It could be there's a leak somewhere, and opening this rad's vent is
like taking your finger off a filled straw. I'm assuming you don't see
any evidence of water leaking after you've tried to bleed this rad? Do
any pipes go through the slab? Is there pressure in the system (I'm
assuming there's a pressure tank..)? If there is a tank, and it's hung
below the piping, a failed diaphragm would allow water to enter the
diaphragm side when the rad vent was opened.
