发明名称 METHOD OF INSPECTING AND PREPARING A PIPELINE
摘要 A sewer preparation from the main (PFM) device provides for the inspection and preparation of the sewer pipe from the main sewer pipe. The PFM device provides for the insertion of one or more individual and separately controllable tools into the sewer pipe. The tools include a clean out tool and a camera. Each of the tools is controlled separately such that each tool can be inserted and retracted from the lateral as desired. A method includes the steps of inserting and operating separately controllable tools from a single preparation device that provides access to the lateral without a cleanout or other alternate access passage.
