Abstract: An overflow valve cover includes a planar surface having a first surface and an opposing second surface. The planar surface includes a plurality of openings spaced apart along on the planar surface. An angled slat is positioned within each of the plurality of openings. A top edge of a collar is affixed to the circumference of the planar surface. A connector is positioned on the inner surface of the planar surface and extending away from the second surface.

Abstract: A positioning structure for assembly of the water faucet plaquette has a plaquette having front face, a depressed back and a through-hole. The depressed back of the plaquette has a bent positioning claw. A wall permanent seat has a plaquette assembly surface, an abutting surface and a fixed portion. The fixed portion is positioned fixedly onto the wall. The plaquette assembly surface of the wall permanent seat is fitted with limit surfaces, which are aligned transversely with the positioning claw. A soft liner ring is fitted with at least two slots that are fitted onto the positioning claws. The limit surface has a pair of tabs and a vertical lug engaged with the position claw.
