Just that really. The ensuite loo has dreadful limescale and the tap seems to have limescale build up as well and needs scrubbing or water only comes out of a bit of it. It's quite a wide spout.
The main bathroom on the same floor is absolutely fine.
I have started using the ensuite loo at lot during the day rather than the main bathroom in case it was a case of it not being used as much but it hasn't made any difference.
Any ideas as to why this might be.
