A method for moulding a sanitaryware receptacle the method comprising:—
- mounting a drainage device to an inner surface of a mould for a sanitaryware receptacle, the drainage device being positioned relative the mould such that the end regions of the drainage device coincide with locations of overflow and drainage apertures to be made in the receptacle once moulded;
- pumping moulding material into the mould thereby substantially surrounding the drainage device with the moulding material;
- allowing the moulding material to harden to form the receptacle;
- removing the mould from the moulded receptacle;
- locating end regions of the drainage device via the protruding members which are configured to protrude from the receptacle at the locations where the overflow and drainage apertures are to be made;
- making a drainage aperture through a base portion of the sanitaryware receptacle, the drainage aperture extending through the base portion and a portion of a first end region of the drainage device;
- and
- making an overflow aperture in the side wall of the receptacle and through a second end region of the drainage device and in doing so, opening a drainage passage defined by the drainage member which extends between the overflow and drainage apertures of the receptacle.
