The toilet should be flushed frequently so that it will not smell, and by the way, pour some water into the floor drain and basin to prevent the water seal from evaporating.
It depends on how the toilet is installed. If the glue sticks to the floor, don't use it. If it is cemented, it may be required.
Not biogas.
Biogas is a flammable gas produced by the action of microorganisms (such as straw, weeds, leaves, human and animal manure and other wastes) under certain temperature, humidity and acidity conditions, isolating the air (such as using a biogas digester). Biogas is a mixture of gases containing methane 60 70, carbon dioxide, hydrogen sulfide, nitrogen and carbon monoxide. It contains a small amount of hydrogen sulfide, so it has a slight odor. >>>More
It can be changed, but it is easy to have sequelae, and the common ones are easy to block and the water is not smooth.
It's okay once in a while, and it's good to pay attention to it later. If you are a girl, you should pay more attention to hygiene.
