Does Vanke Property agree to change the second floor to independent launching?

Vanke Property does not need to agree to change the second floor into an independent launch. According to the relevant information, the change of the independent sewer on the second floor does not require the consent of the property. When the second floor is converted into an independent sewer, you can directly enter the main water pipe on the first floor. If the water pipe is hidden, it will be very troublesome to change it. Valves can be used directly, which can restrict water from flowing out of the pipeline and not flowing in.
