hi this is a real long shot but our tap that was installed by mfi around 15yrs ago has started to leak, normally we would just buy another but we really like this tap....a plumber came round to see if it could be mended but he said without the make and model of the tap it would would be very difficult to fine the correct cartridge to fit. so before we buy another tap is there anyone that worked at mfi and recognises our tap??? thank you
