The image shows a close-up of a sink drain in a bathroom. The drain is made up of two white pipes that are connected to each other. The pipes are arranged in a horizontal line, with the topmost pipe on the left side and the bottommost pipe in the middle. There are two red and blue pipes on either side of the pipes, which appear to be connected to a pressure gauge. On the right side, there is a yellow spray bottle with a red nozzle. The background is a white tiled wall.
