CIPP is considered a trenchless technology, meaning little to no digging is typically required, for a potentially more cost-effective and less disruptive method than traditional "dig and replace" pipe repair methods. The liner is inserted using water or air pressure, applied via pressure vessels, scaffolds or a "chip unit".
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
