Article 34 of the Measures for the Administration of Residential Decoration: If the decorator encroaches on public space due to indoor decoration activities of residential buildings, causing damage to public parts and facilities, the urban real estate administrative department shall order him to make corrections, and if losses are caused, he shall be liable for compensation according to law. To sum up, the water meter room belongs to the public * * * area and is included in the scope of property management. The owner installed a water purifier in the water meter room, which first violated the public area. At the same time, the installation of water purifiers by property companies is equivalent to an increase in security risks. For example, once the water purifier leaks and involves losses, both the property and the owner are responsible, so it is normal for the property company to disagree with the installation. As the owner, the water purifier should be installed in the indoor personal exclusive area as far as possible.
