When heavy rain hits Tacoma, it’s not uncommon for homeowners to notice strange smells, slow drains, or even backups in their plumbing. These problems often lead people to search for a trusted Tacoma sewer company that can inspect and fix the issue.
But why do sewer problems tend to show up more often after a storm? The answer is in how sewer systems work and how excess water can overwhelm them.
How Rain Impacts Sewer Systems
Sewer lines are designed to carry wastewater safely away from homes. When the ground becomes saturated after a storm, extra rainwater often finds its way into the sewer system. In some cases, old or damaged pipes allow groundwater to seep in. This extra flow can exceed the sewer’s capacity, causing backups or leaks.
Another common issue is surface runoff entering the sewer system. In areas with connected storm drains and sanitary sewers, large volumes of rainwater can overload the system. The excess pressure may push sewage back into homes through floor drains, sinks, or toilets.
Common Sewer Problems After Heavy Rain
Slow or Clogged Drains
One of the first signs of a sewer problem is slow drainage throughout the home. If multiple sinks, showers, or toilets start draining sluggishly at the same time, it could mean the main sewer line is struggling to handle the excess water.
Sewage Backups
Perhaps the most stressful issue is when wastewater backs up into tubs, sinks, or basements. This often happens when the sewer system is under too much pressure from heavy rainfall. A backup is more than just an inconvenience. It can cause water damage and pose health risks if not handled quickly.
Bad Odors
After a storm, you may notice foul smells coming from drains or your yard. These odors usually mean wastewater is not flowing properly and may be trapped in the system. This can also signal a hidden leak or crack in the sewer line.
Yard or Basement Flooding
If water is pooling in your yard or basement after rain, the sewer line may be leaking underground. This can lead to soft spots in the soil, foundation issues, and increased moisture problems inside the home.
Why Older Sewer Systems Are More Vulnerable
Many Tacoma neighborhoods have older sewer lines made from clay or cast iron. Over time, these materials can crack, corrode, or shift due to soil movement. Heavy rain makes these weaknesses worse. Tree roots are also more likely to invade aging pipes, seeking moisture and nutrients. Once roots grow inside the sewer line, they create blockages that trap debris and slow water flow.
Because older systems cannot handle the same pressure as newer ones, they are more prone to problems when the ground becomes saturated.
Why DIY Fixes Often Don’t Work
It can be tempting to try plungers, chemical cleaners, or small drain snakes when sewer problems arise. While these methods might provide temporary relief for minor clogs near a fixture, they rarely address deep or widespread issues in the main sewer line. Chemical cleaners can also damage older pipes and harm the environment.
When heavy rain is involved, the problem usually goes beyond a simple clog. A licensed Tacoma sewer company has the skills and equipment to locate the problem and carry out a reliable repair.
How Sewer Experts Fix Deep Blockages and Leaks
Sewer professionals use advanced methods to diagnose and repair deep blockages or leaks. Common techniques include:
- Sewer camera inspections: A small camera is fed into the line to pinpoint cracks, root intrusions, or blockages.
- Hydro jetting: High-pressure water is used to clear grease, roots, and buildup from pipe walls.
- Trenchless repairs: Modern techniques like pipe lining and pipe bursting let plumbers fix or replace pipes without tearing up your yard.
- Root removal: Specialized tools can cut through and clear roots that have invaded the system.
These steps not only fix the immediate problem but also help reduce the chance of it happening again.
How to Prevent Sewer Problems After Rain
You can’t stop the rain, but you can take precautions to protect your sewer system when storms hit:
- Avoid flushing items like wipes, paper towels, or grease that can make blockages worse.
- Keep gutters and downspouts clear so excess rainwater drains away from your foundation.
- Have older sewer lines inspected regularly, especially if your home is more than 40 years old.
- Schedule professional drain cleaning to remove buildup before it causes a backup.
Taking these precautions helps protect your home and keeps plumbing systems dependable through Tacoma’s rainiest months.
