I have an old house with a radiator system, and am needing to take a radiator out. While some of the radiators in my house have nuts on both ends of the radiator, making it easy to remove, this one only has a nut on one end. On the other end is a straight pipe coming out of the radiator, which threads into a 90-degree elbow, and so on.
There's so much paint on the pipe that I can't tell whether the end connecting to the radiator is threaded or whether it's a part of the radiator itself. Thinking it was likely threaded, I tried holding the elbow still while cranking on the pipe, but it wouldn't budge. Before I get out the sawzall or crank more on the pipe, I thought I'd get others' thoughts on what the right way of going about this is.
Is there a way to disconnect the pipe from the radiator? If I used a sawzall, am I ruining a part of the radiator itself? Or could I sawzall it and somehow get the ends of the cut pipe out of the radiator and the elbow, and then replace the pipe w/a better solution that has a nut? I need to be able to re-install the radiator later in the same location.
