Nobody wants to wake up to an overflowing toilet and discover that the plumbing system has been compromised.

You should know that simple items can lead to major clogs in the pipeline, and preventing them from making their way into the sewer line is important. If left untreated, semi-clogged pipes can become fully clogged, and you may have to change the entire pipeline.

Clogs are prevalent and can happen in any household, but the first sign of a clog in sewer lines is slow water movement. Check if the water is flowing down the sink or if it’s gurgling and pooling near the opening.

In such cases, call for a professional plumbing company to inspect the entire line immediately. If you are proactive, it might be possible to protect the pipes from large-scale damage.

Read on to learn about the common reasons that can cause clogging in sewer lines.

What Causes A Sewer Line To Clog?

1. Foreign Particles

Some common foreign particles that clog drains are diapers, tampons, pads, and other objects that you should not flush down the toilet. These do not dissolve in water and can lead to significant clogs, so you will need professionals to clean the entire pipeline. This becomes quite a task and can be expensive in some cases.

2. Fat, Grease, And Oil

Fat, oil, and grease may be in liquid form, but they can harden and stick inside drain pipes. Solid grease can cause a huge blockage, and you may need to change the pipes if needed.

To prevent this from happening, start using a grease trap for sinks. This rectangular piece of equipment is attached to the sink and ensures all the grease is collected. You can then dispose of the grease in the dustbin.

3. Tree Roots

One of the major causes of clogged sewer lines is tree roots, especially if you have a garden beside the house. If the tree roots are strong and thick, they can break into sewer pipes and create rot balls. These block the line completely, preventing any water or sewage movement.

Also, thin roots may tangle around the drain pipes and crush them completely. To prevent this, you will have to use chemicals in those areas to kill the roots. However, be careful and do not apply the chemicals repeatedly, as this can kill the entire tree.

Another way of tackling the issue is by removing plantations above the sewer lines to keep the plumbing system and surrounding vegetation safe.

4. Bad Or Malfunctioning Plumbing Connections

If you had not hired a skilled professional to install your plumbing line, you might have poorly assembled the plumbing connections. This can also lead to blockage inside pipes and leakage occurring underground. To prevent such a situation, you should always get experienced and licensed plumbers to handle the plumbing.

They will have strict policies, which means you will get the best services.

5. Old Sewer Pipes

If you live in a very old house, the sewer lines may have cracks and collapse or break easily, leading to large-scale plumbing issues. So, it is essential to get the pipelines checked once in a while and conduct a thorough inspection of the plumbing system if you are purchasing an old house.

This will help detect cracks for timely repairs and save you a lot of money.

Frequently Asked Questions

1. How to take care of the sewer line at home regularly?

You can use hot water to clear small-scale blockages in sinks, as it melts grease or fat stuck to the pipe walls. These will flow down the pipelines with the water to free up the sewer line. So, we recommend pouring hot water every once in a while, preferably twice or thrice a week.

2. How to understand if a sewer pipe has clogged up?

If you see water backing up when using water fixtures around the house, that could mean a blocked sewer pipe. This can happen when you flush the toilet, clear the bathtub or run the washing machine and notice restricted water movement.
