If you have constant smells around your toilet it could be because your bathroom isn't vented correctly.


Why you need to know how to fix toilet smells from your bathroom.

Nu-Trend is a licensed plumber in Sydney and one of the most common services we get called out for is to help people fix a blocked drain either in the kitchen, laundry or bathroom. In lots of cases it is because something has been lodged in the waste pipes like food or other debris that a plunge or high pressure jet blast can fix. Most people will realise they have a blocked drain because their sink doesn’t empty quickly or they see water pooling around the external overflow drains.



Sometimes though you may have a very slow draining sink that begins to gurgle and this can be a sign that the correct venting hasn’t been installed in the plumbing system. The gurgling sound is caused by air being forced through water in your drain trap. It’s like pouring a drink too quickly. In many cases the gurgling sound will often come from a shower or bath tub, but depending on the situation it can also come from your vanity sink or toilet. Alternatively, you may be getting strange toilet or sewage smells even though there is no visible blockage in the toilet bowl, this could also relate to the venting of your plumbing system.


You might even hear a gurgling noise when you are using your washing machine and it is trying to empty the water during a drying cycle. Even in this situation it could mean a shared waste pipe is partially blocked. The blocked waste pipe does not allow the water from the washer to pump out fast enough. It could be because of lint and soap scum from the washing machine that is partially blocking the waste pipe or an incorrectly vented plumbing system that isn’t coping with the demands required.


What was causing this toilet to smell?

We attended this property which was a commercial retail butcher shop that had an upstairs residence because they wanted us to inspect the sewer smells and gurgling they were experiencing from the bathrooms on the property on both levels. This building was actually about 10 years old and had been suffering from issues since it was built.

We realised fairly quickly that these situations are normally due to a blockage but potentially an incorrect plumbing installation or venting set up. 


Plumbing problem #1 – on the first visit we found two obvious causes that needed immediate repair. The first issue we found was the grease trap and the boundary trap both had caps on the low level vents. We replaced these with micro flaps that will allow the sewer to have adequate atmospheric pressure when the fixtures inside are in use or being flushed with water. 


Plumbing problem #2 – We then inspected the roof in search of a high level vent which we couldn’t find. With further inspection inside the ceiling we found an open 50mm sewer vent.


We immediately began to rectify by plumbing problems by redirecting the venting up through the roof and sealing it with This was Decktite to prevent any water leak issues. The sewer now has air flow from top to bottom and there are no longer any smells or gurgling.

How did this plumbing problem occur?

How to fix toilet smells? Well apart from maintaining healthy bowel movements with a balanced diet and exercise you can avoid smelly toilet smells by having the correct plumbing system set up at your property by a qualified plumber.


There should have always been a vent installed from the outset and this should have been included in the original scope of work when the building was constructed. Instead this plumbing problem has caused countless years of headaches and now over $500 in repairs. 


If it was done during construction it meant that there was no need to have plumbing call outs later on and everything could have been allowed for to provide a high quality bathroom plumbing finished project.

How can you fix a gurgling drain?

Nu-Trend is a qualified, licensed and experienced plumbing service that can help diagnose and repair a gurgling drain. We would check things like 

– Check for problems in the Installation of the sink vent.

– Check the air admittance valve.

– Check for clogs or obstructions in the drainage pipes with a CCTV camera inspection.

– Check for external waste in the sink vents.

– Do a high pressure flush of the sink.

– Check for any other main vent issues.

Is fixing a smelly toilet a DIY job?

While some people might like to try changing a tap washer themselves, trying to identify the cause of plumbing issues can be quite difficult when it comes to understanding how the full system is working. So attempting to do your own repairs could lead to further issues down the track.


You should always opt to use a fully certified and licensed plumber.
