  • Patent number: 10626587
    Abstract: An overflow device for an appliance such as a bathtub, sink or the like. The overflow device comprises a body which connects the overflow device to the appliance. The body includes a body inlet adapted to be connected to an appliance outlet. The body also includes a body outlet adapted to be connected to a soil stack. A drainage flowpath is defined between the body inlet and the body outlet. In use, the drainage flowpath creates a water seal between the body inlet and body outlet. The overflow device also includes a pipe arrangement in fluid communication with the body, where the pipe arrangement defines an overflow flowpath between the body inlet and the body outlet, such that, in use, at least a portion of the overflow flowpath is beneath the level of the water seal.
