New Zealand bore and roof water supplies are 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).

AquaFlo pH Neutralisers use natural minerals, such as calcium (lime) and Dolomite (heat treated to produce Akdolit) 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.

If iron and manganese concentrations are high, use a Calcite Filter, otherwise use an Akdolit Filter. If hardness is above 80gm/m3 CaCo3, consult with supplier.

The control of the filter system ranges from Forward Flow or Up Flow, Manual Backwashing to Fully Automatic (a time-clock allows adjustable backwashes from 1 to 6 days.

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.
