Causes and Signs of Main Sewer Line Blockages
There are several important plumbing fixtures, drains and pipes in your home, and each of them has at least one thing in common: They’re all connected in some way to the main sewer line. This line, one of the most important plumbing-related areas in any home, generally extends out into the yard and connects your system to the primary water supply in your area while also performing several other vital tasks.
At JMBP Plumbing, we offer a wide range of services for your main water line, including vital replacements anytime something goes wrong. Clogs and other blockages in this area are particularly damaging due to how central this system is for all your plumbing needs – let’s go over some of the common causes of main sewer line clogs that you need to avoid, plus some signs that your main line might be having issues you should have inspected by our plumbers.
Causes of Main Sewer Line Clogs
- Major pipe damage: Whether due to corrosion, shifting soil that changes the placement of pipes, leaking joints due to individual areas of damage, or even construction taking place above the area, broken or ruptured sewer pipes are the chief cause of main plumbing line blockages.
- Tree roots: As we noted above, main sewer lines run through part of the yard on most properties. In cases of older lines, those made from clay or other porous materials, tree or shrub roots nearby will grow into the pipe to try and siphon off the water inside. These roots will only expand and create further issues with time.
- Sagging line: In other cases, sagging sewer lines may take place when a section of pipe sinks into the ground or settles into soil. This isn’t always something you can control, but the low spot will begin to pool up with waste that eventually blocks the entire system.
- Improper drain usage: Finally, flushing impermissible items down the drain, whether toilet or otherwise, can create main sewer line issues. This includes not only any debris, such as trash or anything besides approved toilet paper, but also grease, oil and other fat types you might be tempted to pour down the sink drain.
Red Flags for Sewer Line Problems
Here are some warning signs that your main sewer line has an issue building up:
- Common backups: An occasional backup in one of your drains doesn’t necessarily mean the water line is compromised, but regular such backups in multiple drain areas is a red flag.
- Other fixture issues: Have you noticed water backs up in the tub or shower when you flush the toilet? What about if your toilet water begins to bubble when you turn on the bath? Any such issue of strange reactions when using fixtures could signal a main water line problem.
- Lawn issues: Once again, your lawn could showcase some of your sewer line issues. If you notice an indentation on the grass, or a soggy patch of grass despite no recent precipitation, this is often due to a broken pipe in the main sewer line.
