According to the installation process, what must be done before centering the sleeve on a damaged pipe?

Before centering the sleeve on a damaged pipe, it's essential to prepare the pipe service. This step ensures that the area around the repair site is clean and ready for the installation of the sleeve, which is crucial for achieving a proper seal and functionality. Preparing the pipe service typically includes shutting off the water supply, draining the pipe, and cleaning the damaged area to remove any debris, corrosion, or contaminants that could hinder the repair. This foundational step is vital for the integrity of the repair process and helps prevent future leaks or failures.

Performing a pressure test can come after the installation to ensure the repair holds, while inspecting the pipe for further damage is typically part of the overall assessment before any service begins. Lubricating the gaskets would also be a later step, as it pertains to the actual installation process rather than the preparatory phase.
