My invention relates to a waste plug for baths and sinks featuring a flow/no-flow facility operated by centre pushbutton. Pushbutton (12) for flow, push again for no-flow. The underside is conically shaped (6) to help locate position on waste outlet. The plug can remain semi-permanent in waste outlet achieving a flow/no-flow operation by an internal high/low mechanism. High creates flow (30), low no-flow (32). The plug creates a seal on the waste outlet through contact with flange seal (3). This position is no-flow and flow position achieved when flange seal is raised out of contact with waste outlet flange. It also operates without flange seal by movement of stopper (14) from flow position to no-flow position when in contact with ring (2). The said plug is made from acetyl plastic and urethane flange seal, and a stainless steel spring. |
