Answer 1

If you are considering making a branch connection to a utility or service header without shutting it down to make the alteration, there is a connection procedure generally known as the "hot tap".

If this is your consideration, say so with "further Information" and I or someone else will proceed. Or else. you may locate many descriptions with illustrations by browsing elsewhere. Enter "Piping hot taps".

One site with a good basic illustration is http://www.epa.gov/gasstar/pdf/lessons/l...

If it is not this topic, please clarify.
