Hi hope you can help. I need to re seal a leaking connection to a rad. It's 8mm microbore. None of the rads have drain cocks. I've been told the only way to drain the system is to turn off the valves on one rad, remove it and rig up a hose to the valve and drain it that way. I suppose I could freeze the pipe but those aerosols never seem to work that well.
Can I do it through the boiler?
Many thanks
