I tried to remove a radiator ready for painting the walls in my extension i had built.The rad pipes come out of the screeded floor and protrude about 4 inches.I've drained the rad and undone the nuts at either end but the only way to get the rad off is to bend the copper pipes.I tried to bend them but i did not want to apply to much pressure as i was scared of busting the pipe.The question is how forgiving is copper pipe or should i just leave it and paint behind the rad using a small roller.
