Got a Bad Smell in Your Home? It Could Be Your Sewer
At Polar Plumbing, Heating, & Air Conditioning, one of the most common questions we receive from homeowners in O’Fallon, IL, is: “Why does my house smell like a sewer?” The answer is usually simple — your sewer system needs attention. Unpleasant sewer odors from drains, bathrooms, or basements are more than just a nuisance; they can be a health hazard. They’re often a warning sign that something’s wrong with your plumbing or sewer lines. In this post, I’ll explain what causes sewer odors and how proper sewer maintenance can help you eliminate them for good.
What Causes Sewer Odors in Homes?
Dry P-Traps
The P-trap is the curved pipe under your sink or drain. It holds water that acts as a barrier to prevent sewer gases from entering your home.
When drains aren’t used regularly — such as in guest bathrooms or basement showers — the water can evaporate, allowing unpleasant smells to permeate.
Damaged or Cracked Sewer Pipes
Cracks in underground pipes can leak gas into your home or yard. You may notice:
- Odors near foundation vents
- Patches of lush grass (from leaking sewage)
- Persistent smells inside even after cleaning the drains
Why Sewer Odors Shouldn’t Be Ignored
Sewer gas isn’t just unpleasant — it can be dangerous. Prolonged exposure to hydrogen sulfide can cause:
- Headaches
- Nausea
- Fatigue
- Irritation of the eyes and throat
Even small leaks can compromise your indoor air quality and indicate serious issues in your plumbing system.
How Polar Plumbing Solves Sewer Odor Problems
We specialize in residential sewer maintenance and odor elimination throughout O’Fallon IL. Our proven approach includes:
Step 1 — Sewer Camera Inspection
We begin with a video sewer inspection to locate:
- Blockages
- Cracks
- Tree root intrusion
- Pipe misalignment
This provides us with a comprehensive understanding of your system, enabling us to recommend the most suitable solution.
Step 2 — Sewer Line Cleaning
We use hydro jetting to clear buildup and remove clogs deep in your sewer lines. It’s powerful, safe for your pipes, and highly effective at removing grease, soap scum, and debris.
Step 3 — Repair or Replace Damaged Sections
If we discover broken or deteriorating pipes, we provide expert sewer repair and pipe replacement using either trenchless or traditional methods, depending on what is best for your home.
Step 4 — Trap & Vent System Checks
We also inspect your home’s P-traps and venting system to ensure that gases are being safely redirected out of your home and that drains are properly sealed.
Sewer Maintenance Tips to Prevent Odors
You can help keep your sewer system in good shape year-round by following these tips:
Run Water in Infrequently Used Drains
Once a week, run water in basement floor drains, guest bathroom sinks, or unused showers to keep P-traps full
Avoid Chemical Drain Cleaners
Harsh chemicals can erode pipes and damage traps. Instead, use enzyme-based cleaners or hire a professional for drain cleaning.
Watch for Early Signs
Don’t ignore:
- Gurgling noises
- Bubbles in the toilet
- Odors after storms
These may signal a potential sewer problem lurking beneath the surface.
Schedule Annual Sewer Maintenance
Annual inspections and cleaning can catch issues before they become emergencies. It’s especially important if your home is:
- Over 20 years old
- Surrounded by large trees
- On a septic-to-sewer conversion
