Refil of Polyphosphate crystals

Can the Polyphosphate be replaced in this filter by changing out the crystals?
Asked by: Dauhee
Unfortunately we do not sell the Polyphosphate crystals separately, we would advise replacing the cartridge as a whole.

Hi, pls advise the filters installation position is correct or not. Thanks. Inlet water --> Sediment (1stage)---> Polyphosphate (2 stage) --out to house water supply.
Asked by: roblu
This is the correct order yes. Inlet > pre-filter > PP > outlet.

Are these cartridges FCPRA-10 compatible?

65 mm (2 1/2") diameter, 20 mm (9 7/8") long. They look like it, but I thought I'd better ask. Also, how much crystals (in weight) are in them?
Asked by: Gudinaf
I can advise that the PP cartridge is 74mm x 252mm (Diameter x Height). The quantity of polyphosphate contained within the cartridge is 0.9 kilo.

Are these cartridges supposed to be supplied sealed?

It arrived in a cardboard box but the filter itself is not wrapped. Just a bit concerned it may be a return.
Asked by: Ohtechyone
Due to the manufacturing/ordering procedure this item does not come wrapped and is boxed as standard.

How long does Polyphosphate Cartridge last? Or how often should I change it?

Asked by: MrDiscoDave
It is recommended that the PP cartridge be changed at least every 12 months, or sooner if the quality or flow of the water falls below a reasonable level for your intended use, or if the differential pressure across the cartridge reaches 1 bar.
