we've recently installed a new sink and monobloc mixer tap. now, when we use the cold water up to full pressure, water continues to dribble out of the tap for around 30 seconds after the tap has been switched off.
is this a problem with high water pressure (since it doesn't seem to do it if we turn on the water just a little) or is there a problem elsewhere - i.e. the tap unit or the plumbing?
any help would be much appreciated as this is driving us up the wall!
