API 610 Pump Nozzle Loads

When the Suction and Discharge Nozzles of the pump are considered individually anchored the nozzles loads exceed the API specified limit in an existing system. Then I freed the 2 Nozzles, anchored the Pump Base and connect the 2 Nozzles to the base by rigid bodies of zero weight. Now it is found that the Global Forces at the elements connecting to the nozzles are much lower than API 610 Limits. Is this apporach of evaluating the nozzle load okay. [In actual the Pump Base and the 2 Nozzles form single rigid body. But in the model I described there are two regid bodies, each nozzle individually connected to the base] Or is there any other approach? Or should I necessarily do something with the Piping Layout.
