Wassermann 20" Big Blue High Flow Housing
The Wassermann Big Blue (BB) High Flow Filter Housing with 3/4", 1" or 1.5" inlet and outlet ports can accept any 20” BB filter. The unit has a pressure release button to relieve water pressure when changing cartridges.
This high quality and robust housing comes with a hefty steel support bracket, a spanner for easy opening of the unit and fixing screws. If connecting to 15mm pipe, the 3/4" port size is recommended or 1" port size for 22" pipe and 1.5" ports for 28" pipe to maximise flow rates. The housing has female BSP ports and will require th correct fitting for the installation. Fit on cold water lines only and protect the unit from freezing.
When a filter change is required, the water supply to the housing needs to be switched off, therefore it is recommended to install isolating valves on either side of the unit in order to do so easily without turning off the mains water supply each time.
