Hello, Moved into a new house out in the country with well water. There's a pump in the basement along with a sediment filter housing. Everything seemed normal until we actually looked at it closely and ran some tests. Turns out that only the hot water passes through the filter -- there's another pipe for cold which bypasses it. I'm totally baffled as to why. If you're going to filter anything, wouldn't you filter drinking water? What's the logic behind filtering hot? Any thoughts would be appreciated.
