New Zealand bore water supplies can be naturally acidic, some as low as 4.5 pH. Most are around 6.0 – 6.8 pH. At these pH levels, the water is a natural solvent and will try to correct itself by absorbing minerals/metals from pipes, taps and tanks. A lot of the minerals/metals contained in the water are toxic to humans in larger doses (i.e. lead, zinc, copper and others). Calcite is ideal for applications where iron and manganese are also present in the water supply.

The FILTEC range of Calcite Neutralisers use a natural mineral, Calcium (lime) to raise the pH level of the water into the desired range. The low pH water takes up these minerals until it reaches a stable state. This prevents the water from corroding pipe work, PLUS makes your drinking water safer to drink without high lead, zinc or copper levels.

The system connects to the main waterline to your home and treats all incoming water. Units can be fitted with blending valves to control pH levels.

The range consists of a variety of sizes and that use advanced fully automatic controllers for residential or commercial applications

If hardness is above 80gm/m3 CaCo3, consult with FILTEC or one of our Partners prior to installation
