i have a leak from my micro bore pipe into my rad where the pipe was hit by furniture.
can i isolate the rad and change the olive without draining the whole system?
i have an old fashioned open system with the two tanks in the loft....
thanks

I would suggest hiring a 'freezing kit', and freeze that section of pipe, obviously isolating that particular radiator and draining it.
