Abstract: The cover or cap of a conventional pressure type flush valve is removed and a container is screwed onto the flush valve whereupon the cover or cap is then screwed onto the upper end of the container. A fine screen at the base of the container retains a granular or power type disinfectant, preferably in a bag, and a small tube is secured to the by-pass valve of the flush valve diaphragm and extends upwardly through the screen to adjacent the upper end of the container. The existing adjusting screw is removed and a longer screw screw-threadably engages the cover and extends downwardly through the container to control the action of the valve diaphragm. Each time the valve is actuated, the container evacuates carrying with it dissolved disinfectant which mixes with the water under pressure passing into the toilet or urinal.
