YES!! The idiots on this ng show complete ignorance agian. Read the
instructs on the stop leak product and it is intended for leaks in any rad
setup.
I have used BarsLeak with excellent success after watching a HVAC plumber do
the same and bill me $500.
Edwin has only seen rads in polish houses and polaks do not believe in heat
or sanitation.

Old radiator valves often leak at the stem and simply tightening the
nut on the valve helps, I would not want to add stop leak just because I
dont know how it could affect the boiler longterm, as the manufacturer.
What pressure is it at on the boiler in lb. Are there any signs of leaks
on the relief blow off. If it leaks you probably just have not looked
hard enough to find it.
