Broken drain pipes can cause sewer gasses to seep into the interior or exterior of your home if the pipe that's broken is in the yard. Apart from broken pipes, clogged pipes can result in this smell as well. If you suspect this is the reason behind the sulfur smell, contact your nearest plumber.
Mercaptan gives off a strong sulphur-like smell which can be mistaken for the smell of rotten eggs. It's often this smell that is the early warning of any sort of gas leak and you should take the appropriate measures to ensure the safety of yourself and others around you.
If you do notice that "rotten egg" smell and suspect a natural gas leak, do not try to find the source of the leak yourself, but leave the building or area and call the 24-hour emergency Peoples number at 1-800-400-4271, or call your local emergency response number.
Yes, a smell of rotten eggs is a sign of a natural gas leak.
Rotten Eggs
The two most common sources of a rotten egg smell are a natural gas leak, and escaping sewer gas. In its natural state, natural gas is actually odorless. That's why utility companies inject a substance called mercaptan, which emits an odor that smells like sulfur or rotten eggs.
The first thing is to make sure the smell is sewer gas which is usually a rotten egg smell and not a natural gas smell which usually smells like a skunk.
Radon gas has no colour, smell or taste and is completely imperceptible to humans, even in high concentrations. Radon occurs naturally in the rocks and soil beneath us, but there is no way of knowing how much is escaping from the ground and entering a building.
Sewer gas produces a very distinct rotten egg smell, caused when organic materials break down and decompose to form hydrogen sulfide. If you're unsure about the smell coming from your drains or sewers, call a licensed plumber who can perform an inspection or clear and clean blockages.
Answer From Jonathan Graff-Radford, M.D. An olfactory hallucination, known as phantosmia, makes you detect smells that aren't in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant.
One often not considered source of a “gas-like” smell that can come from your home is bacteria inside of your sink or sewer system. It has a similar smell to the sulfur that is added to gas to give it an odor but is obviously less dangerous.
Carbon monoxide gas is odorless—it cannot be smelled. Some myths surround ways to detect carbon monoxide, such as identifying the strong scent of rotten eggs. However, never ignore the “rotten egg” smell of natural gas.
Chlorine bleach can effectively remove medium to high levels (over 6 mg/l) of hydrogen sulfide. The chlorine in the bleach chemically reacts with (oxi- dizes) the hydrogen sulfide eliminating the "rotten egg" odor. Chlorine bleach also reacts with iron or manganese, and disinfects water supplies.
'Leave a bowl of vinegar out overnight,' advises Saskia Gregson-Williams, Founder of Naturally Sassy. 'In the morning, the vinegar will have absorbed all the unsavory smells, and your kitchen will be as fresh as a daisy.
Some of the hardest and worst smells to get rid of are pet odours, mold, and cigarette smells.
The smell of sewer gas is often described as a noxious, rotten-egg-like odor. Its sulfuric, foul smell will permeate your entire home if left unaddressed, leading to major health issues down the line. Small amounts of sewer gas usually won't cause any immediate danger—but large amounts certainly will.
Any home can have a radon problem. This means new and old homes, well- sealed and drafty homes, and homes with or without basements. In fact, you and your family are most likely to get your greatest radiation exposure at home. That is where you spend most of your time.
Some people describe this smell as similar to acetone, nail polish remover, or even chloroform. The odor may become stronger with larger leaks, but it's often subtle enough to go unnoticed. If you notice an unusual sweet or chemical-like scent near your HVAC unit or air vents, it could be a sign of a refrigerant leak.
If you smell rotten eggs in the home, call the gas company to make sure you don't have a gas leak. If there is no gas leak in the home, you may have a problem with your electrical system. If you smell the rotten egg smell near an outlet, that's probably where it is coming from.
Hydrogen Sulfide
The gas has a strong scent of rotten eggs, which makes it distinct from other, similar gases. If you detect this rotten egg scent and you are using hydrogen sulfide at your facility, this could be evidence of a leak.
The best way to determine the source of the leak is to perform a smoke test. This is done with equipment designed specifically for performing this test and uses inert smoke that is induced into the drain and vent system through a vent or a sewer cleanout.
