ABSTRACT:
A retractable guard for use in combination with a sewage pipe leading from a flush toilet is provided having a plurality of prongs with hooked ends positioned within a cross section of the pipe. The prongs are connected to a piston which is slidable within a cylinder, perpendicular to the pipe. Flushing the toilet causes water to be directed in the cylinder which in turn partially retracts the prongs. Water may be diverted from the cylinder to wash accumulated debris from the prongs.
