  • Patent number: 5398348
    Abstract: A water urinal has a urinal body which includes a housing with an opening on its upper portion for receiving a valve used to supply flushing water to the urinal. The valve is attractively concealed within the body of the urinal and eliminates the necessity of embedding a valve in the wall surface on which the urinal is mounted. A cover, which covers and provides access to the valve receiving space within the urinal body, allows maintenance of the urinal without having to remove the urinal from the wall or break an opening in the wall.
