In case the discharge/suction pipes and/or the pump have thermal loads, the +Y support will not work under the elbow/short straight.

It is better not to use immediate support under the elbow/short straight in suction/discharge sides with thermal load in case the nozzle loads are satisfactory. Otherwise you may need to use spring can.

Be carefull! Very small vertical displacement can overload the pump nozzzles.

Hope it help.
