Sources of Odours in Bathroom Sewers

When the bathroom sewer starts to smell, all other tasks in the home are dropped, and getting rid of it becomes top priority. To get sewer odours fixed, determining its source is the first thing you need to do. Once you have determined the source of the odour, you can then proceed to fix it yourself or call a reliable and highly-reputed plumbing company to do it for you.

The Sources
If sewer odours have invaded the bathroom, you can look at three possible sources of the problem. These are the shower drain, sink drain, and the toilet.

Sewer odours usually manifest in sinks and showers that have not been in use for a very long time, like those inside guest houses or inns. Expect the odour to be strongest near the drain if these are the source. On the other hand, if the odours are strongest from the toilet, you might have caught the smells emerging from the shower and sink on occasion, too.

When the smell of sewage comes from the shower or sink, the unsealed trap in the drain pipe is the cause. The drain trap is a curving pipe section often filled with water, which prevents any sewer gases from backing up and entering the home. If a drain is not used for a long time, all the water in it evaporates and is not replaced, thus unsealing the pipe.

Sewer odours rising from the toilet bowl are caused by a blocked roof vent. This vent serves to remove all harmful sewer gases, and when it is blocked, sewer gases will start building up, and eventually, it forces its way around different parts of your plumbing, most notably the toilet bowl.

What can you do?
To keep any sewer odours out of the drains of showers and sinks, make it a habit to run water directly into the drains. Running water for more than ten seconds refills the trap with water and replaces those that have evaporated. Once you have done the things mentioned above, call in plumbing experts to find and clear out any blockage in the stack vent. This way, sewer gases can be vented normally and keep them from forcing their way around the bathroom.

Sewer gases in the bathroom are not just unpleasant, they are also dangerous. Due to the presence of hazardous components, like methane, exposure can cause health problems such as nausea, vertigo, headaches, and unconsciousness. Not only that, they can also cause fires and will even explode at high concentrations. Thus, when you smell sewage anywhere in the bathroom, make sure to get it sorted out immediately.
