A leaf filter for filtering solid particles from a liquid in a pressure tank. The leaf filter has a frame with a perimeter adapted to fit within the pressure tank. A flange with a groove in its outer surface, projects planar around the outer perimeter of the frame. The leaf filter has a filtering element with a perimeter that is larger than the perimeter of the frame. A cord is adapted to compressably engage the flange groove. The cord secures the outer edge of the filtering element to the groove thereby holding the filtering element planar and taut on the frame.
