  1. I seen the Liquid nitrogen and brought back some memories . I spent 7 years on submarines . I was a reactor operator . We use it to freeze the pipe so we can fix the leak on the other side. I can not say  exactly  how the reactor works but I can tell you the hot water system has has only 2 valves . The problem with valves is the break down before the pipe. Man those were the days.
