Sewer odors can be quite bothersome, and breathing around a toxic sewer smell may take a toll on your physical and mental health.

If you don’t want to live with such nasty odors, learn about what you can do about it.

Most Common Sources of Sewer Odors

Plumbing fixtures, including but not limited to sinks, showers, drains, and toilets, are all a part of a larger network and make up a home’s drainage system, which also includes drain pipes, traps, and vents. The whole system is designed to carry wastewater to the public sewer and prevent sewer gasses from getting inside your home.

So, if you smell a sewer odor, it indicates there’s a weak link in your home’s plumbing. Most common places where a sewer odor may emerge include kitchen drains, bathroom sinks, toilets, basement drains, vent stacks, or old cast iron piping areas.

Common Causes

Insufficient Vent Pipes or Drain Traps

P-traps are highly effective in holding water in a ‘’U’’ shape. They create a seal that equalizes air pressure and facilitates the seamless movement and removal of sewer gases.

Dry Traps

This problem typically arises in drains that aren’t used regularly, such as guest bathroom faucets and showers, and basement drains.

Broken Seals

Whether you’re trying to fix your home’s plumbing issues yourself, or hiring a professional plumber to resolve them, don’t forget to check if there are any broken seals in your bathrooms. Always inspect carefully to see if gas or air is leaking somewhere. Ensure that the toilet bowl is sealed tightly to the flooring.


Clogging can also cause a notorious smell to spread throughout your home. Consider hiring a professional plumbing company to identify if any vent stack is clogged and get it fixed if they find one.

Cracked Pipes

If there are any old cast iron pipes in your home’s plumbing system, consider getting them replaced with the new, high-quality PVC piping. It’s because old cast iron pipes can easily crack and cause gas leakages.
