Combimate Combiphos Refills Pack Limescale Prevention ‘O-ring’ seal included Size: 800g Cisternmiser Combimate Combiphos Refills Pack Combimate is a user-friendly domestic limescale prevention device that uses Combiphos to deliver guaranteed prevention of limescale and soft water corrosion water control, with no moving parts. Combiphos is a polyphosphate compound specifically developed to provide the most effective limescale prevention in flow-through installations. Polyphophate dosing has been safely used to treat water throughout the world for many years.There are two installations options when fitting Combimate: Whole-house supply - For this installation Combimate should be plumbed in after the stop-valve on the cold water supply to the premises. The white removable divider tray should be removed from inside the Combimate dome in a whole house installation so that the dome can be completely filled with Combiphos (the full 800g bag contents). Single appliance - Combimate can be used to protect a single appliance by placing it on the cold water supply to that appliance (e.g. a boiler), in which case the red removable divider tray should be left in place and Combiphos should only be put in the top half of the dome. This reduces the amount of Combiphos required for annual topping-up (in this situation, the 800g bag will last two years).
