I actually used the bread trick for the first time today on a job in a top floor flat. I drained down the heating system to install new TRV's and replace some butchered pipe, more on that later!! This old heating system just would not completely empty. I tried syphoning it out, using the end of a spray bottle, blowing it etc. so I left it while I had my lunch. A subway and remembered the old break trick. Got back in there and stuffed some down the pipes minus the steak and cheese. Soldered it up and perfect. I was literally about to use a compression coupling. I was impressed! Doesn't happen often.
