It's not water hammer which is just one bang when a solenoid valve as on a dishwasher or laundry washer closes. It is not air getting into the lines because her water lines have pressure in them. Water shoots out any opening. No air can get in. My experience with vibrating pipes is the old type of hard rubber washer in a stop and waste valve used everywhere at that time. The bib screw that holds the washer in place gets eroded away allowing the washer to move as water flows past it. sometimes it will be in just the right position to open and close the valve very rapidly as the water flows through, setting up a vibration. Stop and waste valves can be readily opened up with a fairly large wrench just under the packing nut, but they will be stubborn of course with age. Be prepared to replace them probably with ball valves.
