I'm in the process of removing 5 hot water radiators from my 1917 home to have them sandblasted. I'm hoping to get some advice from the forum in two areas...
#1 -- Though I've completely loosened the large nuts on the supply and return sides of the radiator (see pictures below), the radiator won't budge.
There isn't enough clearance on either side to slide the radiator out of the way. The valve stems seem to extend, and are nested, within the valve itself. Do I need to turn the other larger nut (closer to the radiator fins) to back the valve stem away from the valve? Any advice is appreciated.
#2 -- I've found a shop that will sandblast my radiators, but is there anything I need to be careful/watchful of, in getting this done?
