How do you fix smelly sewage?
If your home smells like rotten eggs or moldy drains, you’re not alone. At some point, nearly every homeowner will ask: How do you fix smelly sewage? This problem is not only unpleasant—it can signal serious plumbing issues. Whether you’re in Florida looking for south tampa plumbers or in Arizona seeking affordable plumbing in Tucson, this guide is for you.
Let’s break down the common causes, effective fixes, and where in California this issue tends to pop up most.
Common Causes of Smelly Sewage in Homes
Sewer odors can come from various sources. Understanding the root cause helps in applying the right solution:
1. Dry P-Traps
A dry P-trap is the most common culprit. This U-shaped pipe is supposed to hold water to block sewer gases. If it dries out, the gases escape back into your home.
2. Clogged or Dirty Drains
Hair, grease, and debris buildup in drains can create an ideal breeding ground for bacteria. The result? Nasty smells.
3. Cracked Sewer Pipes
Old or broken sewer lines can release gas and moisture under your foundation or into your yard.
4. Blocked Vent Pipes
Your plumbing vent system removes sewer gases from your home. If it’s blocked, those gases might come back through your drains.
5. Septic Tank Issues
Homes using septic systems may deal with odors if the tank is full or has drainage issues.
Fixing Smelly Sewage: Step-by-Step
Let’s look at what you or a professional plumber can do to fix the issue.
1. Run Water Through Drains
If you have a rarely used sink or shower, try running water for a minute or two. This will refill the P-trap and may stop the odor.
2. Clean Your Drains
Use a mixture of baking soda and vinegar followed by boiling water. This flushes out minor buildup and neutralizes smells.
3. Inspect for Cracks or Leaks
This is where South Tampa plumbers and affordable plumbing in Tucson really shine. Using a camera inspection, they can find cracks in sewer lines fast.
4. Clear Vent Pipes
Use a plumber’s snake to check and clear the vent stack. Blockages could be anything from leaves to dead rodents.
5. Pump the Septic Tank
If you’re on a septic system, hire a local plumber to pump the tank. Foul odors are often the first sign it’s time for maintenance.
Cities in California Where This Issue Is Common
Smelly sewage problems are especially common in older homes and regions with aging infrastructure. Based on plumbing reports and repair trends, here are California cities where this issue is frequently reported:
- Los Angeles – Due to older sewer lines and population density
- San Diego – Coastal corrosion and aging systems
- Fresno – Dry climate causes P-traps to dry out faster
- Sacramento – Frequent venting problems in older homes
- Bakersfield – High mineral content affects plumbing seals
If you’re in any of these cities and noticing foul odors, call a licensed plumber immediately.
Why You Need a Professional
Some fixes are DIY-friendly, but others need expert attention. Sewer gases contain methane and hydrogen sulfide—both hazardous to your health. Hiring local specialists like South Tampa plumbers or affordable plumbing in tucson ensures the job is done safely and thoroughly.
What Pros Can Do:
- Perform smoke tests to locate leaks
- Use hydro-jetting to clear clogs
- Replace old pipes and seals

Fixing smelly sewage is one thing. Keeping it from coming back? That’s another.

- Have your sewer line inspected annually
- Pump your septic tank every 3–5 years

These habits can save you from future headaches—and unexpected plumbing bills.
