Product review (3 stars): you have to flush at least 10 oz through again or the water taste like charcoal or metal
Not a huge fan of this product..  If the water outlet has not been activated for more than 8 hours..you have to flush at least 10 oz through again or the water taste like charcoal or metal.  I did the initial flush of several gallons when installed. I will not send these back...but will not order again either.
