Is it useful to call 123 19 when there is water leakage upstairs?

If there is water leakage upstairs, you can try to call 123 19 for repair. 123 19 is a national unified urban water supply hotline, which can provide relevant water service and consultation. If there is water leakage upstairs, timely maintenance can avoid water loss and potential safety hazards, and also protect the living environment of downstairs residents.
