One of the problems with underground plumbing systems is the difficulty involved in inspecting them. Although materials used for plumbing lines today are generally of high quality and able to provide many years of service, damage can occur in hard-to-see areas from tree root invasion and ground shifts. The use of a camera to inspect underground sewer lines is becoming an accepted practice by municipal workers, plumbing contractors and those involved in the buying and selling of homes.
Closed circuit television (CCTV) cameras are used for pipe inspection work. The technology is now so good that the pictures obtained of the inside of pipes and drains are clear enough to easily identify any damage, or even any potential future damage, in the interior part of the pipe. Any build up of debris or dirt can also clearly be seen to allow the right approach of cleaning to take place later.
Camera Use for Home Inspections
A sewer camera is used to provide a visual inspection of inaccessible lines. Obstructions and damages underground or within concrete slabs can be viewed with a sewer camera. A video camera can identify collapsed pipes, corroded pipes, blockages from grease or other household elements, root infiltrations, pipes that are off-line due to ground settling and substandard pipe materials.
Reasons to Use Sewer Cameras for Home Inspections
Some homeowners question the cost of a sewer camera inspection, especially during home inspections for real estate transactions. Sellers generally want to minimize the expenses involved in the sale, but buyers often want assurance that their investment will not end up costing them lots of money right away in repairs. Spending a few hundred dollars for a sewer camera inspection versus several hundred dollars on plumbing repairs justifies the cost of such an inspection.
