My next door neighbour dropped by this evening to see if we were having problems with our water which we weren't. Nosey as i am I went into his house to have a look. The water was coming in at tap downstairs but his tank wasn't filling in the attic. He was away for a few days over Christmas and that heat wasn't on but I wouldn't have thought the pipes were frozen or anything. they didn't seem too cold. Any suggestions? Any solutions?
