How To Spot Main Sewer Line Obstruction

Your home’s plumbing system relies heavily on the proper functioning of the sewer line, and any damage or obstruction in it can lead to unwelcome problems on your property. Repairing or replacing damaged or offset pipes can be a costly endeavor. Detecting a breakage or blockage in your sewer line early can save you from significant inconvenience and expenses. It’s important to note that damage tends to worsen with time.

Signs of a Sewer Line Blockage

Keep an eye out for these signs that may suggest a blockage in your main sewer line:

Slowly Draining Sinks and Bathtubs

1. When your sewer line is compromised, you might notice that sinks, toilets, and bathtubs drain slowly or become completely clogged. This issue can affect multiple fixtures in your home. For example, if using the washing machine causes the toilet to overflow or the laundry room sink to back up, it’s a clear indicator of a blockage somewhere in the drainpipes, as the water must find an alternate path.

Additionally, if you hear gurgling sounds when you flush, it could be a sign of a blockage within the drain system. These noises may also hint at tree roots causing the blockage, as root systems are a common culprit in main sewer line problems. If you have a large tree near your sewer line, its roots may be the cause, especially if your sewer is older and made of clay or concrete, as roots can infiltrate through pipe joints. These tiny feeder roots seek moisture and can grow, forming a barrier that catches toilet paper and waste, leading to a clog.

Frequent Plunging Needed

An increase in toilet clogs or more frequent clogging of your kitchen sink can indicate that the real issue lies further down in your drainage system. If you have multiple slow drains in your home, it’s a strong indication that a clogged sewer is the source of the problem.

Common Sewer Line Issues

The sewer line is the largest drainage component in your home, and it can be vulnerable to various problems. The most common issues affecting a sewer line include:

• Tree roots: Infiltrating roots can quickly damage a sewer line.
• Broken, collapsed, cracked, or misaligned pipes: These issues often result from shifting soil or frozen ground.
• Blockage: Grease or foreign objects can obstruct proper water flow.
• Pipe corrosion or deterioration: Older or non-PVC pipes are at risk of deterioration, leading to pipe collapses and reduced flow.
• Bellied pipe: Sections of the pipe sinking into the ground, creating areas for waste to accumulate.
• Leaking joints: Broken seals between pipes can lead to water leakage into the surrounding area.

Preventative Measures

It’s essential to remain vigilant and proactive in identifying signs of blockage and preventing future problems. Schedule septic tank inspections every three to five years to allow experienced professionals to check for breaks or cracks. Timely inspections often lead to minor repairs that can prevent expensive replacements.

Cleaning out the sewer line or performing spot repairs can usually resolve the problem. However, if the issue is advanced, a costly replacement may be necessary. Your technician may conduct a camera inspection to identify the source of the problem and discuss service options with you.

Is Replacement Cost-Effective?

In certain cases, replacing the sewer line can be a more cost-effective solution than attempting repairs. If your pipes are made of inferior materials, they are more prone to leaks, damage, and root intrusion, which can lead to more substantial problems down the line, surpassing the cost of the initial replacement.
