CARE OF YOUR BERKEY SHOWER FILTER™ AND "BACK FLUSHING."
The effectiveness of the Berkey Shower Filter™ removing Free Chlorine depends on the quality of the water source and
age of the Berkey Shower Filter™. A reduction of water flow may occur over time. Should this happen, a “backflushing"
procedure to break apart the media and rejuvenate the Berkey Shower Filter™ can be done to help:
BACKFLUSHING INSTRUCTIONS:
1. Remove the Berkey Shower Filter™ from the shower arm.
2. Remove the shower head from the Berkey Shower Filter™.
3. Turn the Berkey Shower Filter™ around and attach the backflushing
coupling (supplied) to the outlet of the Berkey Shower Filter™ (See
Fig. D).
4. Attach the coupling to the shower arm.
5. Turn on the shower and flush the Berkey Shower Filter™ with warm
water for several minutes at full flow.
6. Remove the unit and reassemble using Teflon joint sealing tape.
FILTRATION MEDIA
The Berkey Shower Filter™ contains a new and improved shower filtration media, which is most effective in reducing
Free Chlorine, Hydrogen Sulfide, Scale and Iron Oxide (rust water). The Berkey Shower Filter™ media works in a wide
range of temperatures with a maximum operating temperature of 110 °F (43 °C) temperature.
How Long Will Your Berkey Shower Filter™ Last?
The length of time the Berkey Shower Filter™ lasts with optimal reduction of Free Chlorine levels in your shower
depends on a variety of factors. These factors include the level of Free Chlorine, pH balance, amount of water used, the
hardness of your water and the care of the unit. Under average water conditions, the Berkey Shower Filter™ typically
lasts 25,000 gallons or one year, whichever comes first. To extend the lifetime, backflush regularly.
Please note testing performed under standard laboratory conditions, and actual performance may vary.
USING A FLOW RESTRICTING WATER HEAD
The Berkey Shower Filter™ showerhead incorporates a patented feature that regulates the water flow rate 2.5 gallons
per minute (GPM) from water pressure as low as 15 (PSI) to pressures as high as 100 (PSI). This feature not only results
in substantial energy and water savings, but it also is an essential part of the Berkey Shower Filter™ design. The flow
restricting feature of the Berkey Shower Filter™ head ensures the proper contact time of the water within the filter.
DO NOT USE SHOWER HEAD WITH FLOW RATE GREATER THAN 2.5 GPM AT 60 PSI. DOING SO REDUCES THE
EFFECTIVENESS OF THE BERKEY SHOWER FILTER™.
NOTICE OF LIMITATIONS:
• The design of the Berkey Shower Filter™ is for potable water systems only.
• Do not allow to freeze, or use with water over 110 °F (43 °C) temperature.
• Maximum water pressure should not exceed 100 (PSI).
• Do not use in high iron content water systems that use chemicals such as polyphosphates.
• Do not drink water from the Berkey Shower Filter™.
