Product review (5 stars): Ensure your Water Filter is actually engaged completely
I have purchased probably six of these filters over the last 3-4 years. There have been times I noticed the water had a medicinal taste. Upon inspection I discovered the filter had become disengaged from the water line. Apparently If you tap the cover hard enough say with the vacuum cleaner, or your boot/shoe etc. it will disengage. If you start tasting any change in your filtered water, make sure to push the button to ensure the filter is fully disengaged then push the filter back in to ensure it attached to the water line. I actually cut a piece of cork from a wine bottle to fit behind the button to ensure it wouldn't become separated from the water line if hit or kicked accidentally. Hope this helps. :- )
