Bathroom exhaust fans are an essential accessory for the bathroom, yet they are ignored. They do not receive the due attention they deserve.
While maintaining and improving our homes, we often forget about addressing the exhaust fan’s maintenance and health.
It is due to these factors that these exhaust fans stop working at times. The malfunctioning can be so serious that the exhaust fans fail to perform the way they should.
A well-maintained and perfect-performing exhaust fan ensures a safe home with a healthy and hygienically sound bathroom all the time.
Why Do We Need The Exhaust Fans?
Like the kitchen exhaust that expels the steam, smell, and other unwanted from the kitchen, the bathroom exhaust fan’s job is to expel the moisture and the foul smell.
Whether you are taking a hot bath or spending extra time in the bath, it is essential to keep the air moving.
The fans are highly important, especially when you have small-sized bathrooms with limited space.
If there are no large windows in the bathroom to allow proper ventilation, it is the exhaust fan that can do the right job.
Exhaust fans are very important as if the steam or moisture stays for a long time, it can cause mildew growth spores.
The unwanted growth of midland mildew would further lead to bad odors. Thus, in the absence of the exhaust fan or the faulty exhaust fan, the problems can worsen.
It is important to remember that unlike the kitchen exhaust, the bathroom exhaust is multitasked. Thus, it is essential to keep the bathroom exhaust prim and proper.
One of the common problems reported concerning the bathroom exhaust fans is the fan blowing the air down instead of sending it out.
Causes Of Air Blowing Down
If your exhaust fan is blowing the air down, it is indicating the following causes:
1. The backdraft flapper is not in the right place
The draft flapper is fixed to the bathroom exhaust fan to control the vent’s movement for the airflow. Thus, it prevents airflow into the vent pipe.
The flappers are either placed in the fan at the point of attachment of the vent or closet, the point where the vent pipe exhausts the air outwards.
Some more sophisticated exhaust fans have these flappers in both places. If this flapper is stuck in a closure position, you may expect the air to come down.
2. It is essential to keep the vent pipe clean
If the vent pipe is filled with dust, dirt, or debris, you will likely experience failed airflow.
The debris keeps accumulating in the vent pipe, and if it is not removed well in time, it can turn out to be havoc.
3. The air would stop going out if the pipe gets damaged.
The kinked and the flattened pipes would also prevent the air from flowing freely.
These are the three main causes of blockage of the proper airflow. Thus, it stops the air from going in the right direction.
If the blockage has become stubborn, then you are likely to experience a backward flow of air. The blockage would prevent the air from going out and cause the bothering sound of the exhaust fan.
Correcting The Problem
1. Make sure to clean the fan thoroughly at least once a year. To start with, switch off the power source that you are using to operate the fan.
2. Carefully examine the grate that is covering the fan. Mostly it is fixed to the fan with screws. In some recent brands, these grates are attached with an easy to remove tension clip.
3. Remove the grate and clean it thoroughly with the mixture of warm water and dishwasher.
4. Use the vacuum to clean the dust accumulated in the vent pipe. The dusting cloth can help clear the dust on the fan blades.
5. Fix all the parts that you have removed while cleaning. Switch on the circuit and see if the fan is doing the job right.
It is very important to keep a close check on the fan that helps you get rid of the unwanted from the bathroom.
Besides regular cleaning, it is essential to clear the fan thoroughly once a year. The exhaust fan’s vent pipe is doing the tedious job of circulating the air in the right direction.
If there is a slight blockage in the vent pipe, the air will stop going out instead of staying within.
