What is the cause of the smell in the bathroom

1. Floor drain. There is a peculiar smell in the bathroom, which may be due to the blockage of the floor drain, which causes the dirty things to be discharged in time, and over time there is a phenomenon of decay, and there is an unpleasant smell in the bathroom. If the quality of the floor drain is relatively poor and witherable, it is recommended to replace a non-Hengchun anti-odor floor drain, so that whether it is drainage or deodorization, it can achieve twice the result with half the effort.

2. Toilet. Due to the special function of the toilet, once a blockage occurs, the unpleasant smell is disgusting every minute. Therefore, the reason for the smell in the bathroom may also be the clogged toilet, or there is a broken place on the toilet, and the cause can be solved in time to solve the problem of odor in the bathroom.

3. Trash cans.

Trash cans in the bathroom are also a source of odors. Many friends will often forget to take out the garbage due to laziness, and in the long run, there will be more and more dirty things in the trash can, which will produce peculiar smells and breed bacteria at the same time, which is harmful to human health.

The floor drain digging is connected to the drainage pipe, and it also plays a role in insulating odors and small flying insects. Now there are U-shaped floor drains and T-shaped floor drains on the market. According to the length of the trap, the U-shaped floor drain is divided into shallow water sealing floor drain and deep water sealing floor drain.

When the water in the trap evaporates dry, the smell of the sewer pipe will rise. The T-shaped floor drain is designed by gravity flap, which is closed under normal circumstances, and when draining, gravity will forcibly flush the seal away, and the water will automatically return to its position after shooting, and the design with magnets will be firmly absorbed. In terms of airtightness:

T-shaped floor drain is stronger than U-shaped floor drain, generally floor drain has peculiar smell, the first consideration is that the U-shaped floor drain water storage is drained, only need to pour some water to play a role in sealing.

There are two kinds of sink drainage, one with an S-bend and the other without it. The S-bend plays the role of changing the odor in the interval, and if there is no S-bend, you can make the hose into an S-bend. Generally, the odor is caused by the connection with the sewer pipe is not sealed, and the solution is to reseal it with glass glue.

At the junction between the toilet bowl and the sewer pipe, there is a sealing ring, also called a flange ring. A lot of odors between the nuclei of sanitary branches are caused by the sealing ring is not properly installed. The solution is to remove the toilet bowl and reinstall the seal.

Bathroom odor should be solved at the root. The reasons for the possible odor are:1

The most likely is the overflow smell of the floor drain, because there is generally no backwater bend under the floor drain, and the odor can directly enter the room through the floor drain; 2.The drain of the toilet or wash basin may have an odor, one may be a problem with the backwater bend, the other may be that the air pressure is too low when the weather changes, and the smell comes up, and then it may be that there is stinky water in the sewer pipe; 3.There may be some sanitary dead corners in the bathroom, such as garbage, dirty water, etc.

Solution:1When the smell is out, open the floor drain cover, try whether to exhaust from the floor drain mouth, especially the odor, if there is, then it proves that the floor drain is smelly, you can change to a deodor-proof floor drain, which is sold in many decoration markets or decoration supermarkets such as B&Q, and even sold on the stalls; 2.

If you find that the toilet has a smell, clean it with cleaning liquid, and if the wash basin smells, you check the pipe under the basin and clean it up; 3.Clean the sanitary corners. In addition, an exhaust fan in the toilet is essential, because the smell of other people's homes may be transmitted to your home through the exhaust duct, and the exhaust fan can help you block the smell when you are not working, and can exhaust the smell you don't want when you are working.

After solving the source problem, you can consider using air fresheners, fragrant flowers, fragrant waxes and the like to beautify the smell of your bathroom.

The odor in the bathroom mainly comes from the following places:

1. Floor drain back smell: The floor drain drain in the bathroom should have a reverse water bend, and the water is usually sealed to prevent the odor. At present, in order to increase the floor height and reduce the cost, many new residential areas have canceled the anti-drain under the floor drain, but adopted a new type of anti-odor floor drain to ensure that the sewer odor does not escape.

