Gravity Flow Water filters, are Replacement Filters Interchangeable?

I recently was asked if the replacement filters in the large gravity flow water filters were interchangeable.  By this, I am talking about the AquaRain, the Berkey, Doulton and Katadyn gravity flow water filters.  While all of them claim to be the best, my research show that they are all good quality units.

I have had quite a bit of exposure to the Berkey, AquaRain and Doulton gravity flow water filters.  My exposure to the Katadyn is more limited.  All of these filters work on the same principal.  The water is poured into the top container and by the action of gravity flows though the filter into the lower container. …

The Importance of Knowing the Water Sources Near Your Home

Having access to good water sources are an important prep.  I have a creek right across the street from my house; it is probably 50 feet from my front door.  Up the hill from my home, there is a natural spring and it has always ran a small stream of water down the hill by the side of my home. I have lived here since 1987 and until this year, the spring has always been reliable. I have spoken to older residents that say they can remember that spring running 50 and 60 years ago.

This year the spring has dried up.  …

The Doulton Travel Filter, a Solution to Water Problems When Traveling

 

The other day while I was up at the FreezeDryGuy’s sale I was looking through the various water filters that he stocks and found some Doulton travel Filters.  Now these are a nice little unit that reminds you of a miniature stainless steel Berkey.

Doulton filters have been made in England since 1815, and were used throughout the British Empire.  They are not as well known in the US as in other countries.  Doulton are sold in the US, but more for whole house filters.

My wife and I travel quite a bit and it seems we often run into horrible tasting water in some of the places that we stay. …

Water Assurance: An Inexpensive Device

Here is another article from a friend on a plan to backup your water.

Howard

Water is a concern for us as a family. In the area where we live, we do not often face droughts but they do occur. During one of the dry spells, some of the shallower wells in the area began to run dry and that can really get you thinking. What would happen if. . .

No doubt people living in areas served by public water could have similar concerns but for other reasons.  We need look back only as far as last summer when a toxic algae bloom in Lake Erie led officials in Ohio and Michigan to ban tap water for over half a million people.…

Water can be Your Most Important Prep

water

Here is another entry in the contest, this one is about water.

Howard

You have posted several articles about water, which I think is THE most important prep of all preps.  Being a former water operator I know how important it is to have water that is safe to drink.  I’ve seen the shows on TV where people have thousands of rounds of ammo but, maybe, only a few hundred gallons of water at most – for several people!

The average American uses roughly 75 gallons per day.  A family of four will use over 2000 gallons in a week!  Even just using water for drinking, food preparation and basic sanitation (to promote normalcy), they will still use over 100 gallons a week. …

A Review of the Sawyer Mini Filter

A while back, I picked up a four pack of Sawyer Mini Filters.  Since then I have been playing with them and have grown to like them for use in a bug out or get home bag.  They are also good for use in your everyday carry.  With a weight of only 2 ounces and being very compact, they can easily fit in your pocket.

The Sawyer Mini Filter is rated to 0.1 micron absolute, weighs only 2 ounces, and filters up to 100,000 gallons.  Now personally I can’t see anyone ever running that much water through one, but it is nice to know that the capacity is there.…

Converting 275-Gallon Totes to Use a Hose Bib

The 275-gallon food grade totes are great for long-term water storage and building rain catchment systems.  They normally can be purchased relatively inexpensively.  The one problem with them is that that can come with different types of threads on the valve and spout that is located at the bottom of the tank.

During the last couple of years, I have helped distribute a number of these totes to friends near where I live.  The built in valve on the tanks are plastic and while I have not had any fail, I don’t entirely trust them for daily use. Adding a hose bib gives you additional protection against losing your water from a leak.…

Learn How to Pasteurize Your Water Without Boiling

This is a update of an article that I posted several years ago on how to pasteurize your water.  It explains how you can pasteurize your water without bringing it to a boil.  In an emergency this little device can save you fuel by shorting the time in which you have to heat your water.  It is inexpensive, reliable and can be reused indefinitely. research indicates that it has proved effective in third world countries.

Because of its low price $7.00 you can afford to purchase several.  It is small and will store almost anywhere.  The downside to it is that it does take a heat source to work and it will not remove chemicals or other contaminates.…

Your Water has Failed What to Do Next?

purifying waterThe grid has just failed for one of many reasons, running from earthquakes to economic collapse.  You are without power and don’t know when it will come back on, but it appears that it will be at least several days.  So one of the first things you need to think about is protecting and using the water you have on hand.

If you have any warning, fill your bathtub and other containers.  Then shut your water off at the street if you are on a municipal water system.  This will protect the water in your piping and water heater from becoming contaminated from outside sources.  …

Purifying Water with Chlorine Bleach and Pool Chlorine

purifying waterA lot of this information has been posted on this blog in the past, however I still get questions on it so I thought I would cover purifying water with chlorine again.

I see FEMA, the American Red Cross and others all recommending liquid Clorox, Purex or chlorine as a method for purifying water in an emergency.  Bleach can be a good method of water purification, except they don’t mention that liquid bleach has a shelve-life.

Clorox states on their website that bleach should be replaced every year.  This is for laundry use.  For purifying water, bleach has started to lose its strength at six months.  …
