This is called water hammer and can be addressed with a few tricks. The best is to secure the pipes and provide an expansion device ( these are small metal tanks with a "bladder" type balloon inside) it adsorbs the shock.
Thanks for the answers, but I'm still hoping for more ideas.
had the same issue, agree w/KMS works like a charm
Thanks for the answers, but I'm still hoping for more ideas. changed the controler made the noise twice as loud....only does it with the hot water. I've had three plumbers out, one charged $67 to look around, second charged $125 and told me to get some attachments for the washer and dryer, the third told me for $38 Hum, hum, I told him to leave.
Can you elaborate on this "controller"...not sure exactly what beast you are trying to tame...washer / dryer, dishwasher ...Kitchen or bath taps?
You need water hammer arrestors
Some noise can be had because of over pressure. Many times the pressure regulator is set to high and with some of the lower quality faucets they chatter when you turn them down for low flow or even when you attempt to turn them off. The cheep seals vibrate open and closed real fast which results in all kinds of strange noises coming out of the pipes. Check your pressure first. If that is not it, then follow Nichter's advice install water hammer arrestor.
