ABSTRACT:
A container is detachably secured to the overflow pipe in a toilet tank and holds soluble disinfectant. A tube connected to the water inlet valve branch normally connected to the overflow pipe of the tank with the inlet valve and the outlet of the tube being controlled by the float valve. This tube includes a T-fitting, one leg of which extends downwardly through the cover of the container to adjacent the base. The other leg extends to the overflow pipe for restoring the water seal in the bowl after flushing. A venturi in the T-fitting extracts water containing dissolved disinfectant from the container, when a toilet is flushed, thus adding disinfectant to the bowl and to the water seal. A further T-fitting is provided in the tube upstream of the first T-fitting and is situated above the water level in the tank in order firstly, to act as a siphon breaker and secondly, to divert some of the water flowing to the overflow after flushing and during filling of the tank when the water inlet is open. This prevents the excess water beyond that required for replacement of the water seal, from discharging into the overflow. Apertures adjacent the upper end of the container permit filling of the container when the tank is full and transfer of the disinfected water within the tank to the water in the tank.
