You Can Hear The Difference Between Hot and Cold Water

Yeah the hot makes the pipes shake while I’m trying to sleep goddammit 

Haven't read the article but it sure sounds different in my shower. When I first turn on the hot, all the way, it sounds like water. When the hot water from the tank at the far end of the house arrives a couple of minutes later the sound gets a lot "softer" in tonality - not in volume. I then add some cold - sep. faucet - but not very much. After a minute or so the cold water from the pressure tank next to the house arrives and the sound gets "harsher".

Hot makes a racket going down the kitchen pipes.  Expanding pvc pipes anchored to wood?
