A word of warning though. Are you absolutely sure there are no other

in the pipe? It tends to happen to cast iron if under any stress for a

time that cracks grow and propagate, depending on where the minute flaws
are. It might be that in the end a new plastic pipe is less of a hassle.

That sounds like a complete lash up. If he wants to preserve the
authentic look of the pipe, he'd do better to Google for a replacement
pipe for that particular cracked section, IMO.

Certainly a better option, but he did ask for a repair and IMO, this is
the simplest way to meet the need to stop the leak. BTW it should be
possible to get an identical looking replacement in cast aluminium,
which is easier to handle and is less brittle.

Yes, an aluminium replacement is a good idea, maybe a bit pricey though,
I would have thought.
