That is an option, probably the only one. There must be M14 tails somewhere though, the sink isn't that old. Someone probably has a stash somewhere, just not online.
I have already contacted them and unfortunately they no longer supply anything with M14 connections. I've tried every combination of search but can't even find an M14 to M12 adapter. Although the existing tails aren't reusable I suppose I could cut the ends off, fit new o rings and go from pipe...
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...
