A drain is a primary vessel or channel takes the wastewater to sewers or stormwater mains. It includes the waste fluids from bathrooms, kitchens, or washing areas. An efficient plumbing system helps proper drainage and contains the smell of wastewater flowing through the pipes.
However, any issue with the plumbing system, such as blocked drains or sewer gas leaks, can lead to annoying smells in the home.
Smelly odours are the first indications of a compromised drainage system. That’s why it is vital to identify the sources of the sewer gas leak or the blocked drain to solve the root cause of the smell in the house.
The following are some of the possible causes of smelly drains:
When food leftovers are directly washed out into the drains, it can cause smelly drains and clogged pipes. The incomplete decomposition of food waste inside the drainage pipes can develop nasty odours.
The kitchen sink deals with different waste substances, such as dish soap, food waste, etc., which gets buildup over time. Therefore, a grimy or unclean overflow system can lead to sewer gas odour from the kitchen sink.
Sewer gases can also lead to drain smell from shower floor drains. It may be due to a buildup of waste materials, including body oils, hair, soaps, shampoos, and other liquids flowing through them. Accumulated waste substances can also lead to the growth of bacteria, causing smell.
U-bend, a sewer gas trap is present under the kitchen sink. It can get dry if you have not run water for a while or you have been away from your house for holidays. Then, it becomes inefficient and cannot stop sewer gases from escaping out of the plughole. Moreover, blockages or leakages in the U-bend can also cause sewer smells.
The vent pipe assists in managing the plumbing system’s pressure and moves odours outside the house. A crack or incorrect installation process can lead to a malfunctioning vent, resulting in sewer gas leakage. Moreover, a bird’s nest, leaves, rust, snowfall, etc can also result in a blockage inside the vent.
A wax ring is used for sealing the toilet drains, and a faulty wax ring can cause a drain smell in the house.
Sewer gas is the by-product released during the breakdown of waste substances. It is not only irritating to the senses of smell but is also harmful to health as it contains ammonia, carbon monoxide, esters, hydrogen sulphide, methane, nitrogen oxides, and sulphur dioxide.
Its potential health problems include breathing difficulties, cough, eye irritation, fluid accumulation in the lungs, sore throat, etc. Consistent exposure and higher concentrations of hydrogen sulphide can lead to severe issues, such as dizziness, unconsciousness, pneumonia, etc.
Drain smells can get worse with time and are required to be resolved quickly. After identifying the leading cause of drain smell in the house, you need to tackle the issue with these possible measures:
You can follow the above-mentioned steps to solve the issue of drain smell in your house. But in severe cases, you will need to hire a professional expert to resolve this problem effectively. The professional intervention will help in the technical management of the issue, ensuring safety with reliable services.
Regular cleaning and rinsing of drains are efficient strategies to keep your system running smoothly and prevent materials buildup.
