The sewer basket is to be positioned at any selected level within a vertical sewer pipe having an interior surface and an opening at street level without in any way modifying the same. A basket support is provided comprising an expandable support for extending entirely around the interior surface of the sewer pipe and having at least one pair of opposite spaced free ends that define inturned ears through which a bolt extends and the ears are spread apart by nuts screwed on the bolt. For a sewer pipe of circular cross-section, the basket frame and the support frame are both of circular shape, the expandable frame having a single pair of spaced ears with a single bolt extending through the ears. For sewer pipes of quadrilateral shape, both the basket and the support frame are similarly quadrilateral, the support frame being made of two U-shaped sections each having opposite free ends defined by inturned ears and a bolt with nuts extending through each pair of ears. In another embodiment, the support frame is a telescopic tube with sewer engaging pads at both ends and with a pair of bolt and nuts tube expanding devices on each side of the tube.
