Your Question– “The water meter out in the front of our townhouses have been changed to a smaller size (I think smaller), can this make my pipes knock? Only the washing machine used to do it, now all the taps do it when they are turned off, they also leak now too. Constant dripping. Thank you.”
Our Answer– In our opinion, it sounds like they may have turned up your water pressure. Check the pressure and if it is high then have a pressure reducing valve installed.
