How Do I Fix the Problem of a Drain Smell in My House?

What Are Causes of Drain Smell and Their Solutions?

Wax Ring on the Toilets Can Cause Drain Smell

Problem

The drain system is linked to toilets via a wax ring that forms a tight seal between the toilet and the drain. This crucial component ensures that no unpleasant smells or hazardous gases infiltrate your living space.

Nonetheless, detecting any unusual odours within your household could indicate a defective wax ring on one or more of your toilets. When the wax ring fails, it can cause water to leak from the base of the toilet, leading to the growth of mould and mildew, and most notably, the foul smell you are experiencing.

Solution

Thankfully, the fix to this issue is relatively simple. All you have to do is to replace the wax ring on the drain to eliminate the sewer gas smell and restore a comfortable environment in your home. It is important to note that a licensed plumber should only carry out this task to ensure it is done correctly and safely.

Don’t Forget to Check the Kitchen Sink

Problem

It can be difficult for people to identify the source of a drain smell, as it can affect various plumbing systems in a home. Specifically, some may mistakenly ignore when a sewer gas odour is coming from their kitchen sink, thinking that another issue could cause it.

Solution

If the drain smell is suspected to be caused by a dirty overflow system, it is unlikely that sewer gases are to blame. In this case, cleaning the overflow system can be a solution to eliminate the unpleasant odour.

This is particularly relevant when the issue is coming from the kitchen sink. You can likely improve or entirely remove the smell by cleaning the overflow system.

Check the Vent Pipe

Problem

A malfunctioning vent pipe in a plumbing system can lead to the release of unpleasant sewer gases into a home or building. It may have a crack or could have been installed incorrectly, causing the bad odour.

Solution

If the vent pipe is identified as the source of the sewer gas odour, repairing or reinstalling the pipe is necessary to fix the problem. Addressing the issue ensures that your plumbing system functions correctly and maintains a safe and comfortable living environment.

A Blocked or Improperly-Installed Vent

Problem

A blockage in a plumbing vent can lead to a drain smell in a house, which can be a frustrating and unpleasant experience for anyone. Various factors, including physical blockages, rust and decay deterioration, and animal nests, can cause the issue.

Solution

Regardless of the cause of the blockage in the vent, the solution is typically straightforward. Clearing the blockage or replacing any corroded or damaged parts of the vent can help restore proper airflow and eliminate unpleasant odours. This is particularly relevant if the blockage is causing a sewer gas smell in the house.

It’s important to note that working with plumbing vents can be hazardous and should only be done by a licensed plumber with the appropriate training and equipment. By promptly calling a professional, you can address the issue quickly and ensure that your home remains free from any unpleasant odours.

Sewer Gases Coming from the Shower

Problem

Like the kitchen sink, another uncommon reason for the drain smell may be the sink installed in your bathroom. A potential cause of the drain smell in a shower is a buildup of materials within the drain that can accumulate bacteria and cause an unpleasant odour.

Solution

To eliminate the odour, it’s important to thoroughly clean the area using a cleaner specifically designed for the purpose. In some cases, removing the drain to clean the outside of the shower may also be necessary.

It’s important to remember that using aggressive chemical cleaners can harm both plumbing systems and the environment. Therefore, selecting a suitable cleaner and adhering to the manufacturer’s guidelines meticulously is crucial.

By taking prompt action and addressing the issue, you can ensure that your shower remains a comfortable and pleasant space to use.

What Are the Dangers of a Sewer Gas Smell in the House?

Exposure to sewer gas in the home can pose various health hazards, ranging from minor to severe. The gas, which contains a mixture of toxic and non-toxic gases such as methane, hydrogen sulphide, ammonia, carbon dioxide, and nitrogen, can cause symptoms such as headaches, nausea, dizziness, fatigue, and eye irritation.

In some cases, prolonged exposure to sewer gas can result in more severe health effects, including respiratory issues, loss of consciousness, and even death. Moreover, the presence of sewer gas in the home could indicate a more significant problem, such as a blocked or damaged sewer line, which could lead to serious water damage and structural issues if left untreated.

Therefore, it’s crucial to promptly address any sewer gas odour in the house and seek professional help to identify and fix the underlying problem.

How Do You Get Rid of Sewer Smells Fast?

While individuals may try various remedies mentioned above, there are instances where engaging a professional becomes imperative to safely and efficiently eliminate a sewer gas odour within the household.

Although simple cleaning approaches may suffice in most cases, it is advisable to seek expert assistance when there is a likelihood of extensive plumbing damage, or specialised knowledge is required, such as when dealing with a cracked vent.

Opting for professional intervention increases the chances of resolving the issue more comprehensively in the long run and ensures greater dependability and trustworthiness of the plumbing systems.
