I've just received a ceramic sink, Belfast 200 from Carron phoenix and I am informed that I need to open a hole in the centre to allow a tap to be fitted. The area that the tap is located is pre prepared underneath for cutting through the ceramic surface. However, I'm not sure how to actually cut through the pre- prepared area in order to fit the tap. It appears to be scored underneath. Does anyone have any experience in opening a hole in this ceramic double sink. Do I need to score the glazed top surface? and how do I do that to prevent the glazed surface from splintering and or cracking. I would be grateful if you could pass on any tips or advice that may be relevant.
Regards
Don
