A strainer for filtering solids from liquids having a screen assembly comprising a filter support for supporting a filter comprising a cylindrical member having an axial opening therein;

• means of supporting said assembly in the strainer;
• said filter being made of a somewhat flexible material and being circular in shape having a perimeter and having an axial opening therein which aligns with the axial opening in the filter support;
• a support ring positioned about the perimeter of said filter and tensioning means for securing said filter to said ring which includes folding said perimeter about said ring and applying radial tension on said perimeter such that the filter is maintained thereabout with the ring secured within said filter, and said filter and said ring being supported by said filter support.
