The house could have 3 showers, Dishwasher and Laundry all going at the
same time. What size booster pump should I be looking at? I was thinking
a 1HP minimum.

HP is only one factor. You want to look at the volume (GPM) and the
pressure. Determine your requirements first.


Then what is the best way to connect the booster pump to the PVC? I was
hoping to get some sort of Flex piping similar to the stuff that is
connecting the Pool equipment. Help cut back on the vibration to the rigid
conduit and to the structure.

If the pump is properly mounted and the PVC is properly connected and
supported, it is better than a flex pipe that can flex and crack over time.
