The rubber washer seal on a radiator drain valve normally gets damaged by over-tightening it when closing. It really doesn’t need to be that tight, as it’s rubber. Radiator drain valve with inner removed A leaking radiator valve is not really an emergency. It can cause damage to flooring, electrics, and possibly the rooms below the leak, but I have not seen an emergency situation come from a leaking radiator valve in over ten years of plumbing.
