ABSTRACT:
A filter assembly having bypass valves to allow continued liquid flow during the removal and reinsertion of a new filter. The assembly includes a cylindrical filter housing threadedly mounted to a valve housing with a cylindrical filter removably mounted within the filter housing. The valve housing has an inlet connectable to a source of liquid. A first valve is rotatable from a filter position directing all liquid flow from the inlet to the filter to a bypass position directing all liquid flow from the inlet to the outlet of the assembly. A shut off valve prevents liquid flow into the filter when the first valve is in the bypass position.
