ABSTRACT:
A sewer relief valve assembly comprises a cylindrical sleeve dimensioned for insertion into a clean out which has an interior surface formed as a conduit and exterior threads adapted for mated engagement with the interior threads of the clean out. A valve means is disposed in the cylindrical sleeve which is displaceable from a closed position to an open position by pressurized fluid in the clean out. At least one perforated compartment is disposed inside the cylindrical sleeve which contains a water-soluble disinfectant composition. The valve means is displaceable by fluid pressure to the open position permitting discharge of the effluent through the clean out and the simultaneous release of the water-soluble disinfectant composition from the perforated compartment into the effluent. A water-soluble dye composition can also be included in the perforated compartment so that sewage overflow from the clean out is readily visible.
