a pressure differential between the fluid source pipe 12 and the filtered fluid outlet pipe 14 the fluid then contacts the filter media 43 resulting in the removal of suspended solids and the filtered fluid then moves into the interior volume of the filter stalk 41 then into the interior chamber 38 of the rotatable valve assembly 30 and exits the rotatable valve assembly 30 via the filtered fluid outlet port 34 an additional feature of the invention disclosed herein allows for the simple and quick removal and replacement of the filter media 43 without the need to remove the entire filter assembly 10 from the piping system to change the filter media 43 or filter stalk 41 the user may simply shut off fluid communication to the filter assembly 10 pull set clip 25 out of the header assembly 20 and remove the rotatable valve assembly 30 and filter element assembly 40 from the filter housing assembly 50 the user can then remove reinstall and or change the filter media or an entire filter stalk as the need arises the user then reassembles the filter assembly 10 in the reverse order of the steps outlined above reinitiates fluid communication with the filter assembly 10 and resumes filter operations fig5 is a perspective view of a backwash flushing filter assembly in accordance with another embodiment of the invention disclosed herein fig6 is a profile cross sectional view of the backwash flushing filter assembly of fig5 shown in the assembled.
