4. pH remains neutral 7.0 -8.0 Nitrates reduce to zero when full water purification unit is Installed (This water went through old galvanized pipes) Corrosivity moves from negative range to positive range when full water purification unit is installed (The more negative the more corrosive the water)

5. pH remains neutral 7.0 -8.0 Nitrates reduced to zero. (This water did not go through old galvanized pipes) Corrosivity moves from negative range to positive range when full water purification unit is installed (The more negative the more corrosive the water)

6. pH was a little below neutral 6.0 - 7.0 Nitrates reduced to zero. (This water went through old galvanized pipes) Corrosivity moves into very negative range with or with out the purification unit installed. (The more negative the more corrosive the water)
