Check your piping for excessive runs without proper supports.
A lot of BUMS use band iron in lieu of the better clevis hangers for horiziontal runs and never follow the proper lenth between hangers.
Check your lines 1st
2nd make sure someone didnt partically close a gate valve and try to use it for throttling.
3rd Try to find out your incoming pressure and the size of your piping send me an E mail and ILL give you your velocity WHICH maybe too high.
Check your faucets for a loose washer or seat
Think about installing a shock asorber (approved type of air chamber) as you cant compress water But you can compress air and this cushion would take up for shock waves
Try your washing machine/ dishwasher to see if they also cause this kind of vibration
