Dear reader,
Can anyone explain the science behind the following situation i encountered?
The feed pipe from header tank to inlet on an indirect cylinder is very corroded with visible holes. If I shut the gate valve that stops the feed from header tank the pipe from valve to bottom of tank doesn't leak. shouldnt the weight of water in tank back up that pipe as it has holes in it? Even if i cut the pipe below the valve no water leaks out, can anyone explain why? Does that mean I can cut very close to inlet in tank and it still not pour out? Thanks for all those a lot cleverer than me out there.....which is probably most of you!
