Water-saving manual toilet flapper valve

摘要

An improved water-saving toilet flapper valve (20) that calls for an end to automatic toilet flushing; instead it is operated manually. By manually depressing the toilet flush handle (72) for a desired amount of time, the user regulates the amount of water flushed down the toilet in a single session, thus saving water. A short flush interval or full flush interval can be achieved. This is accomplished by designing the flange body (50) of the toilet flapper valve to house a solid inner core (54) containing a weighted mass (56). This allows the toilet flapper valve to become non-buoyant when submerged underwater in a toilet tank (60). The flange body design is an improvement on prior-art since it acts as a flange to create a positive seal with the valve seat (68) of the toilet tank; thus preventing water leakage. This improved toilet flapper valve design can replace a standard toilet flapper valve without the need of additional tools or costly modifications.
