I just started noticing an occasional knocking sound in my basement which seems to be coming from pipes. Any ideas what is going on? Thanks

  1. I thought water hammer was a wave of hydraulic pressure that travels through pipes, usually set off by a sudden stop of the flow of water (stopping the moving column of water causes a wave to propagate backwards through the column?). Isn’t there a way to bleed the wave energy with proper venting of the system (a column of air acts to absorb the sudden spike in pressure)? I’m mostly making this up based on very rusty memory.
