Question Author
I live in a block of flats and as far as I know, all the water comes from one main tank in the loft so I can't understand why it can be flowing from some taps but not from others. If the whole supply was gone it would make sense than the pipes coming into the flat were frozen - especially since they come through the flat upstairs first and that flat is empty. Mainly I'm just ticked off cos I can't get a shower or even a bath :(
Thanks everyone x
ps - yes doc, it's a combi. Only got it last year and never had any problems when I had a water tank...
