- Be aware that sewer gases can contain hazardous compounds such as methane, so if you smell anything similar around your bathroom pipes, turn off your gas supply immediately and get in a professional for urgent inspection and repair.
7 Causes of Sewer Smell & How to Fix Them
If you can pinpoint the cause of your sewer odor then you can likely fix it before it turns into a bigger and more costly issue. Whether you have a dried-out P-trap or a backed-up tank, you’re not alone in this smelly struggle, so let’s roll up those sleeves and solve this problem asap.
1. Dry P-Trap
If you’ve ever rummaged about in an under-sink cupboard you’ve probably come across the P-trap. This is the U-shaped drainage pipe connected to the underside of your sink. Water sits in the u-bend creating a water seal across the opening, crucial for keeping smelly gas from seeping into your home. All it takes to resolve a dry P-Trap is pouring some new water down the drain to rebuild that protective barrier – problem solved!
2. Damaged Toilet
If you have a sewage smell near your toilet this may be caused by a damaged wax ring, the seal that connects your toilet to the drainpipe. This may have happened due to improper installation or simply just due to wear and tear. A damaged wax ring can cause sewage gas to leak into your bathroom instead of being properly routed through the piping ventilation system. Replacing a damaged wax ring requires removing and reinstalling a toilet which we recommend getting done by a plumber.
3. Gurgling or Bubbling Gases
Gurgling sounds often indicate trapped water or air within either the sewer line or in a plumbing vent. This is most likely caused by some sort of blockage that will need to be vented out properly. If not, unpleasant sewer smells can escape through the drains and into bathrooms or kitchens.
4. Clogged Shower Drain
Clogged drains are a common culprit for odious odors in your bathroom since hair, soap scum, skin cells, etc., easily accumulate in pipes over time and create blockages. When not regularly removed, this can lead to wastewater backing up and results in that offensive odor.
To remove such clogs first detach the shower drain then pour down some boiling water, then add baking soda followed by vinegar, leave for 10 to 15 minutes, then finally run hot water for several minutes to flush out the loosened debris.
5. Clogged Plumbing Vent Pipe
Vent pipes, located on the roof of a home, allow for sewer gases to naturally escape from your plumbing and simultaneously prevent any air vacuums from forming inside the pipes. Such a vacuum if formed could cause wastewater backups into your bathroom.
This may be caused by random outdoor debris or nests being built inside vents resulting in blockages and bad smells filtering back into your home through toilet and sink drains. If this is the case, this can only be resolved by using specialized equipment designed for this purpose.
6. Bacteria Build-Up
Bacteria are present everywhere, including in your plumbing system. Here, they play an important role in breaking down organic material in your sewage system making it easier for other downstream treatments (e.g., septic tanks) to work more effectively. Nevertheless, when bacteria levels become too high due to an imbalance in their ecosystem it will lead to bad smells in your bathrooms.
For an obvious slimy orange-pink film on surfaces or in plug holes cleaning with some disinfectant or bleach will do the trick.
7. Sewer System Backups or Full Septic Tank
The most serious reason for a sewage smell in your bathroom is due to some kind of sewer backup or overflow occurring somewhere within your property’s underground pipelines. If it happens frequently, then you likely have an issue with either your primary sewer line or septic tank. Trust me when I say that this isn’t a job for a DIY enthusiast, you need a professional for this task ASAP. Act now and save yourself some serious trouble and cash!
When to Call a Professional Plumber
Some plumbing problems such as hair-clogged shower drains or dirty p-traps can easily be fixed with a little DIY know-how and some household tools. However, sanitary systems are complex, and trying to fix the problem yourself might end up costing you more than you bargained for in the long run. If after some troubleshooting the problem persists or worsens, it may be time to call in the experts. Here are some instances when calling a plumber is probably your best bet:
1. Multiple Clogs
If your home has multiple drains all clogged up at once, there is likely a wider root issue at play. A skilled plumber will have the specialized tools and equipment needed to diagnose the cause and fix it. So, sit back, relax, and leave this headache-inducing task to the pros!
2. Old Pipes
Old pipe systems are more prone to problems such as leaks simply due to wear and tear over time from the constant use of running water through them. If this is the case in your home call an experienced plumber who can help determine whether new piping installations are needed.
3. No Improvement With DIY Methods
If you’ve tried everything, but are still at a loss then it’s time to wave that white flag and get in touch with a professional.
4. Gas Leaks
Sewer gases in your bathroom pipes, particularly methane, can pose a serious health risk if significant amounts are inhaled over time. If you catch a whiff of gas-like odors emanating from your bathroom turn off your gas supply immediately and call out a pro asap for inspection and repair work.
5. Water Damage Or Flooding
We’ve all had nightmares of water damage or flooding wreaking havoc in our homes. If you have this issue you need a professional plumber, and you need them fast! They’ll have the expertise to survey the damage and identify any underlying structural flaws.
