Why does the bathroom at home smell so much

I recently helped a family is that the toilet is very smelly, sometimes downstairs also find to say that the roof is leaking, (under the toilet) I moved the toilet down to see, it turned out that the toilet drain and the floor drain link is not bonded with cement There are large seams, resulting in no vacuum when flushing will not be directly sucked into the drain, and the anti-odor elbow is very smelly due to the accumulation of stool without vacuum stasis, and the sewage that is not embedded in the nozzle will seep into the residents downstairs, pile a circle of cement at the nozzle, sit on the cement at the toilet mouth, because the nozzle is not breathable, Re-stool is suctioned directly in a vacuum, and the stool will not smell if it does not leave stasis.

In this case, you have to analyze it carefully to see which side of the smell comes from. On the one hand, the floor drain seal did not reach 50 mm, and you see the drain of your hand basin, and there is the problem of positive and negative pressure in the pipe, if you live in a high-rise building with more than ten floors, and your home is on the ground floor, you can move a stool at seven or eight o'clock in the morning to see where the floor drain is, and you can understand the positive and negative pressure of the pipe. If it's a floor drain, then change it, don't believe the bargains in the teens and twenties.

I do the decoration construction clearly, many companies use more than a dozen yuan of water seal floor drain, these have long been outdated, I generally recommend the submarine floor drain to customers, you can change the better floor drain, resist the aftertaste. If the ventilation is not good, you can install a ventilation device.

The most likely peculiar smell in the bathroom is the overflow smell of the floor drain, because there is generally no backflow bend under the floor drain, and the odor can directly enter the room through the floor drain; 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 from the top of the sewer pipe, and then it is possible that there is stinky water in the sewer pipe of the wash basin. Solution: Lift the floor drain cover when the smell is out, try whether to exhaust from the floor drain mouth, especially the odor, if there is, then prove that the floor drain is full of odor, you can change the floor drain or floor drain core to prevent odor, it is sold in many decoration markets or decoration supermarkets such as B&Q, if it is convenient, many of them are sold on the Internet, if the wash basin smells, you will check the pipe under the basin and clean it up; Secondly, clean the sanitary corners.

If you solve the problem of the source of the odor, you can consider supplementing it with air fresheners, fragrant flowers, fragrant waxes, etc.

The sewer does not have a submersible bend, so the gas in the pipe will escape. If not, it should be a hygiene issue.
