In thousands of homes on well water, acidic water causes thinning of copper pipes, pinhole leaks, and numerous copper pipe leaks over time. Acidic water filtration systems can easily correct and neutralize a low pH in well water. The pH scale is a scale from 1 to 14. A neutral pH is 7. A ph of less than 7 is considered acidic. A pH greater than 7 is considered alkaline and is less corrosive to copper pipes than waters with a pH of less than 7. Signs of acid water are corrosion of fixtures, blue staining (from copper pipes) or rust staining (from iron pipes). Acidic water can also cause pinhole leaks and pipe failure over time. By raising the pH to the range of 7.0 to 7.5 the water can be made alkaline which will then reduce or eliminate pipe corrosion. Common causes for acidic water are acid rainfall d Kitchen Unit Doors ue to atmospheric carbon dioxide and other airborne pollutants, runoff from mining spoils, and decomposition of plant materials. Acidic waters can be of good quality and are typically low in buffering calcium minerals, but are high in dissolved carbon-dioxide gas, which can cause the low pH or acidity. Calcite Neutralizer Filters An acidic water filtration system is also known as a calcite neutralizer filter. One of the most convenient methods to raise pH, and add a little hardness and alkalinity is to use a calcite neutralizer filter. These filters will typically raise the pH of the water to 7.0 to 8.0 and add 30 to 100 ppm of hardness depending on the alkalinity and water hardness. The water will taste better and in most applications no water softener will be required after the calcite neutralizer filter.
