Common Causes of Sewage Backups and How to Address Them - Bio-One of South OC

Sewage backups are an issue that no one wants to deal with, and it's one that can happen to any property owner. There are many causes of sewage backups, from clogs to damaged pipes, and they can cause significant damage and health concerns if not handled quickly and efficiently. Fortunately, there are several solutions to address these common causes. In this post, we will discuss the main causes of sewage backups and provide some effective solutions that you can use to address them!


One of the most common causes of sewage backups is clogs. Clogs can occur anywhere in the pipes, from the drain to the main sewer line. Some common culprits include flushing items down the toilet that shouldn't be or pouring grease down the sink. Other causes include tree roots growing into the pipes and damaged pipes caused by age or wear and tear.

The first step to addressing clogs is identifying where they are located. In some cases, a plunger or drain snake may be all that is needed. For larger clogs or those deeper in the pipes, it may require professional assistance.

Damage to Pipes

Another common cause of sewage backups is damage to the pipes. Pipes can become damaged due to age, wear and tear, or external factors such as tree roots. If your property has older pipes, it's essential to have them inspected regularly to catch any potential issues before they become major problems. It's also important to avoid putting too much pressure on the pipes. Avoid flushing large amounts of toilet paper or pouring chemicals down the drain.

Heavy Rainfall

During heavy rainstorms, the sewer system can become overwhelmed and cause backups and overflows. The best way to address this issue is to install a backwater valve. This device is installed in the main sewer line and can prevent water from flowing back into your property during heavy rainfall.

Improper Installation

If your property has recently undergone a plumbing installation or renovation, it's possible that the new system was improperly installed. This can lead to leaks, clogs, and other issues that can cause sewage backups. It's essential to work with a reputable and experienced plumbing professional when installing new plumbing systems to avoid these issues!

No Maintenance

Finally, a lack of maintenance is a common cause of sewage backups. Regular inspections, cleaning, and maintenance of your plumbing system can help detect and address potential issues early on, preventing major problems down the line.
