Claims29
An apparatus, comprising:
- a flush mechanism configured to provide for a predefined flush capability in a toilet;
- and
- a gasket detachably attached to the flush mechanism, the gasket forming a seal between the flush mechanism and a flush orifice of a flush valve, the seal being maintained during a full flush of the toilet by the flush mechanism, where the flush valve is configured to seat a sealing member.
A method, comprising the steps of:
- removing a sealing member from a flush valve in a toilet, the flush valve including a flush orifice that is sealed by the sealing member;
- positioning an adaptor having a gasket over the flush orifice of the flush valve so that the gasket comes into contact with the flush orifice, thereby creating a seal between the adaptor and the flush orifice;
- and
- attaching a dual flush canister to the adaptor with the gasket in contact with the flush orifice, the dual flush canister providing for a dual flush capability.
