richardson HEAT radiator traps
I have a building that has twenty four of the Richardson HEAT traps with the little plug on the side. I read some posts from 2009 regarding these traps. Looking for clarification that there are no moving parts to these traps and that if radiator is not heating to unscrew the plug and clean the air hole? If this is true there should be no reason to replace? Thanks for any help.
