What are the dimensions of the Berkey Light™
System?
Height x Diameter (inches) 26.5 x 9.25 (base included); The system can also be used without the
base and stands 21"; Empty Weight 5(lbs); Holding capacity: Aprox. 2.75 Gallons.
The
weight of the Berkey Light™ system is 5 lbs. Berkey Light™ systems are now
BPA Free In the past the Berkey Light™
systems were made of food grade polycarbonate that has been approved by the US Food and Drug Administration. Some research
suggests that polycarbonates have been known to leach BPA (Bisphenol-A) when either exposed to High Strength Industrial Grade
Alkaline Detergents or when they are repeatedly exposed to temperatures in excess of 192 degrees Fahrenheit (over 88 degrees
Celsius); neither of which occurs when utilizing the Berkey Light™ system. New studies concerning the possible leaching of BPA are ongoing. However, recently there has been a wealth of mis-information
circulated over the airwaves and the Internet. The FDA stated in April that it is not recommending anyone discontinue using
products that contain BPA while they continue their risk assessment process. Even
with such statements from the FDA, New Millennium Concepts has determined that it is in the best interest of our customers
to begin utilizing an alternative to the polycarbonate previously used to produce the Berkey Light™
system. Fortunately, just this year (2008), a new product was developed that is BPA FREE. New Millennium
has replaced the polycarbonate material with this new material to alleviate any concerns that our customers might potentially
have. Not only is this new copolyester highly durable and dishwasher safe, it is also scratch, stain, shatter and odor-resistant.
PLEASE NOTE: Over the past year there has been an increasing concern
over containers that contain the recycle code #7. The recycle code found on the bottom of plastic containers are called "Resin Identification Codes". Polycarbonate is simply one type of plastic that falls under the code #7. Code #7 is a catchall code that
basically means "Other" and most products that do not fit into categories #1 through #6 are placed into category
#7. It is also for products that are made from more than one type of plastic in category #1 through #6. The new copolyester
that the Berkey Light™ system utilizes is also categorized into #7 although it is not
a polycarbonate and does not contain any BPA. |
I can’t get the
chambers to snap together, am I doing something wrong?
Please make sure you are aligning the seams, as most
of the systems will not snap together unless the seams are aligned. If that doesn't solve the problem, please measure
the opening on the lower chamber from seam to seam. The diameter should be at least 7 15/16" or greater.
If it is less than that please call customer service.
What
is the most convenient method for filling the upper reservoir?
Most people use a pitcher to pour water
into the upper chamber however, if you have a spray hose on your sink, using it to refill the system is a very convenient
method.
The
water in the upper chamber of my Berkey® system does not drain all the way. Is this normal?
Yes it is normal and not unusual for the last 1/2" to 1" of water to remain in the upper chamber. By design
the water must pass through very fine micro pores within the elements in order to pass from the upper chamber to the lower.
The lower the water level in the upper chamber, the lower the pressure available to force the water through the micro pores.
You might have noticed that the system purifies much faster when full than when half full. That is because there is
more pressure. The only way to remedy the problem would be to enlarge the pores within the filter elements. That
would of course, reduce the efficiency of the purification elements. During each cycle the water left from the previous
cycle mixes with the water from the current cycle and is then purified. You should not be concerned about the excess
water during normal use however if you discontinue using your filter for a period of time such as during a vacation, it would
not hurt to empty the upper chamber before departing.
I have been using my system for about six months and the flow rate has slowed down
considerably. Do I need to replace the elements?
No, unlike other filtration elements Black
Berkey® purification elements are re-cleanable. What typically causes the filters to drip slowly is
turbidity and sediment clogging the micro-pores of the purification elements. Simply remove the elements from your system,
scrub the exterior of each element with preferably a white ScotchBrite® pad or stiff toothbrush. Simply scrub
a section of the filter until you see a bit of black on the white pad then move to the next section. It’s simple
to do and takes less than a minute. Then re-prime each element and reinstall them. Your problem should now be fixed.
How do I know when it
is time to replace the elements in my system?
The best way to gauge when to replace the filters is to do
the following:
Multiply the
number of filters in your system by 3,000 gallons to get Total Gallons For All Filters within the system.
Next keep a track of how many times you need
to refill the upper chamber in one week.
Then
multiply that figure times the capacity in gallons of your particular system (for example the Berkey Light™
system is 2.75 gallons) to determine Total Gallons Used Per Week.
Finally divide the Total Gallons Used Per Week into the Total Gallons For All Filters
and that will tell you how many weeks before the filters should be replaced.
Next calculate the future date for replacement (52 weeks per year) and write that date
on a sticker and attach it to the bottom of your system for future reference.
By the way, if you have been using your system for some time now,
you can still use the above formula to determine when to replace the elements. Just count forward from the date you purchased
your system.
I
will soon be leaving the country. Is there a way to test my Berkey® system to make sure it is working properly?
Yes, anytime you plan on taking your system out of the country we advise that you always perform the following
test prior to leaving. You should test your filters by filling the upper chamber with water then add a tablespoon of red food
coloring for every gallon of water within your upper chamber. If the red food coloring is removed entirely, your filtration
system is working properly. If not, check to make sure that the wing nuts on your elements are securely tightened then re-run
the test.
By the
way, always prime new purification elements before leaving the country, as you may not have enough water pressure to be able
to prime the elements at your destination.
I just purchased a Berkey® system but the system is hardly filtering any water at
all. Am I doing something wrong?
Typically the problem you are experiencing is due to high water tension,
which prevents the air from being purged from the micro pores of the new purification elements. Included with your Black
Berkey® elements is a priming button and instructions for use. Please remove and prime your
purification elements, reinstall them and that should fix the problem.
I have found that when I boil the water or freeze it into ice cubes, I sometimes
get little white floating things in the water. What is this bacterium?
With respect to the little
white floaters in the water, it is not bacteria but rather a problem that sometimes occurs with hard (heavily mineralized)
water. When water is filtered through your system, the Black Berkey® purification elements
actually increase the PH of the water. This is healthful as Pathogenic bacteria and viruses thrive in acidic environments
and conversely have difficulty surviving in alkaline environments. This is also true inside your body. When the
PH level of the purified water is raised, the acidity of the water goes down and the water is no longer able to hold as many
minerals in solution. When this happens the minerals begin to precipitate out over time and depending on the mineral
composition they will either sink to the bottom or float to the top. This process is known as flocculation and the precipitated
minerals are usually referred to as "white floaters". The bottom line is that this is nothing to be concerned
about, the white floaters are minerals that were already in your water; they are now simply visible whereas they were previously
invisible due to their suspension in an ionic form.
I did a TDS reading on the purified water and was surprised to find that the reading
was about the same with the purified water as it was with the unpurified water. Is my system working properly?
Yes, a TDS meter measures only Total Dissolved Solids or minerals; dissolved solids are simply dissolved minerals in an
ionic form. A TDS meter does not measure the amount of biological and chemical contaminates. Black Berkey®
elements are designed to leave in your water the healthful and beneficial minerals and to extract only the unwanted heavy
metals such as lead and mercury as well as sedimentary minerals such as iron oxide and aluminum. Therefore, your TDS
reading will not change much unless you have a significant amount of heavy metals or sedimentary minerals in your water.
