When you have a clogged drain in your house, your first instinct is probably to grab a plunger. Little do you know, there are some cases where standard plunging is almost useless — like when the main sewer line in your home gets clogged. When this happens, you can end up with widespread flooding and plumbing problems all over your home.
Are Your Main Sewer Lines Clogged?
Throughout your home, you have drain lines carrying wastewater away from sinks, toilets, tubs and more. All of these lines lead to the main sewer line. This huge pipe sends all the waste from your home right to your sewer or septic system. When it gets clogged, drains all over your home are unable to work — and you could even end up with water backing up out of your fixtures, leaky pipes and other problems. Yikes!
If you find yourself with a main sewer line clog, there’s not really any do-it-yourself way of fixing it. These drain lines are often buried deep under the ground far away from your home. You typically need special equipment and professional know-how to handle them. Though you usually cannot repair it yourself, that doesn’t mean you’re helpless. There are still a couple things you can do to keep the problem from getting worse until a plumber can help you.
Clogged Sewer Line Causes
This type of clog is fairly rare, since most sewer lines are around 4 to 6 inches wide. It usually only happens if something has gone seriously wrong in your plumbing system. One of the most common causes of a clog is damage to the sewer line itself. If a pipe collapses or bends, the damage can keep waste from moving through the line properly. There are all sorts of things that can harm a sewer line, including:
- Shifting soil around the pipe
- Corrosion within the pipe
- Construction near the line
- Heavy traffic above the sewer pipe
- Damaged pipe joints
Another big reason sewer lines clog is that they gradually sag over time. This bend in the pipe makes it easy for debris to collect, eventually causing a clog.
The most common type of debris that clogs a sewer line is fat. If you pour greases, fats or oils down a sink drain, they will eventually cool and harden. Even if you run hot water with the grease, it typically firms up by the time it reaches your main sewer line. Then, the fat sticks to your lines and causes a clog.
Other types of debris that often causes clogs includes paper towels, so-called flushable wipes, sanitary products and other bulky items flushed down the toilet. You should never send anything besides liquids and toilet paper down your drains.
