Does the methane gas from the toilet drain affect people?

It cannot be changed, one of the two calibers is not the same, it is necessary to change small to large, it is easy to block, even if the two calibers are the same, the reservoir is not the same, which is not conducive to urban sewage discharge.

Of course it has an impact! Put more bamboo charcoal packets at home, and grow more cactus cactus balls. Don't put a sticker on the market.

Depending on what kind of battery, the impact will be different, some batteries will be well sealed and will not produce pollution, and some batteries will seriously pollute water quality.

In response to this problem, as long as there is no water leakage or aging, it has no effect on the body.

To put it simply, some painted furniture may have an impact, it is recommended to place it elsewhere, or not to share a room with pregnant women, some furniture that makes too much viscose also has an impact, and the natural color of solid wood, if only the surface is polished, or the use of varnish, the impact should not be large. >>>More
