Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces potential leaching of copper, lead and other metals found in typical plumbing systems. Periodic backwashing will prevent packing, reclassify the bed and maintain high service rates. Depending on pH, water chemistry and service flow, the Calcite bed will have to be periodically replenished as the Calcite is depleted. As the Calcite’s calcium carbonate neutralises the water, it will increase hardness and a softener may become necessary after the neutralising filter.
Water with a pH below 7 is acidic and corrosive. Raising the pH will neutralise the water, removing the metallic taste and pipe corrosion, and can also reduce any iron or manganese contamination.
The backwashing head has the advantage of remixing the media and removing any debris or iron/manganese. Backwashing the units stops the media compressing and stops it going hard which can happen with in/out systems.
This pH neutralisation unit is supplied partially assembled for shipping. Some assembly will be required. All components and instructions will be supplied. Below is a list of our residential and commercial calcite filters with Clack automated control head. Some of the residential filters can be bought on-line – for commercial filters please use our contact form.

About the Clack Valve:
Automatic Control Valves for backwashing Water Filters and Water Softeners,
Clack Automatic Control Valves are made to automatically backwash water filters and water softeners. Clack automatic valve are designed for residential, industrial and commercial applications with flow rates of up to 120 litres per minute, and backwash capability of servicing up to 22 inch diameter tanks requiring Inlet/Outlet fittings from 1″ to 3″.
The valves act as a primary centre that directs and regulates all cycles of water softening for filtration. They can be set to performs down-flow and up-flow regeneration or simply backwash and rinse. Clack valves are available in different program versions and are controlled by solid state microprocessors with front panel settings and screen display.
Fully automatic valves that provide efficient backwash cycles.
- Solid state microprocessor with easy access front panel settings
- Three modes of operation; meter immediate, meter delayed, or time clock
- Economical and simple to operate
- Calendar Override feature to ensure filtration media fresh and clean
- Double backwash feature offers efficiency, optimum regeneration and cleaning ability
- Stores system configuration and data in non-volatile memory
- Treated Water regenerate refill
- Down-flow and up-flow regeneration
- Low Salt Alarm
- Inlet and Outlet Fitting Connections from 1″ to 3″
- 12-volt output AC Adapter provides safe and easy installation
- Control valve design provides optimum service and backwash rates
