Is this pipe in use?
Recently moved into a 1950s house, the chimney breast was bricked over with another separate brick wall. After taking all the bricks off I found that the fireplace used to have a back boiler so there’s old redundant pipes that I want to cut..they’re not capped so I don’t think there’s any water left in them or anything..there’s also this pipework. The radiator pipes come down the inside of the chimney and exit into the kitchen feeding into the radiator so I know the ones on the left are fine and won’t be touching them.my question is can I remove the one with the drain on it or is it connected to the radiator system..I haven’t tried opening it yet to see if it’s dry or being used but it just seems like a really strange place to add in a drain at the end of the system..any thoughts would be greatly appreciated
