CalPhos Polyphosphate Scale and Corrosion Inhibitor
The CalPhos venturi system is easy to fit and quick to fill up. This robust inhibitor is effective in preventing the hard build-up on pipes, shower heads, washing machines, boilers and other devices connected to the mains water. The inhibitor works by passing water through calibrated nozzles, creating a suction of polyphosphates and water solution from the bowl. A proportional dose is then delivered into the water system and calcium is prevented from crystallising.
The polyphosphate cartridges are long-lasting, replaceable and are 100% compatible with drinking water.
