Double pipe system

A double-walled pipeline can be created by pulling a welded PE sewer pipe into an already installed sewer pipe or using a factory-prefabricated double-walled pipeline. If necessary, the double-walled pipeline can be extended all the way into the house. The tightness of the pipeline can be easily monitored using built-in shut-off devices for filling and venting. No other system offers the same level of tightness and controllability of the pipes and shafts.
