What Sewer Gas Smells Mean (And Why You Shouldn’t Ignore Them)
Homeowners often describe sewer gas as smelling like rotten eggs, sulfur, or a musty decay that seems to linger near bathrooms or laundry rooms. These odors aren’t just unpleasant—they’re a warning sign that harmful gases are escaping your plumbing system. While a brief smell after a drain dries out can be harmless, repeated or persistent odors usually point to an underlying leak or venting issue that needs professional attention.
Common Causes of Sewer Gas Leaks in Monrovia Homes
Many Monrovia homes—especially older properties—experience sewer gas leaks due to dry or improperly installed P-traps, cracked sewer pipes, or damaged vent stacks. Aging plumbing materials, soil movement, and tree root intrusion common in tree-lined neighborhoods can all compromise sewer lines. Poorly sealed toilets and shifted drain connections are also frequent culprits we uncover during inspections.
Is Sewer Gas Dangerous? Health & Safety Concerns
Yes—sewer gas can be dangerous. Short-term exposure may cause headaches, nausea, dizziness, and irritation, while long-term exposure can impact respiratory health. Methane, a common component of sewer gas, is also flammable, which creates a serious fire or explosion risk in enclosed spaces. Fast detection is critical for protecting your family, pets, and indoor air quality.
How Professional Sewer Gas Leak Detection Works
Diagnostic Methods Used by Local Experts
Professional sewer gas leak detection relies on advanced diagnostic tools—not guesswork. Local plumbers use smoke testing to reveal hidden leaks, sewer camera inspections to assess pipe conditions, and odor tracing to pinpoint problem areas. Ventilation systems are also evaluated to ensure gases are properly released outside, not into your home.
Why DIY Odor Fixes Often Fail
DIY fixes often mask odors rather than solve the underlying problem. Without proper equipment, it’s easy to misdiagnose the issue—leading to recurring smells and potential safety risks. Professional detection ensures the root cause is addressed the first time.
Sewer Odor Problems Specific to Monrovia, CA
Monrovia’s older homes, slab foundations, and mature trees create unique plumbing challenges. Sewer lines may shift due to soil movement, while roots can invade aging pipes. Seasonal heat common in the San Gabriel Valley intensifies sewer gas odors, making minor leaks suddenly noticeable. Local code requirements also play a role in how vents and drains must be repaired.
Signs You Need Sewer Gas Leak Detection Now

Sewer Gas Leak Repair Options After Detection
Once detected, repairs may include refilling or replacing traps, resealing toilets, repairing vent pipes, or addressing damaged sewer lines. In some cases, trenchless repair options allow fixes with minimal disruption to your property. Preventive maintenance recommendations help reduce the chance of future leaks.
