I rang up Russell after all the other recommendations here. Totally lived up to his excellent reputation. Had water pouring through and he got up an hour early this morning so he wouldn't be late for his other customers. Spotted the problem instantly, fixed it in five minutes, charged a fair price and then rushed off so he wouldn't keep anyone waiting. Top man. Totally professional and straight down the line. Strongly recommend him. He can be called on 07852 972 052.
