Some citizens have reported that the property requires the replacement of water meters each as high as 400 yuan. In this regard, Liu responded that water meters are compulsory measuring instruments managed by the state. According to the national regulations, the domestic water meter is replaced every six years. The water supply group replaces the water meters for residents in the central city free of charge, and individual communities are supplied by property companies. Due to the property rights issue, the situation is more complicated, but basically follow the principle that whoever owns the property rights pays.
