Acid water pH neutralizing filters use granulated calcite a naturally occuring mineral to raise the pH of acidic water. Calcite consists of pure calcium carbonate. Acid water will cause corrosion of plumbing and leaching of heavy metals such as copper, iron, lead and zinc into your water. Leaching of heavy metals from plumbing pipes can have adverse health effects. Acidic Water may result in costly plumbing repairs.
Copper is popular in domestic, industrial and commercial plumbing because it is easy to install and relatively low in cost considering its durability. Corrosion, or “pitting” corrosion due to acidic water is a major cause of failure in copper plumbing. After only a few months following the installation of copper plumbing, pitting can lead to pipe failure in the form of pinhole leaks.
The cost of plumbing repair and the associated expense of repairing water damaged appliances can be excessive. Pinhole leaks may go undetected in walls or basements for months. This provides an ideal environment for the growth of mildew or mold. Adjusting high-pH, low-alkalinity water will help reduce the occurrence of copper pitting and the problems it causes. The pH of water is a measure of how acidic it is. A pH of 7.0 is neutral. Higher values indicate alkaline water; lower values indicate acidic water.
On the average, water with a pH between 6.5 and 8.5 will probably not cause problems. However, the more alkaline the water is, the more likely it will be to have a “lime scale” build-up in the plumbing, especially if the water is hard. The more acidic the water is, the more likely it will be to cause metallic tastes, stains, blue-green from copper; orange-brown from iron, and corrosion of metal components especially copper plumbing.
A high copper content of domestic water usually manifests itself as a blue-green stain on white plumbing fixtures, particularly bathtubs. Sometimes it covers an entire bathtub. Sometimes the stain is just a streak under a leaking faucet. High copper levels in water can also be an indication that your pipes may develop pinhole leaks in the future.
Rain Water is acidic as low as pH 5.4 because some of the carbon dioxide which is present naturally in the air is dissolved in the water, forming carbonic acid. Acidic Water can be neutralized by the use of Calcite, which naturally adjusts the Ph to neutral or slightly alkaline.

CALCITE pH NEURALISING WATER FILTERS FOR WHOLE HOUSE WATER
Water Filtration Systems for neutralizing low pH water One of the most convenient methods to raise alkalinity is to use calcite neutralizing water filters.
These filters will typically raise the pH of the water to 7.0 even to 8.0 and add 30 to 50 ppm of hardness, depending on the pH of the water to be treated. In neutralizer filters, acidic waters slowly dissolve the calcium and magnesium media on contact as the water flows through the filter, raising the pH of the water and increasing the alkalinity. This eliminates the effects of corrosive water pH and helps prevent corrosion of plumbing and plumbing fixtures.
The size of the system is directly proportional to the flow rate of the water in litres per minute. The higher the flow rate, the larger the system required. Neutralizer filter tanks are filled with a blend of calcium and magnesium carbonates made from naturally occurring minerals, which dissolve into the water, making it less corrosive. More minerals can quickly and easily be added to the filter tank, typically once every 6 months for most residential applications. No special tools are required.
