Title: Isn't working
Product review: I don't know why, but this D-20A filter is not working as well as the D-20 (which I cannot find anywhere). My well water still has that 'boiled egg' smell and now (this was not happening prior to putting in this filter)there are tiny flecks of black 'stuff' in the water, which I believe may be particles of the charcoal filter. Very disappointed as they were a great price. I'll try my local hardware again as they seem to work well. Going to have to cancel my renewable order through Amazon. Very disappointed.
