Where are the leaks?
The most common causes are the packing nut which is around the stem of the valve handle, snug it up and at the union halves. This may mean the same radiator did not go back to the same room. Unions mate after a few years and need to stay mated after that. Try a little pipe dope on the face of the union without getting any dope inside the union.
