Product Details
A replacement cartridge for our CT600 Polyphosphate Doser system (see here).
This cartridge adds a food grade hexameta polyphosphate material to the water which prevents scale from forming on heating elements, baths, showers, etc.
It also inhibits corrosion (rusting) and prevents acidic water from dissolving copper pipework.
The cartridge has a typical life of 6 months - we will send you a reminder when a replacement is due.
