Hi There, I'm hoping someone has the technical know how to help. I have a problem with one of my bathroom taps. I have a new build flat and it seems to be fitted with fairly cheap taps. Inside the tap head where it meets the spindle is a plastic cap. It appears to connect the tap head an spindle together. The problem I have is that this cap is broken and I cannot find these anywhere on the internet or even know what they are called. Do I need to replace the whole tap or can these be purchased separately? Any other ideas would be gladly appreciated.
