Wife Anon just reported that the tap water we keep refrigerated really tastes nasty all of a sudden for no as yet explained reason; glad we have the Berkey water purifier, been running water through that for several years. We can use a new pair of filtering units though, because even though the elements are usually fast when they're new and clean, they can be slower than Christmas when they're old and dirty. Glad we've got 12 gallons or so stored, because when I asked her to try the Berkey water she said that tastes pretty good, much unlike how the tap water has suddenly started to taste. So soon as all that happened, I thought I'd better let you know
Watch the water!
Berkeys are really easy to find, they've got distributors all over the internet; they're expensive, but worth it
