Patent ID: 10337179

Abstract:
A flood prevention apparatus for a sanitary ware product such as a bath or the like. The flood prevention apparatus comprises a multi chamber drain and an overflow apparatus. The multi chamber drain comprises a body defining at least a first and a second chamber therein. Openings into the body define a first outlet port and a second outlet port. Each of the first and second outlet ports are vertically and horizontally displaced relative to each other. The first outlet port is in fluid communication with the first chamber and the second outlet port is in fluid communication with the second chamber. The first and second outlet ports are each connectable to associated first and second pipe sections of the overflow apparatus. The overflow apparatus comprises a first pipe section configured to attach to the first outlet port and a second pipe section configured to attach to the second outlet port. The first and second pipe sections provide substantially vertical pipe sections. The first and second pipe sections are joined in continuous fluid communication by an inverted U-shaped passage, which includes a normally open air valve at its summit. The air valve is operable to control flow of water through the apparatus in a non-siphonic state.
