I have pump feeding a liquid to a distillation column. I have defined a functional location and the pump defined as an equipment is placed on it. Also I have defined a fucntional location for the distillation column. There is piping connecting the pump and the distillation column. A leak is found on the pipe midway between pump and distillation column. It is not correct to create a notification for the pump or the distillation column to check the leak. On what object should I create the notification and also how should I define piping as an object.
