible to screw the nut onto the shaft of the spigot. When installed the nut fits on the inside wall near the floor of the bucket. If the hole is drilled too low in the side of the bucket the nut will interfere with the floor of the bucket making it impossible to install the spigot. If the holes too high you won’t be able to get all the water out of the bucket. It’s best to use the nut to determine the positioning so you’ll know exactly where to put the spigot hole.
For anyone who's not good with details, we provide a complete ready-made pre-drilled kit that is already to use in case of emergency. This filter kit includes a protective sock that fits over the filtering element that can be secured with a rubber band or a light weight string.
Securing the sock is particularly good where extreme turbid water and contaminants are noticeable such as fish scales, fecal matter and etc. When you put water in the top bucket it slowly passes through the filtering element and trickles down through the filter shaft on into the bottom bucket at the rate of approximately 1 gallon per hour. If the water flow becomes too slow a scotch pad can be used to gently "lightly" scrub the outer surface of the filter.
For a small to midsize family it is recommended you have at least two of these filter kits on hand so you can say "I have a year's supply".
A Ceramic, Half-micron Water Filter
The small micron size opening removes water-borne bacterium. The inside of the filter is loaded with different media or ingredients, such as man-made carbons, mother nature made carbons and man-made resins. Those different resins and carbons remove the different contaminants in the water.
How long will a Ceramic Filter and its Parts Last?
Once you start using the filter, the activated carbon is only good for 6 to 8 months. The anti-bacterial ceramic wall will work indefinitely. The media inside [such as the activated carbon] will pack over time. The filter needs to be shaken to unpack the media. The shelf life of the unit itself is indefinite. The only question is the carbon. Current figures say the unused carbon should have a shelf life of 2 to 3 years, maybe more. The sock has an indefinite shelf life. Replacement during use will depend on the filthiness of the water source.
Freezing temperatures can damage a filter. The best place to store a filter kit is indoors to avoid freezing temperatures.
BUYER BEWARE - Since there was a decrease in availability for the larger 4 x 4 water filters an inferior replacement emerged into the market confusing people.
Here’s a list of things to look out for when buying a quality water filter for your protection.
- The amount of charcoal in the water filter. The larger the filter the more room there is for charcoal.
- The diameter of the filtering surface. The filter with the largest diameter makes the water travel through more charcoal before it drips through the center hole.
- The overall construction of the filter and the precaution taken to prevent the water from potentially running around the filtering element. Notice the larger filter with the black base - it has an obvious sealer around its base and dome; whereas the smaller one is questionable since it’s not visible.
- The overall weight of the filter can tell something important about the quality of the filter. It tells you which one contains more ceramic material and charcoal.
- Another good comparison would be to gently shake the filter to see how much charcoal is inside the filter. If you hear a lot of movement that’s a good indication there is very little charcoal inside the dome. Less movement within the filter indicates the volume of charcoal is greater.
- The drain hole in the bottom of the filter may affect the flow ratio. The larger filter in this case has the bigger drain hole.
Quick helpful tips and hints to identify the filter you’re buying.
- The color of its base.
a. The filter with the white base is usually smaller.
b. The Larger Filter normally has a black base.
- The filters dimensions.
a. Smaller filter is approximately 3-1/2” x 3-7/8”
b. Larger filter is approximately 4” x 4”
- The weight of the filter tells a big story about its filtering content.
a. White base “smaller filter” weighs approximately 8 oz.’s.
b. Black base “larger filter” weighs approximately 13.1 oz.’s.
- Size of drain hole.
c. White base “smaller filter” drain hole approximately (.019) ID.
d. Black base “larger filter” drain hole approximately (.022) ID.
