Do public water pipes in residential quarters need regular property inspection?

I don't know what you mean by public water pipes.

If it's a water pipe, you can see if the residents are there. If you go out, the water outside the water meter belongs to the maintenance scope of the water supply company, and the water meter inside the table belongs to the self-study scope of the residents and has nothing to do with the property.

If it refers to public sewers, the maintenance subject belongs to the property management company. (After the warranty period), however, regular inspection is limited to the visible part. If there is a problem with the buried part, the residents should report for repair.

Now it is illegal to stipulate group rent, but it is not illegal, depending on how the local administrative regulations stipulate it. For example, Shanghai stipulates that group rent is not a family member and will be fined.
