If you are thinking about purchasing an older home, or if you have already done so, then it's important to make sure the main sewer line is in good condition. Failure to do so could result in a major sewage backup or a burst sewer line — both expensive problems to fix. The following are the main things your plumber will look for when performing a sewer line camera inspection.
1. Root Blockages
The most common issue with a main sewer line is tree root blockage. If there are any trees or large shrubs growing on or near the property, there is a high chance that some roots have invaded the sewer line. A camera inspection will locate any roots and help your plumber determine the extent of the problem. If caught early, roots can be removed with an auger and a drain treatment can be used to prevent future root growth. Then, subsequent treatments will ensure there are no further issues.
2. Developing Clogs
Any home can have a clog in the main sewer line, but older homes often have narrower sewer lines and have seen higher use. These two issues make the chances of a clog higher. A sewer line inspection will reveal any developing clogs, including their location and the main materials causing the clog. Your plumber can use this information to determine the best way to clear the clog. In some cases, the line itself could be causing clog formation, such as if it bends sharply. In this case, you can decide whether the old line should be replaced or if you should keep shopping for a different home.
3. Old Pipes
A home with an old sewer line isn't necessarily a problem, depending on the material used for the line and its state of repair. Some older lines are prone to leaks and breakage, especially old iron lines that have begun to rust through. Others will still have decades of life in them. A sewer line inspection allows your plumber to determine what type of material makes up the sewer line, which then helps the plumber provide you with the expected remaining lifespan of the old pipe.
4. Pipe Damage
Damage must be repaired promptly, but whether a repair or replacement will be necessary requires a full inspection. When you plumber performs the camera inspection they can pinpoint the exact location and severity of any damage. In some cases, you may only need to replace a short length of pipe, while in others a full line replacement may be necessary. The inspection will also show your options for replacement, such as whether the line is a good candidate for a trenchless replacement.
