Along the serpentine belt and I need help figuring out what is causing the noise. The sound gets worse when you hit the accelerator The water pump was replaced less than 3 years ago

Use a tube like vac wand to ear to try and locate precisely. Could be belt is bad and slipping (grooves to worn) or your air pulley bearing or idler pulley beariing. Also check that bekt has good tension as tensioners can get stuck or loose tension.

I put the vacuum tube to each pulley and it sounded the loudest and most high pitched at the pulley between the waterpump and the AC. Does that mean much to you?