These odor-proof floor drains are often made of PVC materials, far less beautiful than the stainless steel and copper floor drains sold on the market, and many owners have replaced the floor drains that look beautiful and the actual quality is unqualified when decorating, resulting in bathroom odors, and it is recommended to use odor-proof floor drains.

2. Sealed sewer pipe odor: The connection between the sewer pipe and the sewer pipe of the sink is not strictly sealed, which becomes the channel for the sewer odor to enter the room. Since the sewer interface is in a relatively hidden place, it is easy to ignore it when the decoration is completed and accepted, and it should attract the attention of the owner.

You can ask the renovation worker to seal the gap at the interface with glass glue or other adhesive so that the gas cannot be discharged.

3. Toilet aftertaste: The structure of the toilet is unreasonable, and the water seal is not strict, which will cause the backsmell of the sewage pipe, or the sewage pipe is misplaced during the installation of the toilet, the aging of the base sealing ring or the poor sealing of the base, which will lead to aftertaste and even leakage of sewage, so it is best to reinstall.

The drain smells bad, or maybe the smelly dirt in the floor drain is stuck.

Odor in the bathroom is a headache, where does the smell come from?

Generally, the first thing that comes to mind is floor drain, basin sewer seal, toilet seal, and so on.

When these locations are confirmed to be fine, but there is still a strong smell in the bathroom, what is the root cause of the problem?

I have encountered such a situation, the newly renovated house, the floor drain is sealed with water, the water under the wash basin is made of a backwater bend, and the toilet is also strictly sealed, but the bathroom still often has an obvious smell.

After a period of observation, I found that the problem was coming from the bathroom exhaust vent.

Nowadays, in order to improve the sealing and sound insulation effect of the house, most of the people use broken bridge aluminum doors and windows, and the sealing performance is very good. At this time, if the kitchen turns on the range hood, a large amount of air is discharged outdoor, the doors and windows are sealed very tightly, and the outdoor air has no channel to supplement the room, at this time, the bathroom exhaust outlet forms an airflow backflow, although the exhaust outlet is also installed with a check valve, the sealing is very poor, the airflow backflow is obvious, the smoke of the cigarette can see the air backflow at the exhaust outlet, and even the backflow can be felt by hand.

Solution: If there are windows in the kitchen, be sure to open a little window when turning on the range hood so that the outdoor air can form convection.

If the kitchen doesn't have windows, open a few windows in the living room or bedroom adjacent to the kitchen to allow air to come in.

The bathroom exhaust outlet is a high-quality check valve, preferably with a rubber sealing ring.

According to the length of the trap, the U-shaped floor drain is divided into shallow water sealing floor drain and deep water sealing floor drain. When the water in the trap evaporates dry, the smell of the sewer pipe will rise.

2. The T-shaped floor drain is designed by gravity flap, which is closed under normal circumstances, when draining, gravity will forcibly break the seal, and automatically return to the position after shooting the water, plus the design with magnets will be firmly absorbed. In terms of airtightness: T-shaped floor drain is stronger than U-shaped floor drain, generally the floor drain has a peculiar smell, the first consideration is that the water storage of the U-shaped floor drain is drained, and only some water needs to be poured into it to play the role of airtight shirt training.

The S-bend plays the role of insulating odors, and if there is no S-bend, you can make the hose into an S-bend. Generally, the odor is caused by the connection with the sewer pipe is not sealed, and the solution is to reseal it with glass glue.

4. Source of odor: toilet seal. At the junction between the toilet bowl and the Zhikai sewer pipe, there is a sealing ring, also called a flange ring. Many bathroom odors are caused by the sealing ring is not installed properly. The solution is to remove the toilet bowl and reinstall the seal.
