The Main Causes of Sewer Backups

RTM Design • Mar 31, 2022

To say that sewer backups are a huge inconvenience would be an understatement. Not only are they smelly and off-putting, but they can also cause significant damage. It occurs when the wastewater from your home backs up into your drains and starts coming out of your sinks, toilets, and shower.

A sewer backup is not something that you want to experience, but in case it happens, you can rest easy knowing you can have it fixed by professionals at Trust 1 Services. From the top provider of quality sewer repair in Boston, MA, here are the main causes of sewer backups.

Tree Roots

One of the most common causes of sewer backups is tree roots. Trees love to grow near water sources–sewers included. Unfortunately, their roots can easily clog up the pipes. If you have a lot of trees near your home, you may have to deal with tree root intrusion down the line. The good news is this can be remedied with prompt sewer repair services.


Another common cause of sewer backups is blockages. This can be caused by anything from grease and fat to baby wipes and tampons. If you’re not careful about what you put down the drain, you may have clogging problems that can eventually lead to a backup. To avoid the need to replace sewer line sections because of severe pipe issues, be sure to dispose of cooking oils and fats properly. Dispose of tampons and wipes in the garbage can, not the toilet.

Cracked Sewer Lines

Sewer lines can crack for various reasons, including freezing temperatures, ground movement, and tree roots. If you think your sewer line might be cracked, it’s important to contact professionals for sewer line replacement as soon as possible to avoid a backup.


When it rains heavily, the rainwater can overwhelm the sewer system and cause a backup, thereby damaging the sewer line and warranting a sewer pipe line repair. This is especially common in older homes whose drainage systems aren’t well-maintained. If you live in an area that often experiences heavy rainfall, take steps to protect your home from water damage.

These are some of the most common causes of sewer backups. By being aware of them, you can take steps to prevent them from happening to you. If you experience a sewer backup in your home, contact us at Trust 1 services. We pride ourselves on quality services, value, and reliability!
