One of the worst things that can happen as a homeowner is an unexplained and mysterious odor.
Especially one that’s emitting from the bathroom. AND ESPECIALLY IF IT’S FISH!
So, Why Does Your Bathroom Smell Like Fish?
Well, there are many reasons why your bathroom smells like a fish. One major reason is due to sewage gas. Corpses of animals in the wastewater tanks and clogged plumbing vents are also chief causes of this smell. And there is more!
What Causes Your Bathroom to Smell Like Fish?
You cannot battle with an enemy you have no idea about.
In this section, we will uncover the causes of that odd fishy smell in your bathroom.
It will help you mitigate on proper measures to combat the problem.
Here are the major causes:
1. Sewage Gas
Methane and ammonia are two major components of sewage gas.
It is emitted from decomposing human waste.
It is very unpleasant and can cause a lot of discomforts.
Sewage gas often smells like a fish or a rotten egg.
Long-term exposure to methane gas has been known to cause sewage gas poisoning and other related respiratory ailments.
You, perhaps, wondering how on earth can sewage gas enter the bathroom.
Well, sewage gas can find its way into the bathroom through poorly done plumbing leaking pipes that can open an entryway for sewage gas.
If your toilet remains unused for a long time, the pipes below it automatically run dry.
With no water to act as an effective deterrence to sewage gas, it enters the bathroom leading to that foul fishy smell.
Additionally, loose pipe connections and toilet parts can also create potential entryways of sewage gas into the bathroom.
Just to mention that clogged drains can create sewage gas reservoirs.
2. Electrical Wiring
Plenty of people would rule out the possibility of electric wires causing a fishy smell.
The truth of the matter, however, is that when electrical wiring overheats, they produce distinct odors making the room smell like a fish.
Overheating of electrical wires can occur due to loose wiring. Old wires also tend to overheat especially when they are overworked.
Besides causing a bad smell, they jeopardize the safety of the room’s occupants.
Many fires have occurred this way.
3. Animal Corpses
If an animal like a rat or lizard dies in the walls of your home, its body starts decaying.
The decaying corpse of such animals emits ammonia gas which diffuses to the entire house smelling like a fish.
It is not uncommon to have rodents dying in the home.
They are often very disgusting when they do.
Other than plaguing your home with a horrible fishy smell, a lot of health concerns are attributed to it.
Some folks may not even find the appetite to eat.
Others can vomit and the whole thing becomes a nightmare.
In case the animal dies near a cracked water pipe, there is no doubt it will contaminate it. This can even cause serious ailments.
4. Clogged Plumbing Vents
Plumbing vents are often designed to bar sewage gas from finding its way into the bathroom.
They are made to operate by providing ventilation which vents off sewage gas and bathroom odors.
However, they can get clogged due to a myriad of reasons.
Bird nests, for instance, can be a major issue. Leaves, animal carcasses, and other dirt can blog them and interfere with ventilation.
The result is a massive accumulation of sewage gas in the bathroom which spreads further into the other rooms.
