Bad Water

My wife is on a holistic kick and is now insisting on buying a water filter for our kitchen faucet. No I have never been one to really complain about something like the taste of water and didn’t think that a filter was going to make something without much taste taste better. So we get the family together for another one of those Saturday morning family trips and go to LOWES to price them. After an hour of bickering she decides on the one she wants and the one I have the smallest chance of breaking when I install it. So half a day goes by and I get this thing installed and I must say that I can really taste a difference in the water. Ironically my wife still complains about the water tasting funny and now wants to look into putting all new cooper pipes in the house so as to remove any chance of the family ingesting rust, I guess I will never win.
