The best bit of pipe bending I ever saw was in a down stair toilet in an old country cottage.
The pipe must have been 4M long, and there was no way it would have got into the room, as it was a small room.
I've no idea how the bloke did it. But it ran all round this room, crossing over obstacles, and kicking as it needed to. All perfect.
I wasn't the only one to notice it. The joiner came back from using the loo and said, "have you seen that length of copper tube in there"?
I 'd love to be as good as the bloke who did it. I would save a fortune on fittings!!
I wish I'd taken a photo. Best thing was that it hadn't been painted so you could appreciate it for what it was!
Sad isn't it!
