Abstract
A flapper assembly for a flush valve as well as method of assembly are provided. The flapper assembly includes a frame and multiple buoyancy assemblies attachable to the frame so as to adjust the buoyancy of the flapper assembly. The flapper assembly kit may have adjustable legs attachable to the frame. The flapper assembly kit may have multiple seal members for use in sealing with different sized/shaped valve seats of different sized flush valves.
Claims20
A toilet flapper assembly kit comprising:
- a frame including a buoyancy assembly attachment having a buoyancy assembly attachment interface;
- a first buoyancy assembly attachable to the buoyancy assembly attachment interface, the first buoyancy assembly providing a first amount of buoyancy when attached to the buoyancy assembly attachment;
- and
- a second buoyancy assembly attachable to the buoyancy assembly attachment interface, the second buoyancy assembly providing a second amount of buoyancy when attached to the buoyancy assembly attachment, the second amount being different than the first amount;
- wherein:
- the frame includes:
- a) a main frame, the buoyancy assembly attachment is attachable to the main frame;
- b) a pair of adjustable legs adjustably attachable to the main frame, the pair of legs being adjustable in at least one of a spacing between the legs or a length of the legs;
- a first seal member having a first characteristic for sealing with a valve seat of a first size flapper valve assembly;
- and
- a second seal member having a second characteristic for sealing with a valve seat of a second size flapper valve assembly, the second size being different than the first size.
