I have just noticed what looks like a flexible open ended vent pipe coming out of the top of our roof adjacent to the chimney. This is about two foot long and hangs down along the tiles. We have a normal vented (not sealed or pressurised) central heating and hot water system fired by a natural gas Rayburn.
Any information as to what this might be would be very welcome.
Many thanks, GSD.
