The cold pipe on my bathroom basin is leaking very slightly. It is on the mains so quite high pressure. The union was loose for some reason and although I have tightened it as much as I can there is slight seepage. The trouble is the floor is tiled so there is no give in the pipe at all so I can't remove it to fit a new fitting. I was enquiring about a flexible fitting and the plumbing merchants I enquired at said that they are useless on mains pressure. The trouble is to get the pipe out I will have to cut it but then how will I reassemble it. I don't really want to chip away the grouting but might have to.
