We have been in our new home for 7 months now and the water has a bad metal taste. We are on well water, which tastes fine before it gets into the house. Our plumber installed a water filter on the output of the storage tank. This, I assume is for sediment? I have tried several different filters (charcoal, etc) with no improvement. So I am guessing the taste is from the copper piping. Will the bad taste go away or do I need to place to install filters at each sink? Thanks Charlie C
