Hi all,After looking on the grundfos web site for a replacement for my 15/60 pump I purchased a UPS2,it told me it was a direct replacement.I could use the old body and just change the motor.Looking at the instructions (page 5) it shoes the pump in a vertical position pumping upwards,i need it to pump downwards so is it O.K to turn the pump upside down.I have gravity hot water and pumped heating,pump on return to boiler.its also got a suppressor lead I know why,but its got the same fittings on both ends does it matter what way round it goes
