I installed the Ultra UC unit on the wall in the basement and I ran a hose from it to fill our emergency tanks - 150 gallons - plus we fill our 5 gallon bottles as needed for our kitchen water dispenser (the standard upside down bottle 5 gal type). It has been installed for over a year and have had no issues.
The water has always - from day 1 - tasted great. We had used other delivery services for 5 gallon bottles and also filled our own at Whole Foods, but I must say this is the best tasting of all of those. I never have to worry about the off-taste of the local water - along with the smell of chlorine. Fortunately for us our local water plant does not fluoridate the water, but it does come from a reservoir right by our house and I was concerned about the long term affects of radiation fallout on the water in the reservoir. With this filter I am no longer concerned about how or what might happen in the future.
I am going to purchase two new sets of filters so I can be ready for just about anything. I suspect if something does happen there will be a shortage of filters almost instantly, and this will go along with my other long term preparations.
One final note. Since the cost per gallon is now so low, we now give the dog this water and she does drink substantially more than with tap water.
