What can cause a Sewer Smell?
Your plumbing system was made to efficiently and safely move Water waste and sewer gases out of your home. When it does work as intended, you should not be able to smell anything “bad” in your house.
Odors from sewer systems are created by disruptions to the normal function of your plumbing system. Commonly cited reasons why you might experience sewer odors include:
• drain lines with dry p-traps
• clogged drain lines
• blocked plumbing vents
• damaged sewer lines
• bad connections between loose or broken piping
• crack(s) in Toilet seal(s)
• sewer line backs-ups
Some are going to be easier to correct than others. However, in order to correct the majority of them, you will likely need a professional diagnosis and/or repair.
Could your dry p-trap be causing the stink?
Each sink, each shower/bathtub, and each floor drain has a p-trap. P-traps are curved sections of pipe that hold a little bit of Water. This Water serves as a protective barrier between your house and the rest of your sewer system.
Once enough time passes after you last ran Water down the affected drain, the Water inside the p-trap evaporates. Sewer gases can then flow into your house and cause an unpleasant odor.
However, fixing a dry p-trap is One of the simplest plumbing issues you’ll ever face. All you generally need to do is run Water down the affected drain for a couple of seconds. This will refill the p-trap and get rid of the stinky smell.
Are clogged drains creating unpleasant odors?
In addition to grease, hair and food particles accumulate in kitchen and bath drain lines.
As this accumulation breaks down, unpleasant smells are produced. Homeowners commonly mistakenly think this smell comes from sewer gases because they believe that the smell comes from somewhere underground in their sewers.
Although running Water through the drain after cleaning it may temporarily eliminate the odor, the blockage could be farther down in the plumbing system if the smell returns. An experienced plumber can use special equipment to determine exactly where the clog lies in your plumbing system and safely remove any build-up without damaging any pipes.
If leaves etc. Block your sewer vents, that creates opportunities for sewer gases to enter your house!
Your home’s plumbing vent system is responsible for allowing sewer gases to safely exit your home via vents installed in your roof.
If debris (leaves etc.) obstructs your plumbing vent(s), it’s possible that sewer gases won’t escape properly. These gases can instead back up into your home through nearby drains.
Since plumbing vents are normally found on your roof, diagnosing and clearing clogs associated with plumbing vents is best done by an expert plumber.
Do you have a leaking wax ring underneath your Toilet?
Sometimes, the problem isn’t just inside the drain itself.
Leaks from sewer gas occurring around the base of your Toilet could be due to a faulty wax ring under your Toilet. You may notice that the odor is especially strong in One bathroom or near your Toilet itself.
Other indicators of a bad wax ring include:
• Water accumulating around the base
• a Toilet that moves/shifts when sat upon
• the odor remains present despite regular cleaning
Replacing the wax ring should eliminate the stinky smell and prevent future damage.
Is a Sewer Smell from your main sewer line damage?
Damage to the main sewer line is another cause of sewer odors that is more serious.
Causes of main sewer line damage include tree root invasion into your pipes, settling ground/sinking soil around pipes, corroded pipes, old pipes cracking or breaking apart, or blockages forming in your main sewer line.
Warning signs for potential main sewer line damage include:
• multiple slow-draining fixtures
• gurgling toilets
• sewage flowing backward into sinks/showers/tubs
• damp areas in your yard
• areas of unusual growth in your lawn (especially near drainage pipes).
• frequently clogging multiple drains within your home
These types of symptoms normally represent significant plumbing issues requiring inspections by licensed professionals.
Should i hire a reputable plumber?
Don’t wait until it becomes an emergency to take action on an ongoing Sewer Smell.
Every homeowner should seek assistance immediately if they encounter:
• odors persist longer than 1-2 days.
• odors originate from multiple drains.
• rinsing drains with Water no longer resolves odors.
• sewage is backing up into fixtures.
• multiple drains are clogged simultaneously.
• odors continue intensifying.
Professional plumbers use specialized equipment, including video-inspection tools and leak-detection technology. These tools allow them to quickly locate the origin of odors without tearing apart floors/walls etc.
Can exposure to sewer gas create health issues?
A temporary sewer odor from a dry drain is unlikely to create health-related risks. However, prolonged exposure to sewer gases may be indicative of a larger plumbing problem.
Sewer gases contain compounds that create foul odors and can negatively impact indoor air quality if left unaddressed.
Additionally, failure to promptly investigate ongoing sewer odors increases the likelihood that an undetectable leak/damage exists behind walls/subsurface areas.
Early detection provides protection for both your home and family members’ health.
How do you prevent sewer odors before they happen?
Routine maintenance on your plumbing system can greatly minimize the likelihood of experiencing unpleasant sewer odors.
Simple preventative measures include:
• Run Water down unused drains periodically (every week or 2).
• Don’t pour grease down kitchen drains.
• Don’t put sanitary wipes/hygiene products down commodes/toilets.
• Arrange for periodic drain cleaning based on usage.
• Have your main sewer line inspected if you reside in an older home.
• Tackle slow draining drains prior to them causing severe clogs.
Preventing plumbing failures resulting from neglectful maintenance will cost significantly less money than addressing expensive repairs required as a result of catastrophic failures later on.
