To temporarily block a pipe, use a pipe plug or a test plug. These are designed to provide a watertight seal in a pipe temporarily. First, choose a plug size that matches the internal diameter of your pipe. Insert the plug into the pipe and tighten it according to the manufacturer’s instructions—usually by hand or with a wrench. This solution is perfect for temporarily stopping the flow during repairs or when testing plumbing systems. Always ensure the plug can withstand the pressure and is suitable for the type of fluid in the pipe.
