How CCTV Drain Inspection and How it Can Help your Home?

June 12, 2015

CCTV pipe inspection involves using a remotely operated camera that is mounted on a self-propelled robotic crawler. The crawler moves inside and through the drain line, transmitting video images as it moves forward. A video monitor is located in a van type vehicle where the inspector or operator studies the video as it is transmitted by the robotic camera through the drain line. CCTV push cameras are typically used for pipes having diameters between 40 and 150 mm. Tractor cameras with pan tilt-lens are used for larger pipes that have diameters exceeding 100 mm.

CCTV inspections should be performed within the established guidelines of the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment Certification Program (PACP). Operators and data analysts should also be PACP certified to help ensure the mobile camera is operated properly, and the data is analyzed correctly.

CCTV drain pipe inspections offer a variety of proactive benefits as well as checking for problems and damage. Homeowners are also advised to use CCTV as a general maintenance inspection tool. CCTV inspections are recommended for home buyers and insurance reports as well. Homeowners are responsible for maintaining their sewer and drain lines, and CCTV inspections can immediately reveal any damage, problems, or potential issues that might interrupt easy flow.

CCTV quickly identifies drains that are blocked by roots, or which are collapsed, bellied, or broken and disjoined. Performing drain inspections with CCTV saves time, excavation errors, and expense for the homeowner.

  • CCTV inspections easily locate damaged or leaking pipes without disturbing or causing more above-ground disruption to adjacent patios, gardens, or driveways (cost saving efficiency).
  • It is imperative to have drain line, sewer line, or septic line inspections done before purchasing or selling a home.
  • Damaged or blocked drain and sewer lines can cause water or sewerage to back up into the house.
  • Bad smells, structural damage, and dangerous toxins may be caused by leaking drains. Water leaking out of drain pipes can saturate surrounding soils and loosen foundations, footings, and structure supports. Material surrounding the structure can easily get sucked into and down the drain leaving the pipe, as well as the structure, unsupported.

Home CCTV inspection may also be necessary:

  • to determine what might be undermining the foundation,
  • to examine structural conditions or damage,
  • to verify drain field leakage and conditions of pipe inflow and infiltration,
  • to determine the size and type of existing drain pipe construction (so the correct connections may be made),
  • to locate service laterals,
  • when drains run slowly or appear blocked,
  • when it is suspected that only sink waste, flushings, or garden debris might be backing up the system,
  • when roots, grease, cross-bores, and debris must be located,
  • when it appears the drain is suddenly blocked (indicating a cracked, broken, or collapsed pipe), or
  • when the usual methods of finding the problem or determining how to fix a leak or blockage does not work.

A remotely controlled CCTV camera can diagnose the cause, isolate the area so an exact digging location can be decided, and what type of repair is necessary.
