Hiya guys and girls,
needing a little bit of help with diagnosing a pipe in our livingroom. Its about 2 inches above the floorboards running from inside the chimmney breast to the outside of the building. It has a little tap on it but it looks maybe 40-50 years old (1950's these were built) At one point there was a back boiler but its not there now. Our best guess is an overflow for the old water heating system/back boiler. Anyone any other suggestions??
