Leaking steam radiator relief valve
We have a steam system in an older house (1930s). Radiators in the basement and garage are on the ceiling, above the level of the boiler. The very large garage radiator is spilling water from the relief valve--a gallon or two per day when the boiler is coming on regularly. Our plumbing and heating service has tried replacing the valve a couple of times, using different sizes, but that hasn't helped. Someone has suggested that the radiator may be clogged and need to be descaled. Does that sound reasonable? And if so, how would we go about finding someone to do that? Any other suggestions?
