I've had a new kitchen fitted but kept my old Franke sink and monobloc tap, approximately 15 years old. The fitter has had to leave the taps disconnected as he wasn't able to find tails suitable for the tap. It has an M14 female thread whereas M12 or M10 are all that are available. Can anyone suggest where I can find flexible or rigid M14 tails or alternatively an M14 to M12 adapter that would allow the use of an M12 tail. He wrecked the old tails getting them off so I can't reuse them.
