I have replaced my knackered one. My new one makes the water pipes vibrate through the house. Anyone else had it?

Don't have a problem with my pipes. In my case it depends on what's on my draining board in the kitchen as it's a stainless steel one. Sometimes I get all sorts of rattling and buzzing going on going on when my pump is operating. First time it happened it had my wife scratching her head trying to work it out.
