Who is responsible for the maintenance of water seepage in fire pipe network?

Depends on what kind of property you are. If the manufacturer has a fire maintenance unit, it is a fire maintenance unit. If not, please repair it yourself. If it is a residential property, it depends on the fire maintenance unit. If there is no residential property, please ask a plumber or find someone to repair it. If there is no property to see if it affects you, don't worry. If there is, you will feel unlucky and spend money to repair it yourself. If it is a village in the city, please find the village Committee.
