Most sewer lines can be returned to service within a few hours to one day, depending on the curing method used and the size of the project. Some modern curing techniques, such as steam or ultraviolet (UV) curing, allow the liner to harden more quickly than traditional ambient curing methods.

Once the liner has fully cured and the final inspection is completed, normal use of sinks, showers, toilets, and drains can usually resume. Your plumbing professional will provide specific instructions based on the curing process used during your installation.
