I'm just changing connections from cold/hot water feeds to Grohe 10yr old basin mixer tap and wish I had never started. The reason I wanted to change to flex hose was that the current connections had no service valve and also to get some practice in! Had both 10mm and 12mm flex hose + service valves to hand. Unfortunately the mixer tap connections in the 10yr old Grohe does not appear to take either a 10mm or 12mm screw thread. It looked like a copper push fit holding the hot/cold feed into mixer tap - I can see a thread but it's probably 11mm?! In getting the cold/hot pipe connections out (not screw thread!) I damaged the pipes, so can only think I will have to get a new mixer tap. The single hole in basin is 35mm. Do all modern mixer taps for single 35mm hole take either a 10mm or 12mm flex hose screw thread connection....please say yes!?
