Lets think about this. The pump is going to be on springs and will be able to move up and down and side to side. When the pump starts, the impeller will rotate creating a torque. The torque will push down on some springs and lift up on others. Whereas the torque is usually absorbed by the pad, it will now be absorbed by the pipe and fittings attached to it (until the springs max out). I will be outside with a catcher's mitt to collect the flying debris.
