Who is responsible for the frost crack of the fire sprinkler?

If the fire pipeline in the community is frozen and cracked, it must be the property company in the community. First of all, the fire pipeline originally belonged to the public area. Since the property management company collects property management fees, it should serve the owners. In addition, the pipeline frost crack is not caused by the owner, so the responsibility of pipeline maintenance should also be borne by the property company. However, if the fire pipeline is damaged due to the owner's personal reasons, then the property company in the community does not need to bear this responsibility. Fire pipes are very important. If there is such a problem as water leakage, we must inform the property management company in time and let them send specialized workers to repair it.
