Dear Douglas, When I came to US, I was horrified that people drank water directly from the faucet… and since I have recorded in my deep mind the boiling of water (custom widely applied in Mexico) I installed a katadyn/charcoal activated filter. Since that time, (10 years ago) I had cleaned the inside of the filter 6 times, not was clogged just disminished the water delivery. Here in Calexico CA the water comes from the Colorado River and it is really clear. I do not know how many parts per million contains of particles, but in Mexicali Mexico, when you fill the swimming pool, the water is turbid and needs to be filtered for 48 hours… Alex -----Original Message----- From: Douglas Haack [mailto:[email protected]] Sent: Wednesday, August 20, 2003 3:04 PM To: [email protected] Subject: CS>Your unfiltered water PPM ? Mr Garland, What is your normal daily unfiltered water PPM ? We live north of San Diego and our water source is the Colorado River at 350 ppm on average. Can one expect that your Berkfield filter may clog up much sooner with this ppm reading? I have avoided buying a Reverse Osmosis (RO) system because of this daily ppm factor. The Berkfield unit sounds interesting. By my own experience the present style or type of RO system is a bacteria trap!! i.e. Bacteria does pass thru the filters! For the following reasons: The older RO system I owned in Sydney required maintenance. i.e. Was recommended that one opened the reservoir container (RS) and actually cleaned the internal rubber bladder at least once a year. The 5 gallon metal RS had 6 small bolts that sealed the rubber bladder inside. The container had an external bicycle valve to add pressure around the rubber bladder -- inside the sealed metal RS. This was/is all very tedious, but, be patient!! The big surprise -- Upon opening the RS, pulled out the rubber bladder, inserted one's bare hand, one immediately felt a slimy residue lining the bladder. It was recommended that one clean this clear sticky slime build-up. Sydney water on average is 85ppm. fluorodated, disinfected etc etc. Not sure what the actual biological content of the slime might have been. This was some 5/6 years ago. It didn't seem to harm me! Thoughts of somehow using CS to alleviate this slime growth problem was seriously considered -- and then I moved to the US, without solving this challenge!! The type of RO system now sold at Home Depot etc at about US$160 including filters is a completely sealed unit. I'm not sure how they recommend one cleans this slime build-up out -- not sure if any mention is made of this fact at all, having never opened the box for the instructions etc etc. I would bet no mention is made of the "slime". Any qustions I've asked of water people have always been met with disbelief and blank stares! Maybe one could add a small tap arrangement and leak in some CS. Not sure how this might affect the delivery pressure -- probably based on the domestic tap pressure. Not sure about that. Of course buying new main filters (2) costs about $35 and with 350ppm one could go broke keeping filters up to unit. Does anybody have any ideas on how these sealed units deliver water under a small pressure?? Of course having local water content here of 350ppm would only clog up RO filters very quickly. Or that's what I believe! Unless someone can give me a good reason for this theory to be untrue!! We now have both distilled water and filtered water delivered from Arrowhead and I mix the two 50/50 into our own bottle. Tedious!! -- Arrowhead have delivered cracked bottles on two occasions and they nicely leaked silently onto our beautiful hardwood floors!! Buying water, an expense I'd like to save on, if any body has a suggestion, any contributions are sought. And distillers are a whole other story and I've done some research on those including the John Ellis system. Have the patent papers and his esoteric "living water concept" is not what is patented!! His defect warranty from memory is very poor too.

They are made of Ag impregnated diatomite and activated charcoal. A set is $35 retail. Should be good for 300,000 gal. TJ Garland, CMO supplier there are no incurable illnesses-only incurable people.
