Video is OK but a live assistant would be better

I like the Big Berkey. The water in our town is bad and it makes me feel better to know that I'm swallowing clean water. The only problem I had was setting it up! I'm an 85-year old female who lives alone and all that assemblage was quite a project. Had to call someone for assistance in twisting and tightening the spigot, the plugs, the knob on the lid,etc. My fingers are not very strong anymore! NOW that it's put together, I'm quite happy with it.

Our Berkey

A few years ago we got our first Berkey when the water in the Animas River was contaminated by decisions made by the EPA…then we went on to get another Berkey for each of our daughters. Our latest Berkey is in Ware, Massachusetts since the water quality is so poor there. Our neighbors got a Berkey on our recommendation and have recommended it to many others there. I guess we have probably sold in excess of a dozen Berkeys for you and we will be needing one more for our Grandson as he begins his single life.

Pretty Good

I’ve had my Big Berkey about 6 weeks, and so far I like it but it’s impossible to know how full it is in order to keep it full, and when I overfill it leaks, so often it’s half filled and then I run out of water unexpectedly and have to wait for it to filter through which is slow and inconvenient. The water comes out somewhat slow, especially when it’s not full, and I find that 2.5 gallons isn’t big enough for my family of 2 because it seems like I’m filling it up at least twice a day. Maybe it’s just me using it wrong? The instructions that came with it on how to assemble were like reading hieroglyphics so we used a YouTube video instead to assemble. it’s possible I missed some tips or something that might make using it easier. When the water comes out, it has bubbles in it, almost like soap bubbles but there’s no soap in the Berkey. I’m not sure if that’s normal or not. But in terms of taste, it’s wonderful. Very clean tasting (that is, no taste at all, the way water should be).

Berkey Feedback Note

My husband and I like The Berkey very well. The water tastes good. The only thing I wonder about is that it makes my coffee real dark in color even though I make my coffee not too strong. It also makes Tea dark in color. But both taste good. So we like it well, it works great for us two and I have to drink 64 ounces of water per day on the Ideal Protein diet program I am on. My husband just looked up how long the filters would last on this and looks like 2 to 3 years for us two.
So all is good. Thanks. My brother Tom Walsh in Cumby, TX is the one who referred us to The Berkey.
We give The Berkey a good rating!
