Flush
In the construction industry, the word 'flush' typically refers to two surfaces or components being aligned or even with each other, creating a smooth, seamless transition without any protrusions or gaps. If two materials or surfaces are flush, they are perfectly level or aligned, allowing them to fit together without any offset or overhang. This term is commonly used when describing the alignment of walls, panels, or surfaces within a building structure.
However, the word 'flush may also refer to a process of washing out of an installation with water in order to remove debris, such as flushing a wc or flushing pipework.
