If you are detecting foul sewer odors inside the house, this means that there is a weak link somewhere in your plumbing system. Possible sources include bathroom sink drains, toilets, kitchen drains, basement drains, old cast iron piping, or even the vent stack that goes out through your roof.
When there is a broken seal – or the lack of a seal – in the caulk or wax ring around your toilet, it means water, urine and other waste find their way through the crevices, allowing bacteria to grow. This bacterium then causes the foul odor you detected. Luckily, the solution for this is fairly straightforward.
Caused by methane and bacteria, this odor in the winter months means something isn't right with your plumbing. Proper maintenance and inspection of all your plumbing will help keep the system in working order, and keep the odors at bay.
Pour a gallon of hot, boiling water down any drains that are rarely used, such as the basement drain or guest bathroom shower. This should help eliminate odors caused by dry traps.
In winter or dry climates, P-traps can evaporate in less than one month, so be sure to pour water into the drains or toilets every few weeks. If the smell is particularly bothersome, you can also add one cup of vinegar or bleach, which will also remove any insects that can enter the P-trap after it runs dry.
What is a P-trap? The P-trap is a crucial element of the home plumbing system. It is the U-shaped section of the pipe located underneath the sink. Its function is to trap and hold enough water, which acts as a barrier to prevent sewer gases and odors from making their way into the bathroom.
If you are noticing the smell of rotten eggs, it is possible that your water or sink drain is contaminated. It could also be that the drain is clogged or partially drained. When sinks are clogged, they drain slowly, which can cause bacteria to build up in the p-trap and create the hydrogen sulfide gas.
The principal risks and effects associated with exposure are: Hydrogen sulfide poisoning. Exposure to low levels of hydrogen sulfide causes irritation of the eyes and respiratory tract. Other symptoms include nervousness, dizziness, nausea, headache, and drowsiness.
Sewage smells are extremely unpleasant and can be caused by broken toilet seals, dry traps, cracked drain elements or a clogged vent system. Broken Toilet Seal: Check around your toilet, including near the u-bend. Any damage to the toilet seals could be allowing these pungent smells to escape into your property.
A clog in the drain line will create a buildup of organic matter like hair and soap. Bacteria will form on the clog, creating a nasty odor that resembles the smell of sewage. If left untreated, a clog will build on itself, growing larger and larger and producing more noticeable odors.
If you have, you may have experienced phantosmia – the medical name for a smell hallucination. Phantosmia odours are often foul; some people smell faeces or sewage, others describe smelling smoke or chemicals. These episodes can be sparked by a loud noise or change in the flow of air entering your nostrils.
because an empty or 'dried-out' P-trap is by far the most common cause of all sewer-gas smells. Each and every plumbing fixture and/or plumbing drain has a P-trap on the drain if it has been installed according to Code, and it's these P-traps that protect us from sewer-gas.
Smelling sewer in the home means there is an issue in the shower with the drain, a vent pipe that is cut or not installed properly on the toilet, or seals that are broken or loose. Finally, a build-up in the overflow of the sink can also cause this smell.
You may permanently damage your septic system. Bleach and cleaning fluids create toxic gasses when mixed together. If you pour bleach and other cleaning agents down your sink drains, and they mix in your pipes, you can contaminate the air in your home with the resulting gas created.
From the floor of the bathroom, to the walls concealed by the tiles, the waste and moisture can allow different kinds of microorganisms to thrive. The waste, the stale water and the microorganisms will collectively cause a weird smell.
P-traps can dry out as quickly as a month, sometimes even less than that. This happens most often in winter. To prevent your P-trap from drying out, run the sink or shower for a minute or two once a week to keep water flowing and your P-traps from drying out.
The first step in getting rid of your sewer gas problem can be easily accomplished by an odor detection test commonly referred to as a “smoke” test. This process involves isolating the sewer system by pushing colored smoke through a roof stack and blocking off the drain line with a test ball.
Usually, the escape of sewer gases out of the drains signals a possible backflow next. There are also times when the inlet, outlet, or baffles of the septic tank get clogged up, too. These also result in the presence of septic odor in the house.
If you have a leak in any of your vent or drain pipes, sewer gases can escape out of the leak and stink up your home.
The smell is likely strongest at floor level or at the drain. While it might come and go (or you may become so used to it you no longer notice it), it's not fixed even if the smell dissipates for a while.
