What are some of the problems that can cause odors in the restroom?

The floor drain should have a draft of 5 cm, in addition to the flush toilet drain designed with a reverse bend when building a house in the past, the bathroom and kitchen floor drain drain also have a reverse bend, usually rely on the sealing of water to prevent odors. 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, which are far less beautiful than the stainless steel and copper floor drains sold on the market.

Seal the sewer pipe to connect part of the sink drain pipe and the kitchen drain pipe to the sewer connection, these details can become a passage for the sewer odor to enter the room if not strictly sealed. 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. The specific practice recommended by experts is to ask the renovation worker to seal the gap at the interface with glass glue or other adhesive so that the gas cannot be discharged.

Some corners of the bathroom, such as: the gap between the bathroom cabinet and the ground, the gap at the back of the toilet, etc., these dead corners of the bathroom are not easy to clean, and at the same time, they are easy to ignore in the daily cleaning. The floor drain is not tightly sealed or the water seal fails the floor drain can be divided into water seal type floor drain and mechanical seal type floor drain according to the sealing method, wherein the water seal type floor drain is sealed by a water trap similar to the "S" type, and the water trap must have enough depth to achieve effective sealing, if the water seal structure is too shallow, or the water in the water trap evaporates, the sealing effect will be lost, resulting in odor leakage; Mechanically sealed floor drains are sealed by gravity or water pressure pressure pressure sealing valves, and if there is a problem with the opening and closing structure, such as hair tangling or debris blockage, the seal will also fail.

In addition, residues such as bathing hair in the shower room flow into the drain sewer pipe and remain on the wall of the floor drain for a long time, which will stink after deterioration and cause odor in the bathroom.

The drain outlet of the wash basin is connected to the sewer pipe through the drain pipe, and there are three main places where the aftertaste is easy to occur.

The drain pipe is directly inserted into the sewer pipe, and there is no seal at the interface; The drain pipe does not have an S-shaped trap water seal, or there is a sealing device in the drain pipe, but the seal fails due to foreign objects such as hair; Residues such as hair adhere to the walls of drain pipes, and after a long period of time, they deteriorate and form a foul odor. Toilet aftertasteWhen installing the toilet, the toilet bowl and the sewer pipe are sealed by an "H" shaped flange, and the part of the toilet that is in contact with the ground is glued to fix and seal. If the toilet is misaligned with the sewage pipe during installation, or the flange and pipe of the toilet are not tightly sealed, and some even miss the flange, and the sealant between the barrel and the ground will fall off, it will cause the smell of the sewer to emanate from the gap.

In addition, some toilets have 2 small holes in the back, and if the bottom and PVC sewage pipe are not sealed, they will smell outside.

Bathroom odor should be solved at the root. The reasons for the peculiar smell are: the most likely is the overflow 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; 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; There may be some sanitary dead corners in the bathroom, such as garbage, dirty water, etc.

Solution: Lift the floor drain cover when the smell occurs, try whether to exhaust from the floor drain mouth upwards, especially the odor, if there is, then it proves that the floor drain is full of odor, you can change to an anti-odor floor drain, which is sold in many decoration markets or decoration supermarkets such as B&Q, and even sold on the stalls.

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; 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.
