I had written a review of my berkey water filter when we first purchased it in 2014. We have been using it nonstop, putting approximately 1 gallon per day through it from our city tap water. If you refer to the photo, you can see the layer of fine sediment (dirt) coating the bottom two-thirds old filter. Note that the filter was still working fine, the water tasted great, but the upper tank of the filter wasn't draining because of the clogged filter. It was taking a full night to filter just 1 gallon of water. After replacing the (2) filters, we are now filtering a gallon in less than an hour.
Below is the letter that we sent to Berkey (and their response). Enjoy!
We have been using our Royal Berkey Water Filter for 10 months now, and I wanted to post some quick feedback.
Where we live, most of our neighbors have well water. Our place is one of the "lucky few" to have city water. So, when people used to come over and drink our tap water, they usually made "that face." They tasted the chlorine right away.
