What is the process of replacing a part or fixing something that is broken called?

The process of replacing a part or fixing something that is broken is best described as plumbing repair. This term specifically refers to the actions taken to fix plumbing systems, which may involve replacing damaged pipes, fixtures, or components to restore the proper function of the plumbing system. It is a targeted approach aimed at resolving specific issues or failures within the plumbing infrastructure.

While maintenance work generally encompasses all actions taken to ensure the ongoing performance and safety of systems, including periodic checks and preventive measures, plumbing repair is more focused on addressing immediate problems. Restoration typically involves bringing something back to its original condition, which might apply to historical buildings or artifacts, while refurbishment suggests updating or improving something rather than simply fixing a malfunction. Therefore, plumbing repair accurately reflects the specific action of addressing a broken part to restore functionality in a plumbing context.
