A sewer gas smell in your home is more than unpleasant—it can be a sign of underlying plumbing issues that need immediate attention. At Polar in Belleville, IL, we understand how vital it is to maintain a safe and odor-free home. Sewer gas contains a mixture of harmful gases, including methane and hydrogen sulfide, which can pose health risks and impact indoor air quality. Knowing the common causes of sewer gas odors and when to call for professional help can save you from further damage and costly repairs.
Dry P-Traps
P-traps are the U-shaped pipes beneath sinks, tubs, and other drains that hold water to block sewer gases from entering your home. If a P-trap dries out due to infrequent use, it loses its seal, allowing odors to escape. You’ll often notice this in guest bathrooms or unused drains. A quick fix involves running water down the drain to refill the trap, but persistent smells might indicate deeper issues. Call Polar if the smell doesn’t disappear or recurs, as we can inspect and repair the problem efficiently with sewer cleaning or jetting services.
Cracked Sewer Pipes
Cracked or damaged sewer pipes can leak harmful gases into your home. Over time, pipes may corrode or crack due to age, shifting soil, or improper installation. Signs of a damaged pipe include a persistent sewer smell, slow drains, or water damage in your home. Repairs require expertise, as locating and fixing the issue often involves specialized tools and techniques. Polar’s experienced plumbers can diagnose the issue and replace damaged pipes to restore your system’s integrity.
Clogged Drains
A clogged drain can trap organic materials like food, grease, or hair, creating a breeding ground for bacteria. As bacteria break down these materials, foul-smelling gases can rise through the drain. If your attempts to clear the clog with a plunger or drain cleaner fail, it’s time to call Polar. Our team uses advanced equipment to remove clogs safely and prevent recurring issues, protecting your plumbing and keeping odors at bay.
Broken or Missing Cleanout Plugs
Cleanout plugs are essential components that prevent sewer gases from escaping through the cleanout pipe. If a plug is broken, loose, or missing, you may notice a sewer smell near the cleanout access point. Inspecting and replacing cleanout plugs can be tricky, especially if the issue lies deep within the system. Polar’s professionals can quickly locate the problem and install a secure, durable replacement plug to eliminate odors.
Ventilation Problems
Plumbing systems rely on vent pipes to release sewer gases outside the home safely. If a vent pipe is blocked or improperly installed, gases can accumulate and enter your living space. This often happens due to debris, bird nests, or even ice buildup in the vent. Signs of ventilation issues include gurgling drains or toilets and persistent sewer odors. At Polar, we can inspect and clear your vents to restore proper airflow and eliminate unpleasant smells.
Sewer Line Backups
A sewer line backup occurs when wastewater cannot flow freely to the main sewer, often due to blockages from tree roots, grease, or other debris. This can cause sewage to back up into your home, leading to a strong sewer odor and visible water damage. Backups require immediate attention to prevent health hazards and costly repairs. Polar’s skilled technicians can identify the cause of the blockage and use specialized equipment to clear the line, restoring your system’s functionality.
Faulty Wax Ring on Toilets
The wax ring beneath your toilet creates a seal between the toilet base and the drainpipe. If this ring becomes damaged or improperly installed, it can allow sewer gases to escape. You may notice a smell around the base of the toilet, or the toilet may wobble when used. Replacing a wax ring requires removing the toilet, which can be a challenging DIY task. Trust Polar to handle the job efficiently, ensuring a secure seal and eliminating odors.
Septic System Issues
Homes with septic systems may experience sewer odors due to an overloaded or malfunctioning tank. If the tank is full or improperly vented, gases can escape and seep into your home or yard. Other signs of septic problems include slow drains, standing water near the tank, or lush patches of grass over the drain field. Addressing septic issues requires professional expertise, and Polar’s experienced team can inspect, pump, and repair your system to restore proper function.
When to Call for Help
While minor issues like dry P-traps can be resolved with simple fixes, persistent sewer odors or signs of plumbing damage require professional attention. Sewer gas exposure can cause health problems, including headaches, dizziness, and respiratory irritation. If you notice recurring smells, water damage, or multiple slow drains, it’s time to call Polar.
