Default How long does it take to thaw out an underground pipe?

In article ,
lid says...
Said 15" pit is now filled with (removable) insulation.
New job on list: fit new deep large bore mains water feed.


Large bore would flow more slowly, making it more likely to freeze, I'd
have thought. Provided the bore is sufficient not to restrict flow below
a useful level, I'd leave it narrow.
