  • Patent number: 10988919
    Abstract: A shower floor former assembly is provided which comprises a shower floor former having a non-circular waste-plate receiver and a drain waste plate which is dimensioned to be receivable in the waste-plate receiver. A centre point of the waste-plate receiver is offset from a centre point of the shower floor former, and the drain waste plate has a drainage aperture therethrough, a centre point of the drainage aperture being offset from a centre point of the drain waste plate. The drain waste plate is receivable in the waste-plate receiver in a first condition in which the centre point of the drainage aperture is offset relative to the centre point of the shower floor former. The drain waste plate is also receivable in the waste-plate receiver in a second condition in which the centre point of the drainage aperture is coincident with the centre point of the shower floor former.

  • Patent number: 8403647
    Abstract: A control device for controlling a shower waste pump, includes a housing, a pump setting, and an over-run setting. The pump setting, by way of a control element, preferably a manually adjustable potentiometer, allows selective setting of a maximum pumping capacity of the waste pump. The over-run setting, also by way of a control element, allows selective setting of an over-run period from a predetermined range during which the waste pump continues to operate after fluid flow through the waste pump has ceased or substantially ceased. The over-run setting and the pump setting together optimize operation of the waste pump, so that the over-run period of the waste pump can be set based on the selected maximum pumping capacity.

  • Patent number: 8312596
    Abstract: A hinge assembly (4) for the connection of two panels (10, 12) at their adjacent edge regions (8d) to allow said panels to rotate up to 360 degrees relative to one another, the hinge assembly comprising an elongate member (20) providing two opposing curved surfaces adjacent the edge of each panel, said member co-operating with at least one pair of intermeshed gears (24), the assembly including connector means (34) for attaching each panel to said member and a bubble seal (22) disposed between the edge of each panel and each curved surface of the member.

  • Patent number: 8150245
    Abstract: An electric shower water heater unit for connection to a water supply and a mains electricity supply comprises a housing having a shower water outlet to which a shower hose is connectable; an electric water heater housed in the housing and fluidly connectable to a water supply outlet of the water supply and electrically connectable to the mains electricity supply, the electric water heater supplying water to the shower water outlet of the housing; a user-operable controller (20) for controlling a temperature and a flow rate of water supplied to the shower water outlet of the housing, and a control circuit which is housed in the housing and which controls the electric water heater based on inputs received from the user-operable controller (20). The user-operable controller includes a touch-pressure sensitive element (40, 49) for pressing by a user and which is in communication with the control circuit.

  • Patent number: 8096002
    Abstract: A height-adjustable shower waste for a bathroom floor having a non-flexible waterproof floor covering material, the shower waste comprising a waste body (12) for mounting in the bathroom floor and having a base (20), one or more sides extending from the base (20), a waste water inlet (26), and a waste water outlet (30) connected or connectable to a drain; a cover support element (16) on which a cover element (18) is or can be provided to cover the waste water inlet (26); distance setting means (54, 66) for selectively setting a distance between an in use upper edge of the cover support element (16) and the waste body (12); and retaining means (90, 104) for positively retaining the cover support element (16) at the said set distance. A method and an adapter device are also provided.

  • Patent number: 8006325
    Abstract: A pumped shower drain system (10) comprises a shower base (12), a waste water unit (14) provided on the shower base (12) and having a waste water inlet (28) and a waste water outlet (30), and a reciprocating water pump (20) for pumping water from the waste water unit (14) to a drain (22). The reciprocating water pump (20) includes: a pump housing (40) having a pump inlet (48) in liquid communication with the waste water outlet (30) of the waste water unit (14), and a pump outlet (50) in liquid communication with the drain (22); first and second inlet valve seals (56, 58) in spaced relationship; and first and second outlet valve seals (84, 86) in spaced relationship. Each set of inlet and outlet valve seals comprise different kinds of valve seals from each other, and are independently closable to close the pump inlet or outlet. Preferably, the inlet valve seals and/or the outlet valve seals have different modes of operation.

  • Patent number: 7975328
    Abstract: An upward discharge waste device for a shower tray, comprises a hollow housing having a waste water inlet, a waste water outlet and a flow-channel for waste water between the waste water inlet and the waste water outlet; and a mounting element for mounting the waste device over a waste outlet of the shower tray. The flow-channel has a non-uniform transverse cross-sectional shape along the longitudinal extent from the waste water inlet and towards the waste water outlet, but has a uniform or substantially uniform transverse cross-sectional area along the longitudinal extent. A shower tray having the waste device is also provided.
