Abstract: A combination of a toilet and an anti refill device, the toilet comprises a bowl, a tank connected to the bowl for storing water and to supply the stored water to the bowl, a flushing structure which releases water from the tank into the bowl, a supply valve for refilling the tank with water after the flushing structure has released all the water into the bowl and a float structure for activating and deactivating the supply valve by floating in the water so that when the water is low the supply valve is activated and when the water is full the supply valve is deactivated. The anti refill device comprises a lock arm attached to the float structure and has an end, a lock device arranged to cooperate with end for controlling the lock arm and a structure activated by the flush structure which activates the lock device and the end to release the lock arm so the float arm lowers and the supply valve can fill the tank after flushing.

Abstract: A hollow cylinder or tube is buried in the ground with the upper end flush with or adjacent to the surface and a downspout from a building is connected underground through the wall of the cylinder to the interior thereof. A disc-like cover is mounted on the upper end of the cylinder for vertical movement so that when water passes through the downspout to the cylinder, the pressure moves the cover upwardly and allows the water to disperse around the periphery of the cylinder. When water stops flowing, the cover retracts upon the cylinder and seals it against the ingress of leaves, dirt and the like.
