If anyone here is very knowledgeable about plumbing and heating please contact me at my email address below for a question about steam-radiator installation in my 99-year-old house. Please no posts to this group.
My house is 99 years old, so your experience may be just about right. I need to replace a single-pipe steam radiator with a larger radiator that's now sitting on my back porch. But the steam pipe into the new radiator is about half an inch higher than the one into the old radiator. So I either have to remove the valve and raise it (always a risk with hundred-year-old pipes) or cut down the feet of the replacement radiator.? Which would you?recommend?
The steel they made 100 years is different than today's . . The threads in pipe will be difficult to remove most time. The good news most of the pipe dope was lead it helps.? You may want to use dresser coupling on old pipe and try to remove from threads.?
It's low-pressure steam, so I assume it's at 212 F.? ?The radiator are replacing was installed probably no more than 25 years ago to replace a bigger radiator. The rest should be doable if I can get the spud out of the old radiator.
What you are dealing with is called an “offset”.? The easy solution here would be to add two 45 degree elbows, street elbows, and/or the appropriate length nipples between the valve union and the new radiator.? This will allow you to adjust the offsets between the horizontal and vertical axes of the valve and the input to the new radiator to the exact dimension you need.? ???

Since he needs to go up only 1/2" you would not be able to get that short of offset without moving the radiator forward or back or raising it even with two 45 street ells.
