Hello, Live in a small 3 bed semi. The bathroom taps upstairs are supplied from the mains. In the last few (very hot) days both the cold bath tap and the basin mixer tap (when turned to cold) make a horrible vibrating noise when turned on or off. The bath taps actually growls for a couple of minutes before subsiding. No recent alterations to plumbing. Only thing I feel could be causing it is the weather? Any suggestions/fixes much appreciated. Cheers.
