Abstract: An automatic dispenser for disinfectant and bowl cleaning material adapted to be suspended stationarily in the tank of a flushing bowl wherein the dispenser comprises a container with ball valve floated against the tapered interior of an upper opening in the container and an adjustable drainpipe in the bottom of the container with the adjustable drainpipe having an upper tapered opening and a ball valve for closing the same as well as lower openings extending downwardly outside the container providing passage for container water or tank water as the case may be. In operation the two ball valves are floated to the top of their respective openings sealing the openings and isolating the water in the dispensing container. The dispensing container is provided with preferably a block of soluble disinfectant cleaning material such as a hypochlorite which will dissolve very slowly into the water in the container.
