A buddy of mine just got a free used pump from his brother. His pump on his inground 20k gallon pool has been giving him troubles, so he wants to switch them out. Only thing is, his existing pump is 3/4 and the new pump is 1.5. Aside from maybe wasting electricity, are there any other concerns with overpowering your pump? Maybe putting undo stress on your pipes? Or potentially doing damage to the filter? Or as silly as this one sounds, even having such higher pressure coming out of the returns that children could hurt themselves?
