What does 2 stage whole house mean?
I have fitted a unit to the incoming mains water and it is a single unit but says on the guidelines that if using for whole house I should use this cartridge but I don't understand the 2 stage reference ????
This replacement cartridge is 1 of the 2 filter cartridges used in the BWT 2 Stage Whole House Scale Reduction System (product code 72063). This is a sediment filter cartridge which would be fitted into the first housing and the next housing would be fitted with a polyphosphate cartridge. This is what is meant by '2 Stage'. The filter cartridge you have been supplied with is suitable should you wish to filter sediment from your incoming mains water.
