If you’ve done any research on sewer line problems, you’ve probably seen something about “sewer cameras” or “video pipe inspections.” Any plumber worth their salt uses this technique when diagnosing sewer backups or sewer pipe damage, so it’s wise for homeowners to know what sewer camera inspections are and what they’re used for should a sewer problem ever arise.
HOW SEWER LINE CAMERAS WORK
The purpose of the sewer camera is to be able to see what is causing the blockage or backup inside the drain pipe without digging your backyard and leaving a mess or just guessing what the problem is. Because sewer repair and pipe replacement is not a small task, it helps homeowners avoid expensive repairs without knowing for certain that their problems will be solved when the work is done.
A small, flexible sewer camera is attached to the snake-like cable that plumbers feed through the sewer pipe until it reaches the cause of a blockage (or breaking a line). The radio transmitter on the camera records the physical location of the line and the depth of the surface, tells the plumber where the blockage is and what work needs to be done to fix it.
Sewer inspection cameras can identify almost all problems with your sewer, but these are some of the most common:
- Tree root infiltrations: This is most common with old pipes made of clay, cast iron, or other porous materials. Tree roots look for water sources as they grow, and if they find a gap in your drain pipe, they will grow into it to get to the water inside.
- Broken, cracked, or collapsed pipes: Because the camera feeds along the pipe itself, the plumber will be able to find out whether the pipe has collapsed, shifted, or damaged.
- Major blockages: Sometimes your pipe is in perfect condition, but for years sending goods to pipes that have to be disposed of in the trash has caused a buildup of oil, paper, and other impurities.
- Sagging or bellied sewer lines: When a part of the sewer pipe starts to loosen, the waste is trapped in the leveled part - which results in repeated blockages.
After the plumber identifies the cause of the sewer backup, you may have different options to overcome the problem.
If a sewer camera inspection shows that your sewer line is loose, swollen, or collapsing, traditional repairs will be your only choice. Pipeline companies will dig trenches on your property to uncover drains and repair or replace pipes that cause problems. This method can cause damage to other parts of your property (concrete paths and entrances, landscaping, etc.) But, unfortunately, this is the best choice in some cases.
The method of repairing trench sewers is far less invasive and destructive than traditional trench excavations. A trench without a ditch begins with making a small access point to the damaged pipe. A cable is inserted and pulled, following the existing lane, while simultaneously pulling the replacement line to its position.
