How do the experts mount newer taps to older basins, which have oversized square holes?
The large rubber washer which is used to create a watertight seal between the base of the tap and the ceramic washbasin, tends to distort and/or become displaced after a while of turning the tap on and off. This eventually permits water which has been splashed onto the surrounding area to leak down through the mounting hole and onto the floor below creating a damp patch. No amount of tightening of the (plastic!) nut on the underside will prevent this happening, so I was wondering if there is some sort of sealant that would effect a satisfactory cure?
Thanks for reading.
