would like to take a moment to describe the basic drain cleaning methods and tools of the trade.
SNAKING: The process of feeding a cable through drain lines to cut out, retrieve, or scrape away obstructions (tree root, scale, paper). This is the most common method used to clear drains initially. Aka. Rooting, Cabling.
CAMERA INSPECTION: The process of feeding a camera lens mounted at the end of a fiber optic cable through drain lines to visually identify problems (condition, breaks, offsets, build-up etc...) Aka. Video Inspection, TV Inspection or Televising the sewer.
PIPE LOCATING: The process of using hand held wand to pinpoint exact location and depth of camera head in underground pipe line. This is how you locate problems for repair.
HYDRO JETTING: The process of feeding a nozzle on the end of a high pressure hose to essentially power wash pipe walls. Commonly used to clear grease and sediment. Aka. Jetting or shooting.
