Can the water in the ancient town be polluted by the water discharged from the toilet in the bathroo

No, there is a drainage main in the kitchen, and there is not a drainage main in the bathroom.

If the indoor conditions permit, you can consider using a mobile machine called "water lifter", if you don't know this kind of machine, you can consult the older people in the countryside, more than 30 years ago there were many such agricultural machinery in the countryside, they will know that this kind of agricultural machinery used to lift water from the well to irrigate the farmland, of course, now there is no use I am afraid that I can't buy it, I can only find a way to make it. It is recommended that you use this tool to extract sewage from the basement, considering that you do not use tools such as pumps, even if it is manufactured, it is not troublesome, the parts that are not easy to manufacture are sprockets, chains are ready-made for sale, trays, brackets, etc. are very good for processing and manufacturing, I think this is very ideal, the biggest advantage is that blocks such as feces are not easy to block, because the ring chain is continuously extracted, there is no residue in the barrel, only very little remains at the bottom of the sedimentation tank.

It's okay in winter, it's best not to do it in summer, the water after washing clothes has other smells such as sweat, and the water will be rancid after a while, of course, according to your own situation, if the conditions allow, or don't want it.

Normally, it is mainly caused by evaporation, the water will become water vapor and released in the air, and the water will become less and less, and the higher the temperature, the faster the evaporation.

First of all, it depends on the service life of your house, if the warranty period has passed, it should be 5 years waterproof, there is no developer to compensate for the loss, and you can only pay for it yourself after it is over, and the property is not responsible The responsibility of the property is the common area.
