There is always an unpleasant smell in the bathroom, especially in windy weather. How to solve it?

Check the floor drain first. If the floor drain smells, before installing it, think about whether there is a trap in your home. If installed, the problem of odor can usually be completely avoided. If there is really no trap, install a "floor drain treasure" under the floor drain. I hear it's easy to use. Wash basin and mop basin are also areas that must be tested. If they are odor-proof, it is very likely that the sewer pipe has not been intercepted for deodorization. Because the sewer pipe of the washstand is inserted into the pipe immediately, if it is not solved, there will be a gap and the smell will be reversed.

The solution is to seal the joint between sewer pipe and pipeline. The most direct and effective way is to block the outside with objects, so that there will be no steam leakage. The sewer pipe under the washstand is made into an N-shape to create a simple trap to prevent the smell from rising through the sewer pipe. At the same time, you can immediately clean the sewer pipe or floor drain with boiling water to melt the dirt on the wall thickness and reduce the odor discharge. There is a gap between the plastic hose for ventilation in the bathroom and the main ventilation pipe in the bathroom, which is not well sealed. Just take care of the surrounding styrofoam and seal it.

But all drainage equipment, especially drainage, has the problem of indoor ventilation. Nowadays, residential buildings are several floors short and dozens of floors high. There are tap water pipes of different sizes in the bathroom, including sewage treatment supervisor, washbasin sewer pipe, toilet sewage pipe, floor drain and the whole shower room pipe. According to them, the waste water will converge to the sewer supervisors in big cities. The most important physical principle is that wastewater will be discharged downward and cyclone will rise. If the toilet is not sealed properly,

The natural environment of the bathroom is wet and cold. If natural ventilation is blocked, it will increase the breeding of all kinds of germs, such as corners, cracks in tiles, back and bottom of pots, odor-resistant floor drains in shower rooms and poor sealing of pots, which will all become the sources of odor. Therefore, both internal and external environmental sanitation should be done well. In the sealing work, if the commission pollution system becomes a closed loop, it is not easy to have any problems!
