RE: copper supply lines

It's called water hammer...it happens when the pressure spikes as you shut off the faucet. An accumulator tank will minimize it somewhat as the diaphragm or bladder will absorb the surge. The other option, as used in household plumbing is to install a riser above the highest faucet. Essentially is is a foot or two of dead ended pipe that will always only have air in it. The air cushion will reduce the hammer also. Most likely, your new pump is of higher pressure than the old one, as well as all the seals and check valves working 100%.
