A well-maintained sewer system is essential for any household. Issues with your sewer line can lead to costly repairs, health risks, and major disruptions to your daily life. By taking a few preventive measures, you can avoid these issues and maintain a smoothly running home in Snohomish County, King County, or Skagit County.
Preventing sewer line problems starts with understanding their common causes, such as tree roots, sediment buildup, and flushing inappropriate items (those ‘flushable wipes’).
When these signs appear, Elite Plumber & Sewer is ready to help you resolve the issue quickly, guaranteeing the safety and comfort of your home.
Key Takeaways
- Regular maintenance and mindful disposal prevent sewer line issues.
- Watch for early signs to avoid severe damage.
- Professional help is essential when issues arise.
Understanding the Common Causes of Sewer Line Issues

Tree Root Intrusion: Tree roots naturally seek out moisture, and your sewer line can be an attractive source. Over time, roots can find their way into small cracks in the pipes, causing significant blockages and damage. This can lead to slow draining water and even complete pipe collapse if not addressed promptly.
Pipe Corrosion: Aging pipes, especially those made from materials like cast iron or clay, can deteriorate over time. Corrosion weakens the pipe walls, leading to leaks, breaks, and blockages. If your home has older plumbing, it’s important to monitor for signs of corrosion and consider replacing outdated pipes.
Blockages from Debris: Flushing non-flushable items or pouring grease and fat down the drain can cause severe blockages in your sewer line. Items like wet wipes, paper towels, and hygiene products should never be flushed. Grease and fat solidify within the pipes, creating stubborn clogs that can be difficult to remove.
One house I moved into had roots growing into the main water line. It took three days of on and off Eeling (a much bigger version of the drain snake, needs a machine to maneuver it about) before I accidentally broke the base of the pipe. Nothing a good ole glob of PB weld couldn’t mold until I sold the home, though.
Preventive Tips for Maintaining a Healthy Sewer Line

Schedule Regular Inspections:
It’s important to schedule yearly inspections with a professional plumber, like Elite Plumber & Sewer. Regular checks can identify potential issues before they escalate.
Mind Your Landscaping:
Planting trees and shrubs too close to your sewer lines can cause problems. Tree roots can infiltrate and damage the pipes. Make sure you know where your sewer lines the root system of your plants that you plan on having before letting them take ‘root’ in your piping.
Practice Proper Waste Disposal:
Always dispose of waste correctly. Avoid putting grease, oils, wet wipes, or harsh chemicals down the drain. These items can cause buildup and blockages in the sewer line. Harsh chemicals can have adverse reactions within your pipe system, causing many problems.
Use a Grease Trap:
If you frequently use oils or grease in your kitchen, consider installing a grease trap. This device can capture grease before it enters your sewer system, reducing the risk of clogs.
Avoid Flushing Non-Degradable Items:
Only flush toilet paper and human waste. Items like sanitary products, diapers, and cotton balls should be thrown in the trash. These can cause severe blockages in the sewer line.
Monitor Water Pressure:
Excessive water pressure can strain your pipes. Use a pressure regulator to make sure that the water pressure in your home is at a safe level.
Use Enzyme Cleaners:
Regularly use enzyme-based cleaners to break down organic material in your pipes. These cleaners are safe and help keep your sewer lines clear from buildup. I have personally used enzyme cleaners in many restaurants. They are extremely helpful in mitigating odors and pests, as well as safely breaking down the blockages.
Install Backflow Valves:
Consider installing backflow valves to prevent sewage from backing up into your home. These valves are especially useful in areas prone to flooding. Every pipe system should have backflow safeguards, but if yours is lacking of them, do not hesitate to place them in.
Signs That Indicate Potential Sewer Line Problems

Slow Drains and Gurgling Noises: You may notice your sinks, bathtubs, or toilets draining slower than usual. This can be one of the first signs of blockages or root intrusion. Additionally, hearing gurgling noises can also be a warning sign that something is blocking the sewer line.
Frequent Backups: Experiencing backups often, particularly in the lowest drains of your home like the basement, is a strong indicator of a serious issue within your sewer line.

Unpleasant Odors: If you detect foul smells coming from your drains, it could mean your sewer line is either broken or blocked. These odors can be particularly strong and unpleasant, indicating that sewage is not being properly transported away from your home.
Lush Patches in Your Yard: Too-green or extra-lush patches of grass in your yard might be a sign that a sewer line has broken underground and is leaking wastewater, which acts as a fertilizer.
Wet Spots or Sinkholes: Unexplained wet spots or sinkholes in your yard can also indicate a damaged sewer line. Water leaking from the line can cause these problem areas to develop.
Mold and Mildew: Noticing mold or mildew growth around your home, especially in areas near plumbing fixtures or walls, might indicate a leaking or damaged sewer line. The excess moisture from leaks creates a favorable environment for mold and mildew to grow.
Toilet Water Level Fluctuations: If the water level in your toilet bowl seems unusually high or low, this can be another sign of sewer line problems. Pay attention to these fluctuations, as they can indicate underlying issues.
When to Seek Professional Help

Persistent Issues: If you’ve tried basic fixes, but sewer line problems keep coming back, it’s time to call a professional. Recurring problems can signal a larger issue that requires expert intervention.
Foul Odors: A persistent bad smell around your home can indicate sewer line issues. Professionals can locate the source and provide the best solution.
Slow Drains: If multiple drains in your home are slow, it might be more than a simple clog. Calling in an expert can help identify deeper problems in the sewer line.
Water Backups: Frequent backups in your sinks, toilets, or showers are clear signs of severe sewer line issues. Professional help can prevent these issues from causing significant damage.
