Great quality piece of kit if the price is anything to go by.

I think that's what the guy used when the incoming main gave way into
ours years ago.

It was in 3/4" galv steel 'gas barrel' and had rusted so thin, using
the stopcock in the back garden was enough to cause it to fracture (on
the incoming side) and so instant pond. ;-(

He turned it off in the road, dug down to the pipe and fitted a double
ended 'coupler' over the damaged area (still pretty rusty and gnarly),
tightened it up and that was job done (to my surprise).
