The purpose of a spirit level in construction is to check for horizontal or vertical alignment. This tool is essential for ensuring that surfaces are level (horizontal) or plumb (vertical). When the bubble within the vial of the spirit level is centered between the lines, it indicates that the surface is perfectly aligned. This accuracy is crucial for various construction tasks, such as installing cabinets, framing walls, or laying tiles, as it ensures that structures are built correctly and function properly. Accurate alignment contributes to the overall quality and safety of construction work, making the spirit level a fundamental tool in a plumber's toolkit.
