How to Clear Main Sewer Line

Although a clog in your main sewer line might seem like a little problem, there are numerous problems associated with clogged sewer lines. Backed up sinks and toilet draining into the tub are just some of the problems you may experience. Therefore, you need to clear the main sewer immediately.


Signs of a Clogged Sewer Line

You are required to watch out for these signs so that you can fix the problem before it becomes an emergency. There are certain signs that you need to look out for to determine whether you will hire a professional or do it yourself depending on how serious the problem is.

When you have several plumbing fixtures clogged at the same time. For example, if your toilet, bathtub, kitchen sink and your shower have backed up, there is a high probability that your sewer line has clogged. You need to understand that your toilet has a direct line to the main sewer line. Therefore, when it blocks or starts to back up, your sewer line has clogged, and it should be fixed immediately. 

On the other hand, if your toilet is working fine and all the other fixtures have backed up, or they are slowly draining, you might not have a clogged main sewer line

If your toilet bubbles when you run water into your sink.The bubbling of the toilet is as a result of trapped air in the plumbing system. This means that there is a clog and you need to have it fixed. If you are not sure whether there is a clog, you can run some water in the sink that’s closest to the toilet to see if the water level in the toilet rises or if there is bubbling. If any of the two happens, you have a clog.

If your toilet overflows or water backs up into the shower or your tubafter draining your washing machine, you have a main sewer line clog. However, if your toilet is flushing fine, you do not have any clog. This means that you might have plumbing problems related to the main sewer line and not a clog.

There are a number of things that can make your sewer line block beside having solid substances running through the sewers. For instance, tree and shrub roots in your yard can cause clogging when their roots bore through the sewer line. This kind of clogging cannot be fixed by the normal drain methods. Instead, you may have to replace the pipes, and this can only be done by a professional plumber.

Plumbing pipes that have shifted over time or the pipes that have not been installed properly can be prone to clogging. Therefore, ensure you hire an experienced plumber when repairing or replacing your plumbing pipes to avoid such related problems.
